sarnold | jordanrandles: are there any errors or warnings logged in any log files that look relevant? | 00:00 |
---|---|---|
jordanrandles | sarnold: I wouldnt know, I dont have access to the log files. The server computer is in my server room but it wont let me input anything using a keyboard as if the USBs are not working but they are fine. Its ever since I 'tried' setting up openvpn | 00:02 |
jordanrandles | Its not taking any input from the keyboard | 00:12 |
jordanrandles | it seems like the server only does this using Linux 3.16 | 00:23 |
jordanrandles | But I just booted using Linux 3.13 and it works fine. Is there any way to make the server always boot into this version? | 00:24 |
sarnold | you could edit your grub menu to only include the 3.13 kernel, or uninstall the 3.16 kernels.. | 00:26 |
sarnold | but more likely that's just a symptom of something else that didn't work, perhaps the initrd images weren't properly created for the 3.16 kernels.. | 00:27 |
jordanrandles | So what do I do to fix this? | 00:28 |
jordanrandles | Or find out if that is the problem? | 00:28 |

jvwjgames | No internet from my server need help | 02:21 |
jvwjgames | I had to go earlier and was not able to fix the issue | 02:21 |
sarnold | jvwjgames: start with the basics: make sure ethernet wires are fully seated, not wrapped around flourescant ballasts, etc.; make sure everything in the path is properly plugged in; check dmesg and log files for errors | 02:23 |
sarnold | jvwjgames: make sure you've got good link light from both NICs; replace endpoints if you need to | 02:23 |
sarnold | jvwjgames: check ip addr show and ip route show output on both hosts, make sure they make sense | 02:24 |
jvwjgames | Whenever I ping or traceroute I get interface IP as reply regardless of what the destination is | 02:24 |
sarnold | jvwjgames: start with simple protocols, ping to IPs, then nc to tcp and udp ports; if those work but larger packets don't work, maybe pmtu settings are broken? | 02:24 |
jvwjgames | See my post above ^^ | 02:25 |
TJ- | jvwjgames: is the IP address assigned by DHCP, or manually set? | 02:27 |
jvwjgames | Manually | 02:27 |
jvwjgames | And I do know it's right cause I tested it before | 02:28 |
sarnold | jvwjgames: does "ip addr show" and "ip route show" look correct on both hosts? | 02:28 |
TJ- | jvwjgames: can you pastebin (transfer via USB maybe) the "/etc/network/interfaces" file if that is where you've defined the interface | 02:28 |
jvwjgames | Ok | 02:29 |

lordievader | Ok, where is the directory defined? | 07:24 |
lordievader | That is where I have configured the basic auth. | 07:25 |
neurotus | /var/www/html/poly | 07:26 |
lordievader | neurotus: That is the directory, not apache's definition of it. | 07:28 |
lordievader | Those are usually somewhere in /etc/apache2/ | 07:28 |
neurotus | darn, now the whole /var/www/html is protected and doesnt ask for password and not only the html/poly folder | 07:39 |
lordievader | How did you configure the basic auth? | 07:41 |
neurotus | i get 403 FORBIDDEN and it doest not ask for a password | 07:45 |
lordievader | How did you configure the basic auth? | 07:46 |
neurotus | lordievader: i just put .htaccess in /var/www/html/directory and put in apache2.conf AllowOverride All | 07:46 |
lordievader | So you didn't configure anything? | 07:46 |
neurotus | and did .htpasswd in directory | 07:46 |

nch | hello, I moved the content of / of my mdadm raid lvm volume to a new hard drive partition and installed grub manually on the new hard drive, the system is running but I cant start several services and when I try to use tab for autocompletion in directory navigation it tells me: -bash: cannot create temp file for here-document: Permission denied | 18:40 |
nch | what is wrong here? The syslog file is also clear :\ | 18:41 |
sarnold | nch: feels like you might have incorrect permissions on a directory somewhere | 18:42 |
sarnold | nch: /tmp feels quite likely; try ls -ld /tmp | 18:42 |
nch | sarnold: it gives me that: "drwxr-xr-t 5 1777 root 4096 Sep 25 20:40 tmp" | 18:42 |
sarnold | aha, that's probably it ;) | 18:43 |
sarnold | nch: chown 0:0 /tmp ; chmod 1777 /tmp ; check it again | 18:43 |
nch | now it gives me that: drwxrwxrwt 5 root root 4096 Sep 25 20:45 tmp | 18:45 |
nch | but it is still not working | 18:46 |
nch | sarnold: any other idea why syslog gets no entries and my apps are not starting due to permission errors I guess? | 18:46 |
sarnold | nch: hmm, you may have more permissions problems; I was hoping that'd be the only one | 18:47 |
sarnold | I don't know off-hand any way to automate looking for them on ubuntu system | 18:48 |
nch | sanold: but why? I just copied the whole content of / with cp :\ | 18:48 |
=== wmp is now known as Guest36842 | ||
sarnold | nch: cp doesn't copy permissions and owner and group information unless you request it specifically with e.g. cp -a or fiddle with --preserve ... | 18:49 |
nch | well shit -.- | 18:49 |
sarnold | nch: if you copied a whole system withuot cp -a you may find it easier to start over | 18:49 |
=== bitbyte_ is now known as bitbyte | ||
nch | Ok now I dont have the original / is there any way to change the permissions for the whole system? | 18:50 |
sarnold | nch: another possibility is to fix errors one at a time until you get a point tha tyou can run apt-get install --reinstall ... on every package on the system | 18:50 |
nch | sarnold: well shit | 18:52 |
sarnold | nch: that sounds like a pretty fair summary of the situation :) | 18:52 |
nch | sarnold: well yes, I have no plan what to do now :\ | 18:53 |
sarnold | nch: I'm actually surprised it booted far enough for you to get to a shell that lets you solve problems. it could be worse. | 18:53 |
sarnold | nch: but there's no denyuing that fixing this will be painful. | 18:54 |
=== TheEternalAbyss is now known as Guest44026 | ||
nch | sarnold: yes the boot was no problem, also samba and its network shares are working fine but the rest not^^ | 18:54 |

nch | nch@media:/$ ls -ld /etc drwxr-xr-x 112 root root 4096 Sep 25 20:03 /etc | 18:56 |

RoyK | Slugs_: first of all, why partitions? | 20:17 |
Slugs_ | Hi RoyK | 20:18 |
Slugs_ | well, that’s one of the guides i followed online | 20:18 |
Slugs_ | don | 20:18 |
Slugs_ | i can delete the partitions | 20:18 |
RoyK | Slugs_: and --level=stripe - is that like russian roulette | 20:19 |
Slugs_ | lol | 20:19 |
Slugs_ | yeah i know you and i discussed this, i didn’t care about data loss | 20:19 |
jrwren | partitions are good. | 20:20 |
RoyK | jrwren: nah | 20:20 |
RoyK | jrwren: using raw disks is better | 20:20 |
jrwren | why? | 20:20 |
RoyK | jrwren: helps things when you want to extend | 20:20 |
jrwren | how? | 20:20 |
RoyK | jrwren: why do you want those partitions anyway? | 20:20 |
jrwren | need everything to start offset a few MB so I can keep bootsectors at start of disk. | 20:20 |
RoyK | jrwren: hey! I have a partition! it's 2TB! | 20:21 |
