I'm experiencing a weird problem which I haven't been able to track down
for 8+ weeks now.
Situation is as follows: There is a nigthly backup from our main server
to a backup server. The server base directory is mounted there read-only
via NFS. Then we do something like this:
1. Duplicate the contents of yesterday's backup into
2. Rsync the server directory against that with the following command:
rsync -va --delete --timeout=180 --no-detach /server_ro/
[I've added the --timeout and --no-detach opitons for testing.]
Now, this usually works for a few days, then rsync hangs, leaving a
root 30729 30695 0 01:55 ? 00:00:02 rsync -va --delete
--timeout=180 --no-detach /server_ro/ /sicherungen/2007/02/02/01.41/
root 30730 30729 0 01:55 ? 00:00:00 [rsync] <defunct>
The last thing the log says is: "building file list ..."
Since the processes seem not to be killable, the only "remedy" is to
reboot the backup- server. Then it will work for a few days, until it
Installed are two SuSE 9.3 EE Linuxes, both fully updated. I'm not sure
which kernel versions, but both shóuld be 2.6.x I think. If that is
important please tell me how I could provide you with that information.
BTW it's "rsync version 2.6.3 protocol version 28"
I'm kind of lost here, and not exactly into Linux. I would appreciate
More information about the rsync
