[00:01] it's 1am here, you know :) [00:03] ah sorry, you'll be sleeping soon. [00:03] well, don't wait on me. i'll figure it one way or another. i'll be here tomorow as well.. i need to get this done this week. [00:04] run pvcreate with -vvv [00:04] ok [00:04] it might give you a clue what's going on [00:05] thank you for the insight. [00:05] you've already created md0? [00:05] yes, it should be there.. i just deleted and recreated it in the installer [00:06] when i used the installer to set the LVM on it - it said the same thing in the command line (couldn't find /dev/md0 or it was filterd) [00:07] run pvcreate with -vvv [00:07] i'm not there yet, but when i get there, i will. [00:07] hey guys i am having issues with cron.d not working…. i have */5 * * * * www-data php -q /var/www/mydomain.com/tickets/public/api/cron.php [00:07] rebooting now [00:08] it doesn't seem to run [00:08] webPragmatist: use full path to php [00:08] and check /var/log/syslog [00:09] ivoks: okay thanks [00:10] oh i get Error: bad username; [00:12] mdadm -D /dev/md0 .. currently says it's rebuilding (38% complete) [00:13] AndyGraybeal: that could be a reason why it isn't working [00:13] okay, i'll wait for it to build. [00:13] try pvcreate anyway [00:14] oh idid..it says the same thing; and -vvv is lots of data, how do i redirect it into a file? [00:14] oh on boot up i noticed an error cannot find /dev/null ... i was like.. that sounds bad! [00:14] but it's there.. so i odn't know [00:16] 10 years and you still don't know how to redirect stdout? [00:16] bad windows sysadmin :) [00:16] well i tohught it was like > filename [00:16] 1> name_of_the_file 2>&1 [00:18] k i've never seen that before, thank you. [00:22] here's the pastie: http://pastie.org/1061328 .. there's a lot more devices it lists.. but i figure you'd get the drift from here - i think this is the meat of the matter. [00:23] it says partition table signature found, skipping. is that the problem? [00:23] yes, it is [00:23] is that resolved with parted? [00:24] mdadm --stop /dev/md0 [00:24] what disks/partitions are in /dev/md0? [00:24] which [00:24] i'm not sure, how do i find out? [00:24] i thought i removed all the partitions. [00:25] i thought i actually re-created the whole array when i re-installed. [00:25] i mean, i remember going through the motions atleast. [00:26] fdisk -l doesn't show anything [00:27] dmesg | grep '320 GB' [00:27] but maybe tha'ts cause i --stoped it [00:28] did you run what i said? [00:28] http://pastie.org/1061336 <--- yes [00:28] yes, sorry it took me a second [00:29] so, it'd sdb->sde [00:30] fdisk -l /dev/sdb [00:30] fdisk -l /dev/sdc [00:30] fdisk -l /dev/sdd [00:30] fdisk -l /dev/sde [00:30] check if there are any partitions on those disks [00:30] if there are, delete them [00:30] okay [00:30] it looks like the block size is different in both those pasties, the last one is 512bytes, and the first one is 4096bytes (i don't know if this has anything to do with it) i'm going to do the fdisk -l now. [00:31] they all have: Linux raid autodetect as the "System" [00:32] paste output of one of those disks [00:32] k [00:32] http://pastie.org/1061344 [00:32] delete those partitions [00:33] or [00:33] wait, don't [00:33] k, yea, i htink i need them for the RAID [00:33] not really, but anyway [00:34] okay, yea, i have no idea. [00:34] mdadm --zero-superblock /dev/sdb [00:34] mdadm --zero-superblock /dev/sdc [00:34] mdadm --zero-superblock /dev/sdd [00:34] mdadm --zero-superblock /dev/sde [00:34] ok [00:34] oh maye i need to turn md back on? [00:34] mdadm: Unrecognised md component device - /dev/sdb [00:35] did you stop the array? [00:35] you had asked me to, i haven't startd it back up yet [00:35] ok [00:35] try with sdb1 [00:35] should i start the array? [00:35] oh sdb1 nm [00:35] worked [00:35] i'll keep going [00:36] right [00:36] k, all done [00:37] should i try pvcreate now? [00:37] er i guess i should start the array, but i'll wait for further notice. [00:37] mdadm -A /dev/md0 [00:38] then pvcreate [00:38] k [00:39] after: mdadm -A /dev/md0 .. it says: mdadm: no devices found for /dev/md0 [00:39] gah! [00:39] mdadm -A --scan [00:39] lol, i'm stupid :) [00:40] same answer [00:40] you've cleand the superblock [00:40] of course it won't work [00:40] okay. [00:40] so recreate