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
You don't really need a data and vmstore. Vmstore I believe iaeamt to be the new iso domain but even it is not needed as all data domains act the same. You can use a seperate data and vmstore domain because it will give you greater flexibility in terms of backing up thr volumes so you can choose to backup just the vm data and not images On Wed, Sep 12, 2018, 5:30 AM florentl, <florentl.info@laposte.net> wrote:

For the engine, you will need at least 58 GB. I always use 62 just to be on the safe side. If you use 50, your install will fail. You don't need an ISO domain. ISO files can be stored in "data" or "vmstore". Each vm you create should have 2 disks, 1 for the o/s & 1 for the data. The o/s disk goes in "vmstore", the data disk goes in "data".
I just use engine and data in mine On Wed, Sep 12, 2018, 1:33 AM femi adegoke <ovirt@fateknollogee.com> wrote:
