[ovirt-users] Gluster deployment - Arbiter volume - different disk size - volumes sizes

Hello, I have one more question for the gluster deployment. I have three servers with different disk sizes : - server1 : 3 x SSD configured in raid 5 mode for a total capacity of 900 GB - server2 : 6 x SSD configurerd in raid 6 mode for a total capacity of 2,2 TB - server3 : same as server2 (2,2TB) Because my server1 has less capacity than the others I will use it as an arbiter volume (during the deployment I will declare it as the last host : host3). Is-it correct ? So I will create 4 volumes : - engine : 50 GB type replicated without arbiter - data : ?? - vmstore : ??? - iso : 15 GB replicated with arbiter volume Can someone tell me what are the differences between data and vmstore volume ? In the earlier version there was only information about data volume and export volume. I found nothing about vmstore volume. If the wmstore is, as its name suggests, the place where all vm files will be stored including vm disks images, I think I have to set most of the capacity for this volume. So at the end my 4 volumes will be : - engine : 50 GB type replicated without arbiter - data : 500 TB replicated with arbiter volume - vmstore : 1,5 TB replicated with arbiter volume - iso : 15 GB replicated with arbiter volume What do you think of this ? Thanks, Florent