the array? [00:40] ivoks, sorry had an appointment, donno if it boots from the disk in fact because the grub screen never shows [00:40] mdadm --build /dev/md0 --level=5 --raid-devices=4 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 [00:40] ah --level=10 for me [00:40] ivoks: heya...dovecot 2.0 is suppose to be out in a couple of days...whadayathink? [00:41] unless you think level=5 is better [00:41] ivoks, I even went in the bios to tell it to boot from second hard drive [00:41] lox_: did you replace the disk with boot partition? [00:41] zul: i was a bit off for some time; i have to catch up with what's new [00:41] ivoks, yes it has a boot partition with bot flag (the boot is in the raid1 too) [00:42] And I already copied the parytition table of sdb to the new sda [00:42] AndyGraybeal: i was under impression that you are building raid5 [00:42] raid10, and it says to use 'create' instead of 'build' [00:42] right, create [00:42] go ahead with that, otherwise, i'll take your recommendations. [00:42] ivoks: okies...i was tempted to [00:43] zul: we might :) [00:43] zul: give my just some time to examine everything [00:44] ivoks, everything is checking out; should i wait for rebuild or should i just go ahead and try pvcreate [00:44] ? [00:44] ivoks: no problem [00:44] AndyGraybeal: do pvcreate [00:46] ivoks: same response: /dev/md0 not found or ignored by filtering; .. the -vvv returns the same; partition table signature found, and fdisk -l reports the same: Linux raid autodetect. [00:46] time to hit the bead... [00:46] bed [00:47] alright, thank you for your help ivoks. [00:47] AndyGraybeal: then just wait for it to build [00:47] okay thank you [00:47] never did md level 10 [00:47] okay; i don't know what to think about it in comparison with 5 [00:48] paste output of cat /proc/mdstat [00:48] i used to do 5 with evering [00:48] http://pastie.org/1061358 [00:49] What would be a good way to do a VoD/File Server/Voip System [00:49] I was originally going to use xbmc for VoD [00:49] AndyGraybeal: wait for it :) [00:49] good night [00:49] but then I just went with simple file sharing [00:49] ivoks: thank you [00:49] for VoD and file server [00:50] but I feel like that is a very poor solution [00:50] Jinxed-: what is VoD ? [00:50] AndyGraybeal, Video On Demand [00:50] basically to allow for streaming video [00:50] aah ok, thank you === mdeslaur is now known as mdeslaur-afk [00:51] aka I don't want to broadcast, I want to allow remote users to request a stream [00:51] Any suggestions? [00:51] well, your aware of asterisk for voip, i'm sure. i've set that up before and got it to work.. so if i can do it, it must be fairly straight forward. [00:52] haha [00:52] yeah I was planning on using asterisk [00:52] i shouldn't be allowed to answer questions though, they should keep me in a cage and ask the on-lookers not to feed me. [00:52] i was even tempted to try * with vmware so I could use AsteriskNow [00:52] fileserver, i guess would be samba or nfs if your all *nix [00:53] i would use asterisk straight up, it's fairly easy. [00:53] the guys in the channel are pretty nice too [00:53] #asterisk that is [00:53] they told me to use AsteriskNow [00:53] but yeah I would be willing to try Asterisk with ubuntu [00:54] asterisknow is linux, vmware is not needed correct? i would us KVM and not vmware, but i'm sure that could be a holy war in a bottle. [00:54] someone mentioned trying to use zfs [00:54] zfs is more for bsd, but i'm sure someone here can answer better than myself. [00:54] haha, i actually was going to use virtualbox [00:54] for virtualization [00:54] so I could just basically have the two OS [00:54] i wouldn't run any server program in virtualbox; i would stick with kvm, but like i said, i shouldn't be answering questions. [00:55] haha [00:55] alright [00:55] you should wait for osmeone else to respond before you listen to me, seriously [00:55] It seems like simple file sharing (right click share folder) is a poor system [00:55] ivoks, so, no idea why it won't boot from sdb ? [00:55] lox_: ivoks went ot sleepytime [00:56] AndyGraybeal, oh, ok ... Can you help me with my raid problem ? [00:56] lox, no no no bro.. i'm trying to strangle myself with mdadm as we speak. [00:57] AndyGraybeal, so what server features should I install on top