| hallyn | zul: meh, i think my libvirt preinst/postinst bits to handle starting libvirt-guests is wrong altogether. | 02:35 |
| hallyn | zul: i think it needs to drop the preinst bit ,and just unconditionally start libvirt-guests. which also has wrong name for libvirtd service. | 02:36 |
| lordievader | Good morning. | 07:36 |

| teward | general question: I have a computer upon which I installed Ubuntu Server 14.04.3. /etc/network/interfaces has `allow-hotplug eth0` and `iface eth0 inet dhcp` in it, but on boot it doesn't get configuration done for the network / IP. Manual execution of `dhclient` makes it negotiate correctly. | 14:15 |
| teward | any ideas of diagnosing? | 14:15 |
| lordievader | Check the logs. | 14:20 |
| teward | which logs :P | 14:21 |
| * teward yawns | 14:21 | |
| lordievader | dmesg, messages, syslog, etc | 14:22 |
| teward | mmmm | 14:24 |
| teward | nothing informative in dmesg, syslog. except that pre-start terminated with status 1, and post-stop terminated with 100 | 14:25 |
| teward | kernel earlier on also complains it terminated with status 1 twice | 14:25 |
| teward | but it doesn't appear informative of any specifics :/ | 14:25 |
| lordievader | Pre/post start of what? | 14:26 |
| lordievader | Networking? | 14:26 |
| teward | mhm | 14:27 |
| * teward yawns | 14:27 | |
| teward | sorry, i'm still waking up >.< | 14:27 |
| lordievader | Is that a yes? | 14:27 |
| teward | yes, it is | 14:27 |
| lordievader | teward: There is your problem. | 14:27 |
| teward | lordievader: uninformative error codes are uninformative. any idea where they're documented? | 14:28 |
| lordievader | Err, no idea. | 14:29 |
| lordievader | Upstart keeps logs though. | 14:29 |
| teward | upstart's logs were helpful | 14:30 |
| teward | apparently it said invalid option placement. | 14:30 |
| teward | looking at the interfaces file, i had to open it in a different editor, but it found rogue ascii | 14:30 |
| teward | that answers the problem xD | 14:30 |
| teward | (neither nano nor vi nor vim showed the ascii. hex editor found it ;P) | 14:30 |
| TJ- | teward: i usually find 'less' is good for spotting those random control codes, unless using 'less -r' | 14:45 |
| teward | ,,, | 14:49 |
| teward | mmm* | 14:49 |
| teward | yeah, well, meh | 14:49 |
| teward | found it, fixed it, problem solved :) | 14:49 |

| tgm4883 | Trying to mount a hosts directory into an lxc container using the command listed as an example when running lxc config (which is "lxc config device add container1 mntdir disk source=/share/c1 path=opt"). I get no errors on the command line, but nothing in that folder is present when I do an ls from inside the container. Is there something else that needs to | 17:03 |
| tgm4883 | be done? | 17:03 |
| tgm4883 | Hmm, apparently it has to be stopped to add it | 17:12 |
| hallyn | zul: smb: does http://paste.ubuntu.com/12594504/ make sense to you? | 18:50 |
| zul | hallyn: oooks ok to me | 19:02 |
| hallyn | zul: does what i'm saying and doing make sense? | 19:03 |
| zul | yeah | 19:03 |
| hallyn | cool, thanks | 19:05 |
| hallyn | i'll push in a bit when i feel more couragious | 19:05 |

| Karunamon | hi folks, does anyone in here know anything enough about mdraid to explain why it can't see a mirrored drive from another system? | 21:12 |
| lordievader | Karunamon: Have you assembled them? | 21:14 |
| patdk-lap | have you put the disks from the other system into this one? | 21:17 |
| Karunamon | the one disk, yes | 21:17 |
| Karunamon | the other one is toast | 21:17 |
| Karunamon | if i do an mdadm -E /dev/sdb1, it sees the drive as part of an array, but the problem i'm having is actually getting the cursed thing mounted | 21:18 |
| lordievader | Karunamon: Probably since the other disk is not found it wont assemble it automatically, you have to do that manually. | 21:20 |
| Karunamon | an --assemble --scan shows me "/dev/sdb1 has wrong uuid" | 21:20 |
| TJ- | Karunamon: does the current system also have md arrays? If so, does the metadata on both have the same device node name (e.g. md0) ? | 21:21 |
| Karunamon | TJ-,no other arrays on the system | 21:21 |
| Karunamon | hm, there it goes. Apparently an earlier command had dumped a line for a non existent array into mdadm.conf | 21:25 |
| Karunamon | cleared that, --assemble --scan, and we're good | 21:25 |
| Karunamon | of course now the filesystem does not want to mount | 21:25 |
| Karunamon | so it's XFS.. (this much I know from memory), but it can't be mounted because it's trying to read beyond the end of the disk? | 21:33 |
| Karunamon | 262144 (sectors? blocks?) beyond the end | 21:36 |
| TJ- | Are you sure the original array was only RAID-1 ? | 21:39 |
| Karunamon | 100% positive. There were four drives in the old system, two RAID1 sets | 21:39 |
| bekks | Two raid1 sets or one raid10 set? | 21:40 |
| Karunamon | two raid1 sets (one was for the system, the other was for bulk storage) | 21:40 |
| TJ- | Karunamon: OK, it could be a HPA (Host Protected Area) issue I suppose. | 21:40 |
| Karunamon | i'm also sure this is the case since I set it up that way because there were two 500g drives and two 250g drives :) | 21:40 |
| Karunamon | oh boy.. this got complicated, then | 21:41 |
| Karunamon | because the drive is being accessed via a raw device mapping on an esx server connected as a single disk logical device on a HP raid controller >_< | 21:41 |
| TJ- | Karunamon: is the raw drive partitioned, or pure MD without a partition table? | 21:41 |
| Karunamon | it's partitioned, the first partition is the mdraid device | 21:42 |
| TJ- | Karunamon: which metadata version is the MD using (that affects where the metadata is in the underlying partition) | 21:45 |
| Karunamon | 1.2 | 21:45 |
| TJ- | Did the error message about reading beyond end of device come from the kernel log? Can you show the exact message (and any surrounding messages that are relevant) ? | 21:47 |
| Karunamon | It did come from the kernel (per syslog), but what's there is pretty scant | 21:49 |
| Karunamon | lemme paste it | 21:49 |
| Karunamon | https://gist.github.com/4052b9be877070e2a5b7 | 21:51 |
| Karunamon | the first one was during an attempt to mount, the second was during an xfs_repair attempt | 21:52 |
| TJ- | Karunamon: "capacity change from 0 to 499837108224" matches "limit=986244352" (in 512-byte sectors). | 21:54 |
| Karunamon | TJ-: so it's mdadm who has the wrong idea as to the size this thing should be | 21:55 |
| TJ- | Karunamon: what does "hdparm -N /dev/sdX" report about HPA? | 21:55 |
| Karunamon | max sectors = 0/1, HPA is enabled | 21:56 |
| TJ- | Karunamon: aha, so HPA = yes, but "0/1" ... that's not right! | 21:56 |
| Karunamon | there could be some strangeness because of the convoluted way this drive is mounted | 21:56 |
| TJ- | Karunamon: is it on a USB controller? | 21:57 |
| Karunamon | Worse. So this system is a VM, it's using a raw device mapping in ESXi to access the drive, itself connected to a raid controller as a single disk device | 21:57 |
| Karunamon | and before you ask: it's a SAS drive, and I don't have any other gear onhand to read those | 21:58 |
| Karunamon | so some quick searching.. this sounds like an automatic HPA unlocking thing that ubuntu had some issues with a while back? | 22:00 |
| === Lcawte is now known as Lcawte|Away | ||
| TJ- | Karunamon: hmmm, can you use hdparm from the host? | 22:00 |
| Karunamon | it was unlocked on the previous system, and not here, so the end of the drive is seemingly missing? | 22:00 |
| Karunamon | not on the host unfortunately | 22:01 |
| TJ- | Karunamon: Yes. There's a trick many sysadmins uses to avoid this. When creating an MD device not allocating all the raw device, to allow HPA to be on/off without a problem. Not much help now of course :) | 22:01 |
| TJ- | Karunamon: what does this report? "hdparm --dco-identify /dev/sdX" ? | 22:02 |
| Karunamon | https://gist.github.com/16e60ab28ad2f02c8663 | 22:12 |
| Karunamon | @TJ- | 22:12 |
| Karunamon | I'm thinking I could bring this drive into work if there's something to mutter at hdparm to get that hpa disabled | 22:13 |
| Karunamon | and get it plugged into real hardware | 22:13 |
| TJ- | Karunamon: looks like ESXi is getting in the way | 22:14 |
