Re: [ovirt-users] gluster replica volumes with different data usage

I am referring to the other 2 volumes which are replicas and should have the exact same data. Checking the status of other bricks in ovirt (bricks used from iso and export domain) I see that they all report same usage of data on the data volumes, except the "vms" volume used for storing vms. Ah, okay. Some of the things that can cause a variation in disk usage: - Pending self-heals in gluster (check if `gluster volume heal <volname> info` doesn't show any entries. Also if there is anything under `.glusterfs/landfill` folder of the bricks). - XFS speculative preallocation - Possibly some bug in self-healing of sparse files by gluster (although we fixed known bugs a long time back in this area).
