BackupPC 3.1.0 on Debian, kernel is 2.6.32, filesystem is xfs. I have a BackupPC server that has twice now had the BackupPC server process spontaneously exit. It *did* shut down nicely, interestingly enough. The server log (/var/lib/backuppc/log/LOG) is this:
2011-08-11 08:00:01 Running 2 BackupPC_nightly jobs from 12..13 (out of 0..15) 2011-08-11 08:00:01 Running BackupPC_nightly -m 192 207 (pid=32271) 2011-08-11 08:00:01 Running BackupPC_nightly 208 223 (pid=32272) 2011-08-11 08:00:01 Next wakeup is 2011-08-11 09:00:00 2011-08-11 08:21:58 Finished full backup on host1.example.com 2011-08-11 09:00:01 Next wakeup is 2011-08-11 10:00:00 2011-08-11 09:51:47 Got signal PIPE... cleaning up 2011-08-11 12:22:30 Reading hosts file 2011-08-11 12:22:30 BackupPC started, pid 2195 2011-08-11 12:22:30 Running BackupPC_link host1.example.com (pid=2201) 2011-08-11 12:22:30 Next wakeup is 2011-08-11 13:00:00 2011-08-11 12:22:32 Finished host1.example.com (BackupPC_link host1.example.com) 2011-08-11 12:22:32 Running BackupPC_trashClean (pid=2205) I have BackupPC set to start its schedule at 8am; so it will do the BackupPC_nightly jobs when everyone is starting work, instead of in the middle of the night when the time is critically needed for doing backups. so that's why the log starts at 8am instead of the default midnight. It looks like there's no jobs running when the server exits; but obvously when it gets restarted (by me) it runs a BackupPC_link job on the host it was working on before it exited... so it's like the host 'hung' on doing something in the backup, exited (timeout of some sort?), then when restarted resumes where it left off and finishes all parts of the backup successfully. This isn't the per-host LOG (/var/lib/backuppc/pc/host1.example.com/LOG) or XferLOG (/var/lib/backuppc/pc/host1.example.com/LOG), so it's not obvious how to turn up the debug level or otherwise try to figure out what's going on here. It's happened twice, but I've never seen this host do it before. There's nothing in dmesg or syslog to indicate a problem. Only thing I can think of is that BackupPC is running into some sort of filesystem corruption that is causing it to fail out rather than risk corrupting it further. Upgrading this host to BackupPC 3.2.1 may be possible (need to get buy-in from some other admins before doing that); but before I do that I'm going to fsck the disks. I've never seen BackupPC do this before on any of the installations I admin and it's done it twice in a few days, so I'm suspecting hardware problems. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------------ Get a FREE DOWNLOAD! and learn more about uberSVN rich system, user administration capabilities and model configuration.
