<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>
