I have been trying to get BackupPC implemented on my network and have
had reasonable success other than with one server.
Unfortunately, this is my primary file server!
Both the BackupPC machine and the file server are running Debian Linux
(Sarge) and I am using rsync for the backups. Filesystems on both sides
are xfs.
What happens is that when I try to back up the entire machine, the
backup runs a while and then hangs. It will eventually fail when it
hits the timeout, but looking at the time stamps on the log files, I can
see what time it quit doing any thing. There does not seem to be a
rhyme or reason to how long it runs (anywhere from 2-4 hours) or where
it is at in the directory tree when it fails. When I look at the
contents of the latest XferLOG.z, here is what I see at the end of it:
pool 670 1090/100 8704
everyone/V_Reagan/StoreRoom/Mombalan.doc
pool 670 1090/100 11264
everyone/V_Reagan/StoreRoom/Momlocat.doc
pool 670 1090/100 13312 everyone/V_Reagan/StoreRoom/Momm
Notice that it chops the name of the file in the last line and then just
quits updating anything.
rsync is still running on the client, but not producing anything.
I tried running a strace on rsync and here is what I saw:
) = 0 (Timeout)
select(1, [0], [], NULL, {60, 0}
(I've never used strace before, so don't really know what that means,
but I saw where someone suggest to run it for someone else.)
The partition that it hangs on is my /datadrive partition and here is
the stats on it:
/dev/sda3 581506104 336361120 245144984 58% /datadrive
So, I am using about 336GB out of 581GB available.
Underneath /datadrive, I have the following directories that I am
backing up:
home
public
shared
www
If I select /datadrive to backup in my client.pl file, it will hang.
If I select /datadrive and exclude a little, small directory from
underneath shared (holds about 3GB), it will succeed. (note that the
file in XferLog.z above that it stopped on is NOT in the directory that
I exclude when I do this)
Thinking size issues, I have, of course, increased the timeout, but that
hasn't helped. (besides that, it hangs long before it would ever time
out)
I also tried splitting things up and defining backups for
'/datadrive/home', '/datadrive/www', '/datadrive/public', and
'/datadrive/shared'. Thinking that would split things up and make the
file list smaller for the files being copied. It still hangs
on /datadrive/shared.
Does anyone have any ideas what might be happening here?
Any help is greatly appreciated!!!