jrwren | right, 2TB minus 2MB so that I can boot from any disk in the set | 20:21 |
RoyK | jrwren: don't use the OS disks for data | 20:21 |
jrwren | why? | 20:21 |
RoyK | jrwren: use data disks for data, use separate OS disks | 20:21 |
jrwren | why? | 20:21 |
RoyK | jrwren: because it makes things easier | 20:21 |
RoyK | jrwren: recovery etc | 20:21 |
jrwren | how? | 20:22 |
Slugs_ | lol | 20:22 |
RoyK | jrwren: but then, I've only worked with this for 20+ years :P | 20:22 |
jrwren | could it be the same year 20 times? :p | 20:22 |
RoyK | jrwren: take a good advice, please | 20:22 |
jrwren | why? | 20:22 |
RoyK | jrwren: just google it | 20:23 |
jrwren | ok. | 20:23 |
* RoyK is not in a mood of teaching idiots how to ignore advices | 20:23 | |
Slugs_ | ok so i have 4 disks, all 4TB a peice | 20:23 |
Slugs_ | used only for data | 20:23 |
RoyK | Slugs_: why raid0 | 20:23 |
Slugs_ | i was doing it for speed. | 20:24 |
Slugs_ | but i think yiou migfht have said not really good performance with 4 TB disks anyway | 20:24 |
RoyK | Slugs_: you'll get the same speed of a raid5 with 3 drives as a raid0 of 4 drives, sequencially | 20:24 |
Slugs_ | what do i do with the other disk? | 20:24 |
RoyK | Slugs_: and it saves a day or three if you use raid5 | 20:24 |
RoyK | when that one drive dies | 20:25 |
RoyK | and it will | 20:25 |
Slugs_ | yeah | 20:25 |
Slugs_ | ok | 20:25 |
Slugs_ | what do i do with the 4th disk though? | 20:25 |
jrwren | Slugs_: alternatively, you can test it both ways and measure for your specific application and use which works best for you. | 20:25 |
Slugs_ | yeah makes sense | 20:26 |
RoyK | Slugs_: just use a single drive, even a thumb drive, for the root | 20:26 |
RoyK | Slugs_: then use the 4TB things in raid5 | 20:26 |
Slugs_ | yeah i have 1 500 gb for root | 20:26 |
Slugs_ | and 4, 4TB drives for data | 20:26 |
RoyK | nice | 20:26 |
RoyK | Slugs_: then create a raid5 on those | 20:27 |
RoyK | Slugs_: you can change to raid0 later if you want | 20:27 |
jrwren | Slugs_: so your 1 500GB is /dev/sde ? | 20:27 |
Slugs_ | ok so i can do raid5 on 4 disks then | 20:27 |
Slugs_ | jrwren: yes exactly | 20:27 |
RoyK | Slugs_: just use raid5 on those, directly on the disks | 20:27 |
RoyK | Slugs_: no partitions needed | 20:27 |
jrwren | Slugs_: good. just making sure it isn't sda. :) | 20:27 |
Slugs_ | how did you know thaT? | 20:28 |
RoyK | lsscsi? | 20:28 |
RoyK | jrwren: it doesn't matter if it it's called sda or not | 20:28 |
jrwren | RoyK: it would matter if the 500GB disk is sda, and he just ran mdadm passing sda1 as a partition to use. | 20:28 |
RoyK | jrwren: it wouldn't work | 20:29 |
jrwren | Slugs_: good luck. | 20:29 |
jrwren | RoyK: exactly. and Slugs_ said, 'this command doesn't work" | 20:29 |
jrwren | specifically /dev/sda1 in use. | 20:29 |

Slugs_ | i was testing out speed, it wasn’t a final configuration | 20:36 |
Slugs_ | just testing | 20:36 |
Slugs_ | not planning on using it… | 20:36 |
jrwren | Slugs_: i'll assume it is not production and not call you names :) | 20:36 |
Slugs_ | ;) | 20:36 |
Slugs_ | thanks | 20:36 |
RoyK | what does /proc/mdstat have to say? | 20:36 |
RoyK | or pvs | 20:36 |
Slugs_ | Personalities : | 20:37 |
Slugs_ | unused devices: <none> | 20:37 |
Slugs_ | PV VG Fmt Attr PSize PFree | 20:37 |
Slugs_ | /dev/sde5 openstack-vg lvm2 a-- 465.52g 52.00m | 20:37 |
RoyK | ok | 20:37 |
RoyK | can fdisk access /dev/sda? | 20:37 |
Slugs_ | yes | 20:37 |
RoyK | and delete that partition? | 20:37 |
Slugs_ | WARNING: Re-reading the partition table failed with error 25: Inappropriate ioctl for device. | 20:38 |
Slugs_ | The kernel still uses the old table. The new table will be used at | 20:38 |
Slugs_ | the next reboot or after you run partprobe(8) or kpartx(8) | 20:38 |
Slugs_ | then i ran partprobe | 20:38 |
Slugs_ | didn’t give any errors, but i guess something is still confused | 20:38 |
RoyK | remove the partition and reboot | 20:39 |
Slugs_ | ok | 20:39 |
Slugs_ | rebooting .... | 20:39 |
RoyK | ... | 20:43 |
Slugs_ | it’s back up | 20:43 |
Slugs_ | oh boy | 20:44 |
RoyK | pastebin lsblk again | 20:44 |
Slugs_ | ok | 20:44 |
RoyK | or did mdadm --create work? | 20:44 |
Slugs_ | http://pastebin.com/aECe1zwt | 20:44 |
Slugs_ | no the drive names changed | 20:44 |
Slugs_ | good thing i didn’t just run it | 20:45 |
Slugs_ | well like you said it might not have letme | 20:45 |
Slugs_ | let me* | 20:45 |
RoyK | ok, so mdadm --create /dev/md0 --raid-devices=4 --level=5 /dev/sd{b..e} | 20:45 |
RoyK | dev names change | 20:46 |
RoyK | md uses UUIDs to determine which drives are what | 20:46 |
Slugs_ | it worked | 20:46 |
RoyK | then vgcreate | 20:47 |
RoyK | and lvcreate | 20:47 |
RoyK | and put a filesystem on top of the lv | 20:47 |
Slugs_ | the guide said , assemble | 20:47 |
Slugs_ | so… this is diff | 20:47 |
* Slugs_ is looking up vgcreate and lvcreate | 20:47 | |
RoyK | assemble is what you do when things mess up | 20:47 |
Slugs_ | i see | 20:48 |
RoyK | apt-get install lvm2 | 20:48 |
RoyK | but that's probably installed already | 20:48 |
RoyK | pvcreate /dev/md0 | 20:48 |
Slugs_ | it is | 20:48 |
RoyK | vgcreate mysuperdata /dev/md0 | 20:48 |
RoyK | lvcreate -l 100%FREE veryimportantdata mysuperdata | 20:49 |
RoyK | or something about that | 20:49 |
jrwren | Slugs_: what guide? | 20:50 |
Slugs_ | one that sucks i guess | 20:50 |
Slugs_ | https://help.ubuntu.com/community/Installation/SoftwareRAID | 20:50 |
RoyK | Slugs_: did you create the pv or vg? | 20:51 |
Slugs_ | yes RoyK just working on the lvcreate and seeing what that did | 20:51 |
RoyK | it creates a logical volume | 20:52 |
jrwren | Slugs_: server guide has this: https://help.ubuntu.com/lts/serverguide/advanced-installation.html for future reference | 20:52 |
RoyK | one you need for putting a fs on | 20:52 |
Slugs_ | ok | 20:52 |
Slugs_ | jrwren: thank you | 20:52 |
RoyK | so after creating the lv | 20:52 |
RoyK | what did you name it? what did you name the vg? | 20:52 |
Slugs_ | vg = data | 20:53 |
Slugs_ | what’s the veryimportantdata part? | 20:53 |
RoyK | just a name | 20:53 |
Slugs_ | descrioption/? | 20:53 |
Slugs_ | ok | 20:53 |
RoyK | you can rename it or remove it | 20:54 |
Slugs_ | hmm | 20:55 |
Slugs_ | root@openstack:/home/openstack# lvcreate -l 100%FREE /dev/md0 data | 20:55 |
RoyK | lvs | 20:55 |
Slugs_ | ? | 20:55 |
Slugs_ | Volume group "md0" not found | 20:55 |
RoyK | if you didn't give it a name, it'll be named automatically | 20:55 |
RoyK | erm | 20:56 |
Slugs_ | oh i see | 20:56 |
Slugs_ | Logical volume "lvol0" created | 20:56 |
RoyK | lvcreate -n myname -l 100%FREE data | 20:56 |
Slugs_ | lvol0 data -wi-a---- 10.92t | 20:56 |
Slugs_ | i can rename it then,,, ok | 20:56 |
RoyK | lvrename | 20:56 |
Slugs_ | what’s the path for the logical volume | 20:58 |
Slugs_ | root@openstack:/home/openstack# lvrename lvol0 UMS | 20:58 |
Slugs_ | Path required for Logical Volume "lvol0" | 20:58 |
RoyK | Slugs_: from the manual lvrename /dev/vg02/lvold vg02/lvnew | 20:58 |
