| lotuspsychje | start here flowinho | 10:46 |
| flowinho | thank you lotuspsychje | 10:46 |
| lotuspsychje | flowinho: maybe if you share your specific purpose and services, volunteers can try to help you more specificly | 10:48 |
| lotuspsychje | flowinho: personally i also reccomend nmap your own ip aswell, to see how the outside world sees your server ports | 10:50 |
| vlm | is there any use of copying /etc/passwd and /etc/group file from / into a chroot when chrooting? | 12:15 |
| vlm | thing is,when i make a file using ssh like so : echo file|ssh user@chroot-host "cat > myfile" that file gets the proper owner regardless of presence of passwd and group file | 12:18 |

| locknet | trying to join a channel but hex cut my command | 15:47 |
| Maik | oh, ok :) | 15:50 |
| lordcirth_ | I just rebooted a prod 16.04 server after way too much uptime, and now lxc-* commands are all hanging, and no containers will start. Looking at htop, I see [lxc monitor] in "D" state. Help? | 17:34 |
| lordcirth_ | kill -9 of the hanging process kills the hanging command, but then the next command just hangs again | 17:37 |
| rbasak | D usually means blocked on I/O | 17:41 |
| rbasak | Do you have filesystem corruption or some kind of disk fault? | 17:42 |
| lordcirth_ | Not that I can see, but I will check again | 17:42 |
| rbasak | NFS hang? | 17:43 |
| lordcirth_ | rbasak, there are no IO errors in dmesg; some of the containers depend on cephfs, but not all, and the cephfs mount seems fine | 17:43 |
| lordcirth_ | (it's only used for homes, not /) | 17:44 |
| rbasak | I don't know then, sorry. | 17:44 |
| rbasak | It does seems like too much of a coincidence that you're using cephfs and you (superficially) appear to have something blocked on I/O though. | 17:45 |
| rbasak | I would exhaust that avenue first. | 17:45 |
| lordcirth_ | In the past, any cephfs error has been accompanied by tons of dmesg errors | 17:47 |
| lordcirth_ | I will tried to revert kernel but grub-reboot didn't work | 17:47 |
| lordcirth__ | rbasak, I rebooted with the cephfs mounts commented out and it still hangs. Trying now without nfs as well, but I'm not hopeful | 18:36 |

| lordcirth | Ok, so lxc-net is hanging on an iptables --wait command; but I have no idea why the iptables command is hanging. Maybe something else is hanging on the lock? | 19:45 |

| znf | strace it? | 20:00 |
| lordcirth_ | znf, was that to me? (sorry, I keep reconnecting) | 20:01 |
| znf | yes, strace the iptables? :) | 20:01 |
| lordcirth_ | I tried, it's just a wait4( that doesn't seem helpful... I don't use lxcbr0 anyway, so I am trying USE_LXC_BRIDGE="false" and rebooting | 20:03 |
| lordcirth_ | Most of the containers have started now... | 20:13 |
