Title:
System hangs apparently randomly when creating LVM snapshots
Status in linux package in Ubuntu:
Incomplete
Bug description:
We have several servers here which mount Ubuntu LTS Trusty Tahr 14.04. We use LVM snapshots to do backups during the night. Randomly (witha rate of 1 event every 10-12 days) the LVM snapshot creation runs in some problem. The server hangs and it must be rebooted hardly. No shell, no even any screen output, just a black screen, no ping, nothing. And Magic SysRq key doesn't help.
No logs are written either (I also tried redirect logs to another machine, just in case). This happens with different hardware, and different backup software. The only constant is LVM snapshots. Kernel is 3.13.0-49. We tried the 14.10 kernel (3.16.0-34), we had the same hangs, but this time we had something logged:
