[ovirt-users] glusterfs takes a long time to syncing after host has been rebooted

Hi. 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. I've googled for this issue without success. Is it normal situation? Or what can I do to resolve the problem? I can provide any additional info. Thanks.
