[03:47] if i installed onto btrfs can i do a snapshot of the entire os? or only sub volumes? [03:51] what is the difference? [03:51] aren't they one in the same? [03:52] i may be mis understanding *first time ever relly spending any time thinking about filesystem things [03:56] what would the command look like ? something like "btrfs subvolume snapshot / snapshot-name" ? [03:59] with btrfs, everything is a subvolume [03:59] you can view them different ways, like point in time views, if you wish [03:59] dunno how flexable they have made it yet [04:00] but technically it could even do multible streams from the same base [04:01] it's been alittle over a year since I used btrfs [04:06] ahh thanks tho :) it all helps [04:09] any chance you rember how to restore a snapshot? [04:09] restore? [04:10] .. if a take a snap shot of something .. then brake it .. how would i go back to that point? [08:51] hey does anyone have the slightest clue how ftp-proxy works with ubutnu? i can't find anything worthwhole on google, and the docs for it makes no sense to me :( [09:02] New bug: #811428 in apache2 (main) "Apache does not honor -FollowSymlinks due to TOCTOU, which allows access to /proc// files" [Undecided,New] https://launchpad.net/bugs/811428 [09:45] <_johnny> hi, i'm running ubuntu 9 (karmic) and have some troubles setting up wlan properly. i have gnome, and installed network-manager-gnome and set the network up just fine. got ip, able to resolve etc. however i'm unable to "make available to all" for the wireless connection. it's simply greyed out. any ideas? === zz_ng_ is now known as ng_ [10:11] _johnny: are you logged in as someone with "sudo" privs? === ng_ is now known as zz_ng_ [11:12] New bug: #278075 in dapper-backports "DSBL is gone and needs to be removed from SpamAssassin" [High,Fix released] https://launchpad.net/bugs/278075 === zz_ng_ is now known as ng_ [13:23] Hi [13:26] I am new to ubuntu server - my previous setup was Centos 5.5. so 1) i am used to using a GUI interface - any suggestions as to a suitable GUI for Ubuntu? [13:50] Hey [13:51] Does anyone know a decent way of manaing LVM and by extension LUN setups on a Ubuntu server? Preferably web/console based with a decent UI [13:51] Doing this by hand is a .. git. [13:52] New bug: #811518 in samba (main) "SAMBA cannot browse Workgroups, name resolve order" [Undecided,New] https://launchpad.net/bugs/811518 [14:19] heh, it's simple by hand [14:20] but what do you mean by extension LUN setups? you mean iscsi? [14:20] Well more resizing [14:21] if you purely want a web system to do that, look at openfiler [14:21] Its fecking harrowing trying to *shrink* a LVM since if you do it wrong you butcher the data [14:21] well, that's a given :) [14:21] LUN's are easy [14:22] its just.. I dont like poking LVM's espically resizing when I can help it [14:42] whois chex === ng_ is now known as zz_ng_ [16:16] What if any is the downside of LVM on a server, and conversely what is the upside? [16:17] LVM offers more flexibility than direct partitions at the expense of some minute amounts of space and the overhead of an abstraction layer [16:23] qman__: thanks, I am new to Ubuntu, I was using Centos, my server died PS problem blew everything, so I am setting up a new server. my current needs are postfix/dovecot & webdav. HW config phenom II, 8Gb, 4 x 1Tb hd. 1st problem how to config HDs, then on to SW. Any advice would be welcome, in fact its desperately needed! TIA [16:25] depends entirely on your load, importance of data vs performance, etc... [16:25] quad core phenom? [16:26] postfix+dovecot is easy to do on ubuntu, I haven't done webdav [16:27] New bug: #811568 in squid-langpack (main) "Sync squid-langpack 20110707-1 (main) from Debian unstable (main)" [Wishlist,Confirmed] https://launchpad.net/bugs/811568 [16:27] if speed and reliability are more important, I'd do raid 10, if capacity and reliability are important, raid 5 [16:27] regardless of what you choose, I'd do mdraid (it's in ubuntu's setup) [16:27] qman__: quad core = yes. [16:28] then raid 5 should perform well enough provided you have a half decent disk controller [16:28] AMD 8 and 9 series are good enough [16:28] for four disks at least [16:29] but if you want the most speed, 10 is better [16:29] qman__: I had thought of adding a 5th as a spare, but the pocket book need to rest. [16:30] most important thing is setting up smartctl [16:30] a couple years ago I lost a raid 5 array when three drives died the same day [16:30] had I had smartctl set up properly I would have gotten a few days warning [16:31] qman__: would /boot - raid 1, swap - raid 0 , /tmp raid 1, /root raid 5/6, /common raid 5/6 (long term data store) as partitions be reasonable, or would I be better to put rrot and common under LVM. [16:32] that's way more complicated than it needs to be [16:32] unless you plan on actually needing lots of swap, here's what I would do [16:32] on each drive, create