Re: [ovirt-users] ovirt - unsupported GFS config ??
- Yes, database will run in VM , but with RMAN online backups. So VM takes over 1,4TB . This VM wil run 5-6x :o( - I have no special issues with 512MB shard size, looks OK but not tested for such databases yet ( Waiting for 3.7.10 gluster (dupl.healing fix)) regs.

Stripe is not supported. What you need to do instead is turn on sharding for the volume.
