| keithzg | Huh, linux-headers-4.4.0-97 is taking *forever* to unpack on one of my server VMs. | 02:15 |
|---|---|---|
| sarnold | it's nearly 17k files | 02:17 |
| sarnold | what kind of iops do you have on that system? | 02:17 |
| keithzg | Not terribly great, since it's a VM running on an HDD. I'm just weirded out because other VMs on the same host didn't take nearly as long! | 02:18 |
| sarnold | hrm | 02:18 |
| keithzg | But yeah, fair enough, if any package is going to spend a long time unpacking this'd be the one, heh. | 02:19 |
| sarnold | check iostat -dmx1 or vmstat 1 or something similar to see if there's something doing a steady stream of sync writes to disk or similar? | 02:19 |
| sarnold | are there ioerror sin dmesg on host or guest? | 02:19 |
| sarnold | is the filesystem stored on an AF drive but with 512B sectors? | 02:20 |
| keithzg | Storage is qcow2, bus is virtio. Nothing showing up in dmesg. I must admit I don't know how to read vmstat, but iostat doesn't look *too* bad | 02:23 |
| keithzg | (on the host, guest doesn't have iostat installed and I can't do so right now, hah) | 02:24 |
| stokachu | stgraber: had a user see this with snap lxd stable http://paste.ubuntu.com/25782412/ | 02:25 |
| stokachu | stgraber: and http://paste.ubuntu.com/25782424/ | 02:25 |
| stgraber | stokachu: hmm, out of disk space maybe? that'd explain both of those | 02:26 |
| stokachu | bdx: ^ | 02:27 |
| bdx | I was running in a vm, its likely that could have been the issue ... I believe it had plenty of space though | 02:28 |
| stokachu | im guessing the vm isn't up any longer? | 02:30 |
| bdx | its not, I appologize | 02:32 |
| bdx | i have some scroll back though from when I was logged into it | 02:32 |
| keithzg | sarnold: Checking logical_block_size and physical_block_size in /sys/class/block/sda/queue/ (and sdb) on the host seems to confirm that they're old non-AF drives and formatted in the according 512B sectors. Hmm. I'm reminded by this that the drive in question is in fact a pair, using hardware RAID. Tempted to just blame it on that somehow :P | 02:32 |
| bdx | so, I removed system level lxd, and I still see it here http://paste.ubuntu.com/25782525/ | 02:33 |
| sarnold | keithzg: does the hardware controller have error logs available anywhere? | 02:33 |
| sarnold | keithzg: smart data? | 02:33 |
| bdx | I just have a feeling it was a cruft thing somehow, the system had lxd reconfigured quite a few times in and outside of the snap | 02:33 |
| keithzg | sarnold: This is very cheap commodity hardware, so I'd be surprised if the controller actually had accessible logs! For what it's worth smartcl hasn't logged any errors for either drive. | 02:35 |
| keithzg | (err, I should say, smartctl doesn't report that any smart errors have been logged on either drive) | 02:36 |
| sarnold | keithzg: hrm, somehow this is a bit unsatisfying :) it feels like it ought to be possible to nail down what's going on. | 02:36 |
| sarnold | I don't remember spinning metal drives a being -that- slow, somehow we survived back in the day :) | 02:37 |
| keithzg | hehe | 02:37 |
| keithzg | sarnold: No kidding! I'm almost tempted to just cancel the operation, install iostat, and start it up again :P | 02:37 |
| sarnold | keithzg: wait the damn thing is still going?? | 02:38 |
| keithzg | sarnold: Haha actually inbetween me saying that and you replying, it finally got past that package! | 02:38 |
| sarnold | hehe | 02:38 |
| sarnold | 19:15:09 to 19:37:44. 12.5 files per second. that sounds slow. | 02:40 |
| sarnold | and presumably you only complained on irc after it'd been going on for a little while already. | 02:40 |
| keithzg | Yeah, I checked on it a few times and eventually went "seriously, *still*?" and only then piped up here | 02:41 |
| keithzg | Clearly I'm going to have to keep a watchful eye on this guest and its host . . . | 02:42 |

| FMan | hi | 13:52 |
| drab | hi, is it still a pipedream to have a simple solution to monitoring what's going on on the network? | 15:49 |
| drab | way back doing it "right" meant to set up cflow/netflow and it was a pita just to get through the standards | 15:49 |
| drab | any chance it got easier? | 15:50 |
| drab | the alternative used to be cacti, but that only really gives you a sense of traffic per port, not really the type of traffic like netflow does (well at least you get ip + port tuples on each switch port) | 15:51 |

| orogor | hi | 19:37 |
| orogor | anyone would know why sudo wouldn t work after upgrade to 17.10 ? | 19:37 |
| orogor | it just hang there after typing a good password | 19:38 |
| gunix | iface bond0.10 inet manual | 21:20 |
| gunix | what does .10 mean? | 21:20 |
| gunix | oh, vlan tag | 21:21 |
| Blueking | apt autoremove doesn't clean latest and need to check what version ubuntu are currently running before clean/remove stuff in /boot | 21:56 |