Slugs_ | ok got it | 20:59 |
Slugs_ | now i guess all i need is a filesystem on it? | 21:00 |
RoyK | then put a filesystem on it | 21:00 |
RoyK | I'd suggest xfs for most use | 21:00 |
RoyK | ext4 isn't too good on large things | 21:00 |
RoyK | I spent eight hours waiting for a 8TB ext4 filesystem doing fsck two days back | 21:00 |
Slugs_ | mkfs.xfs /dev/mapper/data-lvol0 | 21:00 |
Slugs_ | oh my | 21:01 |
RoyK | mhm | 21:01 |
Slugs_ | ok | 21:01 |
RoyK | then add to /etc/fstab | 21:01 |
RoyK | mount -a | 21:01 |
RoyK | the normal things | 21:01 |
Slugs_ | ive seen so many different posts on what to put in your fstab file | 21:02 |
qman__ | I personally have misgivings about xfs but I admit it's from anecdotal experiences | 21:02 |
RoyK | Slugs_: /dev/mapper/data-lvol0 /mountpoint xfs defaults 0 0 | 21:03 |
RoyK | qman__: probably anectdotal | 21:03 |
ianorlyn | I think the unable to shrink it makes it not be defualt for lots of desktop but not really sure why most servers you would want to shrink a partition that much | 21:04 |
ianorlyn | although sparse files is a nice feature | 21:04 |
qman__ | I've lost data several times with xfs, never with ext3 or ext4 | 21:04 |
RoyK | ianorlyn: most filesystems won't be shrunk | 21:04 |
Slugs_ | RoyK: is mount -a supposed to just automuont this new fs? | 21:04 |
RoyK | Slugs_: yes | 21:04 |
sarnold | the only filesystem I've seen shrink was FAT, via the fips tool. scary as hell. | 21:04 |
Slugs_ | nothing appears to happen when i type df, or is it not suppoosed to show up there/ | 21:05 |
RoyK | Slugs_: but that data-lvol0 may be different when you changed the name of the lv | 21:05 |
Slugs_ | im not going to bother changing it | 21:05 |
jrwren | how is the sparse files feature different in xfs v. ext4? | 21:05 |
RoyK | Slugs_: pastebin lvs | 21:05 |
RoyK | jrwren: hardly | 21:06 |
Slugs_ | http://pastebin.com/eFjJA9zy | 21:06 |
jrwren | i've shrunk ext4 many times. it works nicely. | 21:07 |
sarnold | jrwren: that's even scarier :) | 21:07 |
RoyK | Slugs_: so /dev/data/lvol0 /data xfs defaults 0 0 | 21:07 |
Slugs_ | ok | 21:07 |
qman__ | I've also run into the problem with xfs where you can't add any more files even though there's more space because the first block thing is full | 21:07 |
RoyK | Slugs_: just create /data first | 21:08 |
qman__ | I forget what it's called | 21:08 |
jrwren | sarnold: i should have been more scared than I was. i shrunk without backup! ;] | 21:08 |
sarnold | jrwren: brave brave brave :) hehe | 21:08 |
RoyK | qman__: I have this neat 25TB filesystem on xfs - works well | 21:09 |
qman__ | I've shrunk ext file systems without problems too | 21:09 |
Slugs_ | RoyK: Thank you! | 21:09 |
RoyK | Slugs_: ;) | 21:09 |
Slugs_ | 11 TB | 21:09 |
ianorlyn | although the man pages for xfsprogs and e2fsprogs contain some nice looking options | 21:09 |
qman__ | RoyK: this was a 110tb fs that was expanded | 21:09 |
RoyK | qman__: oops | 21:09 |
qman__ | Yeah, customer made some unwise choices, nothing I could do by the time I got to it | 21:10 |
RoyK | qman__: a restore from tape to that would take some time | 21:10 |
jrwren | sarnold: i'm too stupid to be brave :) truthful, its my data, I considered the risk of doing it with backup and not, and made a decision | 21:10 |
qman__ | They let it fill 100% then expanded | 21:10 |
RoyK | Slugs_: does it work? | 21:11 |
ianorlyn | worst backup solution ever raid 0 tape drives | 21:11 |
Slugs_ | RoyK: yes | 21:11 |
