<div class="gmail_quote"><div>Hi Julien,</div><div><br></div><div>answers inline.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div><p><span lang="fr"><font size="2" face="Arial">I've just installed a new glusterfs architecture to replicate my storage tank.</font></span>
<br><span lang="fr"><font size="2" face="Arial">We have two servers with two disk array, nothing big… Once a day we make backup of our entire server park to one array.</font></span>
<br><span lang="fr"><font size="2" face="Arial">And I would use glusterFS to replicate my backup data to the second disk array.</font></span>

<p><span lang="fr"><font size="2" face="Arial">I have configured gluster for that but I have a very important question :</font></span>
<br><span lang="fr"><font size="2" face="Arial">Do GlusterFS support hard link on Linux system ?</font></span>
<br><span lang="fr"><font size="2" face="Arial">Of course we need many hard links to map data which don't change between two backups.</font></span></p></div></blockquote><div>Ofcourse yes.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

<p><span lang="fr"><font size="2" face="Arial">My second question is : Why the command<i> gluster volume start REP_TEST</i> automatically mount the volume in /etc/glusterd/mount/REP_TEST ??</font></span></p></div></blockquote>
<div><br></div><div>This should not happen automatically by default. The possible cases where you get mount points on servers are below:</div><div><br></div><div>* while using 'quota' feature: need one time initial mount, which crawls through the directories to update the current usage details. It should be unmounted automatically once the job is complete.</div>
<div>* when you are doing a 'rebalance': a mount point will be there during the time of 'rebalance' (as long as the rebalance is running), and should be on just the machine issuing the 'rebalance' and should be automatically unmounted.</div>
<div>* when you issue 'replace-brick' : to send some internal 'commands' we need a fuse mount, and hence will be doing a mount, which will get umounted automatically.</div><div>* while using 'geo-replication': 'path of the mount point here '/tmp/some-uniq-string', and it doesn't get visible on your mtab.</div>

<p><span lang="fr"><font size="2" face="Arial">This situation is very bad for me because I backup /etc changes all day long… and I don't want backups my entire storage array with /etc…</font></span></p>
<p><span lang="fr"><font size="2" face="Arial">I'm starting research for the second point… but if someone can give me the good conf file ? :)</font></span></p></div></blockquote><div><br></div><div>change the 'option working-directory /etc/glusterd/' to 'option working-directory /something/else' in glusterd.vol file (in $prefix/etc/glusterfs/glusterd.vol) </div>
<div><br></div><div>That should fix it.</div><div><br></div><div>Regards,</div><div>Amar</div><div><br></div></div>
