<div>Hi,</div>
<div><br>
</div>
<div>This is strictly speaking a gluster issue, not an ovirt issue, however, first of all, it does take very long to resync, that is normal, second, we have vey good experiences so far in tuning a few of the parameters in gluster</div>
<div><br>
</div>
<div>These are the ones (at least partly) we modified</div>

</div>
<div><br>
</div>
<div>Check </div>
<div><br>
</div>
<div>#> gluster colume get VOLUMENAME all</div>
<div><br>
</div>
<div>For more</div>
<div><br>
</div>
<div>And even after optimization it will still take very long</div>
<div><br>
</div>

<div dir="ltr">Hi.<br>
<div><br>
I am testing oVirt 3.5.2 with 3 hosts (Dell R210). Storage type is GlusterFS (replicate 3): each host has a single 3TB HDD. When I put one host into maintence mode, then reboot it and after system has been started, the glusterfsd proccess takes a long time
(more then hours with gigabyte network) to syncing. It seems to be reload all data instead of download only changes . I have several VMs, but only one VM was running (postfix relay) at that moment, so there were no lots of changes on gluster volume.
<br>
<br>
I've googled for this issue without success. <br>
<br>
Is it normal situation? Or what can I do to resolve the problem? I can provide any additional info.<br>
<br>
Thanks.<br>