Slugs_ | I guess it’s initializing or something | 21:11 |
Slugs_ | i did /proc/mdstat | 21:11 |
Slugs_ | and it appears to be initializing i guess | 21:11 |
RoyK | Slugs_: give it a reboot to see if it's coming up correctly | 21:11 |
Slugs_ | [>....................] recovery = 4.2% (167079192/3906887168) finish=491.0min speed=126940K/sec | 21:12 |
Slugs_ | what about this... | 21:12 |
=== PrudentMav is now known as PrudentMav[away] | ||
RoyK | Slugs_: it needs to initiate the raid | 21:12 |
RoyK | or initialise | 21:12 |
Slugs_ | should i reboot now or wait | 21:12 |
RoyK | wait | 21:12 |
Slugs_ | ok | 21:12 |
qman__ | Makes no difference really | 21:12 |
qman__ | If you reboot it will resume | 21:12 |
Slugs_ | oh, not start over? | 21:13 |
=== PrudentMav[away] is now known as PrudentMav | ||
RoyK | qman__: does ubuntu boot with degraded now? | 21:13 |
Slugs_ | i read a post it did | 21:13 |
qman__ | Oh, that might be a headache, forgot about that | 21:13 |
=== PrudentMav is now known as PrudentMav[away] | ||
=== PrudentMav[away] is now known as PrudentMav | ||
RoyK | Slugs_: dpkg-reconfigure mdraid | 21:14 |
RoyK | Slugs_: and choose boot degraded | 21:14 |
Slugs_ | it’s not a boot drive though, is that ok? | 21:14 |
RoyK | Slugs_: some idiots have chosen ubuntu not to boot with degraded raid | 21:15 |
RoyK | that's what raid is for for fscks sake | 21:15 |
Slugs_ | wow, so if your raid becomes degraded……. you can’t boot of your non raid boot drive? | 21:15 |
Slugs_ | off* | 21:15 |
qman__ | Because it's "safer" for those who don't monitor their systems | 21:15 |
RoyK | qman__: heh | 21:16 |
qman__ | Forces them to fix it rather than let it die | 21:16 |
RoyK | qman__: doesn't make sense | 21:16 |
Slugs_ | am i right and what your saying? | 21:16 |
qman__ | Yeah, I don't agree with it either, but that's the reasoning | 21:16 |
RoyK | qman__: a system that lets you do an rm -f anywhere and not letting the system boot without a drive in a raid? | 21:17 |
qman__ | I also don't agree with grub halting on failure to boot | 21:17 |
qman__ | Causing lots of annoying unnecessary dispatches that | 21:17 |
RoyK | Slugs_: just reconfigure that and try a reboot | 21:18 |
Slugs_ | http://pastebin.com/EwqXCWMB | 21:18 |
RoyK | Slugs_: it'll show how well the system works with a failed drive | 21:18 |
qman__ | The power flickering a couple times shouldn't stop the system from booting when it comes back | 21:18 |
RoyK | Slugs_: that's the data storage, not your boot device | 21:19 |
Slugs_ | ok | 21:19 |
RoyK | Slugs_: | 21:19 |
Slugs_ | ok rebooting | 21:20 |
Slugs_ | down... | 21:20 |
RoyK | damn - home server went down :( | 21:22 |
Slugs_ | back up RoyK | 21:29 |
Slugs_ | df -h | 21:29 |
Slugs_ | looks like it picked up where it left off | 21:29 |
Slugs_ | so if i wouldnt have installed dmraid, and a drive when down i would not be able to boot/> | 21:30 |
Slugs_ | ? | 21:30 |
=== markthomas|away is now known as markthomas | ||
Slugs_ | i have to write all this down... | 21:30 |
qman__ | I use partitions not only because of the boot feature, but also to prevent data loss in the event of a misguided partitioning tool or grub install, and also because I've run into instances where one type of hard drive is just slightly larger or smaller than another | 21:38 |
qman__ | A 2mb buffer can save you when the replacement disk you bought is a block smaller than the one it's replacing | 21:39 |
qman__ | It also makes it apparent what's on the disk in a recovery scenario | 21:41 |