of the regular desktop installation [00:58] Jinxed-: i would do the opposite, install server, then install ubuntu-desktop ontop of that. but you'd probably want atleast openssh-server, you'd need the KVM stuff for virtualization if that's where you wanted to go. [00:59] Jinxed-: i run samba for fileserver but only because i got to run some windows boxes.. i'd probably do NFS otherwise... i've never touched ZFS, so i can't tell you what about that. [00:59] my finance ladies won't learn openoffice and i swear my hair falls out when i run MS Office in wine... so windows boxes it is (even if they are KVM'd) [01:01] ha, well currently i just have ubuntu desktop [01:01] my whole group is fine wiht openoffice accept the finance ladies.. makes me angry, they gang together.. saying that the calc, now called spreadsheet or something is too different and they don't want to learn something different. [01:01] i don't have any server features (except for vlan and samba installed) [01:03] sudo apt-get install openssh-server ... atlest. [01:03] you should read about KVM and libvirt; ubuntu has nice docs! [01:03] you happen do be able to donate a link? [01:03] i use kvm with libvirt, i like 'virsh' the command line that controls the virtual machines. [01:03] :p [01:03] yea hold [01:04] https://help.ubuntu.com/community/KVM [01:04] there is also #ubuntu-virt and they are huge help [01:05] and #kvm and #libvirt if i recall correctly [01:05] lox_: i'm building my array as we speak, 38% done. [01:07] Heya. :) [01:09] hi beefstake :) [01:13] AndyGraybeal, can i rebuild my array from livecd ? [01:14] lox_: if it's a mdadm raid array then you should able able to yep. [01:14] beefstake, hi, yes it is [01:14] Mhmm yep you should be fine. [01:15] beefstake, I needed to replace sda and do removed it from the array, shutdown, replaced disk and it won't boot from sdb [01:15] RAID 1 yep? [01:15] yes [01:15] Did you have the md device set as the boot device or one of the raid members? [01:16] beefstake, yes [01:16] a boot partition in raid1 and a / partition on raid1 too [01:16] Ahh kk yep. [01:17] beefstake, but won't boot from sdb and I am stuck there [01:20] lox_: What you need to to then is boot up the live cd [01:20] Then force assemble the array. [01:20] beefstake, done [01:20] how ? [01:20] http://gist.github.com/491501 [01:21] Ahh like sdX5 are the / partitions? [01:21] yes, what is wrong with it ? [01:21] Well you need to do both anways [01:21] So you do it like this: [01:22] Hmm wait, have you recreated the partitions on sda yet? [01:22] yes [01:23] using sfdisk [01:23] Kk cool. [01:23] mdadm --assemble --force /dev/md0 /dev/sda5 /dev/sb5 [01:23] http://gist.github.com/491506 [01:23] Should complain about not having a superblock. [01:24] true [01:24] mdadm: no recogniseable superblock on /dev/sda5 [01:24] mdadm: /dev/sda5 has no superblock - assembly aborted [01:24] Yep k. [01:24] mdadm --assemble --force /dev/md0 /dev/sb5 [01:24] We will add sdb in just a sec. [01:25] mdadm --re-add /dev/md0 /dev/sda5 [01:25] Try those 2 [01:26] $ sudo mdadm --assemble --force /dev/md0 /dev/sdb5 [01:26] mdadm: cannot open device /dev/sdb5: Device or resource busy [01:26] mdadm: /dev/sdb5 has no superblock - assembly aborted [01:26] sudo mdadm --re-add /dev/md0 /dev/sda5 [01:26] mdadm: cannot get array info for /dev/md0 [01:26] Wait, what. [01:26] Which is the drive that didn't fail? [01:26] sdb [01:26] That can't be right.. [01:27] I hotremoved sda, shutdown and replaced it, then rebooted [01:27] Hmm. [01:27] Has it won't boot, I loaded live cd and copied partitions to sda [01:27] yeah. [01:27] cta /proc/mdsat gives nothing from livecd [01:27] The issue here is that sdb is reporting that it doesn't have a raid super block. [01:28] what did you use to copy partitions? dd? [01:28] Yeah because no mds are running. [01:28] no sfdisk [01:28] lox_: aah.. *googles [01:28] Nah you shouldn't dd them, you should only copy acroos the partition layout with sfdisk. [01:28] This is what I have done [01:28] mdadm should resync the disks once you readd them to the array. [01:28] I used sfdisk and copied only the layout [01:29] The issue here is that sdb is saying it doesn't have a superblock... [01:29] it worked yesterday, I used exactly same process to replace sda (and of cource I