Hi Luis,<br>
<br>
Thank you for your reply. Noatime is enabled:<br>
<font size="-1"><font face="Arial"><br>
/dev/drbd0 on /var/scans type ocfs2
(rw,_netdev,noatime,cluster_stack=pcmk)<br>
<br>
Without noatime performance was even worse!<br>
<br>
Cheers,<br>
<br>
Dirk<br>

I don't compare but if you send any stadistics about rsync
we can said more information.<br>
<br>
use rsync <b><strong>--stats<br>

I don't note difernt speed, but did you make a full

going at what speed?<br>

class="yiv2096855032gmail_quote">Hi All,<br>
<br>
I'm currently testing a OCFS2 set-up, and I'm having
issues with<br>
creating backups.<br>
<br>
I have a 2 node cluster, running OCFS2 on a dual
primary DRBD device.<br>
<br>
The file system is 3.7Tb of which 211 Gb is used:
about 1.5 million<br>
files in 95 directories.<br>
<br>
Everything works fine, except for the backups, which
are taking way more<br>
time than on 'regular' file systems.<br>
<br>
I'm using rsync for my backups. When I rsync the file
system above, this<br>
takes more than an hour, without any modifications to
the file system.<br>
<br>
Network / disk speed is good. I can rsync a 10 Gb file
from the OCFS2<br>
filesystem to the same backup server with just under
100 Mb/s.<br>
<br>
I know there is some penalty to be expected from a
clustered file<br>
system, but this is al lot. Rsyncing an ext3 file
system double the size<br>
(in Mb's and files) of this file system takes about
600 seconds...<br>
<br>
Has anybody some advice on a backup strategy for me?
Or some tuning tips?<br>
<br>
Thanks in advance,<br>
<br>
Dirk<br>