one partition ~512MB at the beginning [16:32] qman__: thanks for the warning about smartctl! [16:32] then one partition the rest of the size [16:33] mirror two of them as /boot, use the other two as swap [16:33] then set up a raid 5 or 10 on the other four big partitions at / [16:34] the reason being [16:34] you're only working with the same four disks [16:34] splitting up partitions like that is only really helpful if you have separate hardware to put them on [16:35] if you want to split up / and your /common, that's fine too, but all that other stuff is just not needed [16:35] and raiding swap is not necessary [16:36] because you just create two swaps, and it will use what is available [16:36] New bug: #811571 in librdmacm (main) "Sync librdmacm 1.0.14.1-2 (main) from Debian unstable (main)" [Wishlist,Confirmed] https://launchpad.net/bugs/811571 [16:37] can I boot into a raid 5, on centos /boot had to be on a single drive or a raid 1 [16:37] you can, though depending on hardware it may not work on the first try [16:37] getting grub to play nice can be a pain, but it can do it [16:38] OK, so for ease of ?setup/ops? /boot on a raid 1, swap across all 4 drives .... [16:39] good plan [16:39] I would limit swap to 1 x memory [16:39] I really don't bother with swap as a serious consideration, it's just a stop gap if I run out of RAM [16:39] RAM is so cheap now, it's just not worth the hassle [16:40] 16GB DDR3 is $100 [16:40] so, whatever is convenient extra space in your paritioning scheme, that's what I use for swap [16:41] qman__: with 8* Gb I don't really swap, but it doesn't cost much to setup. [16:46] qman__: I think I will split / & /common just because if at some future date I need to install a new opsys I can reformat if needed without affecting the data store. [16:49] qman__: any suggestions as to sizes, I was thinking /root 512Mb raid 1, 2Gb swap/drive, root (/) 160 GB raid 5, /common "the rest" raid 5. [16:50] qman__; any preference as to raid 5 or 6, raid 6 was not available on Centos so I have no experience with it. [17:01] or, going back to LVM, would I be better off I be better off setting up /root and swap and putting everthiong else under LVM [17:04] or doing what i should have done and read back over the post by qman__ stick to the KISS principle!!! [17:05] qman__: thanks for all the help, I am sure I will be back for more, have a good weekend! [17:11] johna, /root doesn't really need to be separate for any reason [17:12] unless you meant /boot [17:12] raid 6 adds additional parity at a very significant performance expense [17:12] I would suggest against it with four drives, it's only really worth it if you have 6+ and need two-disk failure protection [17:14] qman__: my mistake I meant /boot, OK, i will stick to raid 5 I might when funds permit add a spare to the raids, I believe that this is can be done. [17:14] yes, it's pretty easy to do [17:14] fdisk the new drive and then a single mdadm command [18:31] New bug: #811610 in mysql-5.1 (main) "package mysql-server-5.1 5.1.57-3.1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1" [Undecided,New] https://launchpad.net/bugs/811610 === ttx` is now known as ttx [21:10] ho can I get my slave bind servers to sync to the master automatically? === jeeves__ is now known as jeeves_moss [21:38] jeeves, how can you mess that up? [21:38] you just have to set axfr authorize, and notify [21:38] but then, I just find bind annoying, and dont use it === mcahornsirup_ is now known as mcahornsirup [23:06] Is there a problem with ubuntu and bridge networking? [23:06] http://pastebin.com/Yz4bJF8e [23:10] pdtpatrick1: how did you create the bridge? [23:11] e_t_, i installed bridge_utils and then manually edited network/interfaces [23:11] restarted networking but it craps out [23:12] which is funny because ifconfig shows virbr0 up and working just fine. [23:13] can you pastebin your interfaces file? [23:13] http://paste.ubuntu.com/645578/ [23:14] yes i know i did the static settings twice.. i was testing something out [23:15] crap .. i think it should be bridge_ports instead of bridge_port [23:16] yup that was it [23:17] how can i forward incoming traffic on some port and redirect it to a different port for processing on the same machine with iptables? [23:18] hmm, I don't make any bridges in /etc/network/interfaces, always do them differently [23:18] TheEvilPhoenix, REDIRECT [23:18] how do u usually do yours?

[23:18] TheEvilPhoenix: http://www.cyberciti.biz/faq/linux-port-redirection-with-iptables/ might help [23:19] pdtpatrick1, /etc/rc.local [23:19] can i see an exactly of your file ? [23:20] http://paste.ubuntu.com/645581/ [23:25] why u setting the mac addy.. i almost thought it was a broadcast at first. Curious [23:26] cause, I configured those bridges as if they are network switchs, they are not used on the system itself at all [23:26] your binding eth0 to yours, I don't [23:26] oh i c [23:26] thanks for that
