Hi, 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
These are the ones (at least partly) we modified cluster.data-self-heal-algorithm diff cluster.background-self-heal-count 16 performance.io-thread-count 32 performance.high-prio-threads 24 performance.normal-prio-threads 24 performance.low-prio-threads 16 performance.least-prio-threads 4 Check #> gluster colume get VOLUMENAME all For more And even after optimization it will still take very long Regards Soeren From: Юрий Полторацкий <y.poltorats...@gmail.com<mailto:y.poltorats...@gmail.com>> Date: Monday 25 May 2015 12:46 To: "users@ovirt.org<mailto:users@ovirt.org>" <users@ovirt.org<mailto:users@ovirt.org>> Subject: [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.