waitied resync to finish) [01:29] (needed to replace both because of SMART errors)7 [01:29] Mhmm. [01:29] But it booted on sda when removed sdb [01:30] now it won't booton sdb, why ? [01:31] Is that normal (from livecd): [01:31] $ cat /dev/md0 [01:31] cat: /dev/md0: No such file or directory [01:34] $ mdadm --detail /dev/md0 [01:34] mdadm: cannot open /dev/md0: No such file or directory [01:34] is that normal ? [01:36] beefstake, can I try mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdb5 /dev/sdb5 ? [01:36] Or it may erase my data ? [01:39] Yeah don't use create. [01:39] Create is bad. [01:39] beefstake, why don't I have /dev/md0 when I boot with the livecd ? [01:42] sounds scary lox_ do you have your data backed up? [01:42] arf ... part of it [01:42] hopefully beefstake can help :) [01:42] i'm sure he can. [01:42] i'm on the edge of my seat hoping there is a good outcome. [01:43] The array was working so nicely ... [01:43] how long? [01:43] many month [01:43] nice [01:44] sudo mdadm --assemble --scan [01:44] mdadm: /dev/md0 has been started with 1 drive (out of 2). [01:44] mdadm: no devices found for /dev/md1 [01:44] cat /proc/mdstat [01:44] Personalities : [raid1] [01:44] md0 : active raid1 sdb1[1] [01:44] 476519872 blocks [2/1] [_U] [01:44] [01:44] unused devices: [01:44] beefstake, ? [01:45] that means all your data is there, correct? [01:45] I miss sdb5 [01:45] where all data is [01:46] oh tru my data is here [01:47] and boot is on it too [01:47] maybe back up now before things get worse [01:47] so sdb5 could be swap [01:47] AndyGraybeal, sure ;) [01:47] i hate living by a thread :) [01:48] AndyGraybeal, should I use dd ? [01:48] the fastest backup solution will be the best ;) [01:48] oh i have no idea, maybe that find and cpio or rsync to another drive just to be safe. [01:48] you should lisgtne to someone here, not me. i'm a newb [01:48] dd would be slow i assume. [01:49] you saw how ivok was scolding my ignorance :P [01:50] ;) [01:54] Backing up [01:55] What is the best way to handle swap partitions in a raid1 array ? I have added the swap partition to the raid1 aray is it theway to do ? [01:56] what are you using to backup (curious)? [01:56] rsync [01:56] I could have used cp -a [01:56] i've been reading that cp -a isn't a good solution, that find and cpio is better, or rsync. [01:57] but i'm not sure honestly [01:57] Basically rsync does what cp -a does with some feature like incremential backup [01:58] http://www.mikerubel.org/computers/rsync_snapshots/#Rsync [01:58] okay [01:58] AndyGraybeal, but for everyday use, I use rdiff backup [02:00] ah nice [02:00] yea, i just read now that rsync is a bad idea because of the overhead it might take while trying to 'sync' to a empty destination [02:00] so many variables :) [02:01] rdiff backup only backs up diff changes between files, so I can backup every two hours with it [02:03] I stil don't see why it is not booting from sdb alone, everything is there: grub, boot flag [02:12] okay, my problem is that i can't seem to build a LVM on top of a newly made array. when i try 'pvcreate /dev/md0' it says: "Device /dev/md0 not found (or ignored by filtering)" but that error is a little bogus because when i do pvcreate -vvv /dev/md0, it says: " /dev/md0: Skipping: Partition table signature found" .. so this is where i am stuck. i don't know what to do. fdisk says this: http://pastie.org/1061462 ... [02:13] if anyone can help me get rid of this GPT on my raid array, that might move me forward in creating an LVM on it. [02:15] AndyGraybeal, sorry I dono LVM, never foudn a use to it ... [02:16] lox_: thank you for the response. yea, i was going to give it a go, see how things worked out. [02:16] What do u need lvmfor ? [02:17] an added layer of failure (in most cases) [02:18] lowridah, that is whta I miss it seems, for me LVM is just usefull for resiing patitions [02:18] lox_: yea, i hear i can resize partitions on the fly too, that sounds nifty [02:18] lox_: i don't know, maybe it's another layer of confusion i don't need, but i was gonna give it a shot this time around. [02:18] AndyGraybeal, a long time I have not used many parition for one system.... [02:19] i want to have my /home and /srv as seperate partitions [02:19] i got 70 users and i don't know how things will go in the future, so we'll see. [02:21] AndyGraybeal, what is /srv used for ? I only saw ebox using it until now ... === jjohansen is now known as jj-afk [02:21] Guys.. I need some help with a EUC setup. I've been pouring over the docs and found that I shouldn't be makeing edits to the network stuff in eucalyptus.local.conf but should be using eucalypts.conf (acconding to open.eucalyptus.com).. hovever, the changes I make there never seem to get into the local file and the local file takes precidence it seems. [02:21] Now... the local files has a big warning about not changing it directly.. so WHERE THE HELL DO YOU CHANGE THINGS??? [02:21] I'm trying to setup some IP's that are public so I can see the machines from the outside [02:23] lox_: i'm gonna use it for all my users data.. aside from their /home (personal data) of course. my computer acts as a file server.. so that's where their shared files will go. [02:23] lox_: read .. file system hierarchy and it gives and explaination [02:23] lemme bring up the url [02:24] http://www.pathname.com/fhs/pub/fhs-2.3.html#SRVDATAFORSERVICESPROVIDEDBYSYSTEM [02:26] AndyGraybeal, thks for the link, bookmaking it [02:27] yea, i think i'm gonna head out -- i will get back on this in the AM here on EST. [02:28] lox, what is ebox? [03:40] hello people [03:45] jeez those f.... centos people are idiots [03:45] Lol [03:45] What did they do now? [03:47] wizardslovak: I found a lot of them nice to talk to now and then [03:48] huh [03:48] ask question ? [03:48] bs [03:48] i did and none to help , just started bitching about how untechnically i am and how english is barrier to learn , wtf? [03:51] Lol. [03:51] Fail. [03:51] What did you need to know? [03:51] I use CentOS a fair bit. [03:51] damn sudoers file [03:51] but forget it , ill use ubuntu from now on [03:52] beefstake, u have a few minutes? [03:52] also that ubuntu is as easy as windows , so no technicall people stop on debian , huh as i said idiots!!! [03:53] lox_: Yeah, you still having trouble with your raid? [03:53] beefstake, mdadm --assemble --scan found my md0 aray but not the md1 (swap) [03:53] I added sda to md0 [03:53] it syncs as I speak [03:54] lox_: Nice, you are home free then. :) [03:54] But what about md1 (swap) can I start without it (still in livecd session) [03:54] That's fine, your system will boot without swap. [03:54] ok [03:55] now what do u think of my weird problem of not being able to boot on sdb ? [03:55] md0 is in grub [03:55] boot is in md0 [03:55] always liked ubuntu people , so kind ;) thx whoever invented ubuntu [03:55] it has grub in it [03:55] Anyone have IS C config and Ubutun 9.x and upgrade to 10.x and feel good? or were there issue or major problem [03:55] and the boot flag is set on the partition [03:55] Mhmm.. [03:55] beefstake, I ask it because of what could happen if sda fails again ... [03:55] lox_: That shouldn't have been an issue though. [03:56] lox_: What should normally happen is you boot with the array in a "degraded state" [03:56] Meaning that a disk has failed. [03:56] Not big deal, it should just boot. [03:56] I think something went wrong when you were removing disks or something. [03:57] beefstake, you have to grub-install to each disk you want to be bootable [03:57] to the MBR [03:57] qman__: Ahh completely forgot to remind him of that. [03:57] otherwise the BIOS loads the MBR of your other disk and doesn't find anything to load [03:57] beefstake, thks bro, I hope it will boot after sync, I think the issue may be the bios ... [03:58] lox_: As qman__ said you need to do grub-install on each disk in the raid. [03:58] You will need to reinstall grub to the MBR of sda now you have replaced it. [03:59] do I just do grub-install /dev/sdb1 ? [03:59] from the livecd ? [04:00] You will probably have to mount it first but yep. [04:00] pretty much [04:00] I can't remember if there's more to it, but that's the idea [04:00] did anyone used ubuntu jetos? [04:00] and no, it doesn't need to be mounted [04:00] i mean jeos [04:01] qman__: Yeah? How does grub-install determine the bios disk of /boot then? O.o [04:01] sudo grub-install /dev/sdb1 [04:01] /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). [04:01] No path or device is specified. [04:01] I cannot mount sdb1 it is a raid partition [04:01] oh yeah [04:02]
