I found what is going on. I have a bad logical volume - snapshot.
Excusme, but now I can not show output of lvs command, because I already deleted a bad volume. /dev/bigraid/tmp in a volume group. This confirmed by a log file: 2013-10-11 19:04:55.019+0000: 2103: error : virStorageBackendVolOpenCheckMode:1039 : cannot stat file '/dev/bigraid/tmp': No such file or directory 2013-10-11 19:04:55.029+0000: 2103: error : virCommandWait:2287 : internal error Child process (/sbin/vgchange -aln bigraid) unexpected exit status 5: Can't deactivate volume group "bigraid" with 11 open logical volume(s) But I still don't understand "How could this happen" in production server. When I big caution do a server setup. next goole translate, I'am tried: With these volumes, I came across earlier. But where they were taken I do not understand..... Excusme for a bug. I think that is a a my own mistake.
