Multiple disks groups
-
Hello,
we have nodes with multiple disk group.
Does someone experienced multiple xostor on different local group ?
In our case
- 2x1TB & 2x2TB
It should works easily because we gonna register 2 xostor, but maybe should we put all disks in the same VG ? but in this case, the max vdi size will be lower ?
I purpose to edit the install script to provide group name selection to permit this use case easily.
It's ok ?

Hello,
From my test, the result is having multiple xostor is not possible at this time. it's blocked.
( i didn't save the precise error message, but the error was clear: cannot have more than one XOSTOR in the pool ).

@henri9813 XOSTOR is "vSAN".
You ideally would want to consume all of your disks across all of your hosts to create an as large and as performant VG as possible. Splitting your disks into different VG's not only would decrease your performance, but is also likely hugely complex and outside of the original design scope for XOSTOR.

hello @DustinB.
Yes you right, i would perform this to be able to have VDI with more than 1TB disk. ( which will not be possible because my smallest disk is 1TB (so, 879GB )...

Is that actually a limiting factor? It makes sense, but I've never used XOSTOR so I'm not completely sure what the limitations are.
My assumption would be you'd have the same 2TB limit, but again, I honestly don't know.

Hello, @DustinB
The https://vates.tech/xostor/ says:
The maximum size of any single Virtual Disk Image (VDI) will always be limited by the smallest disk in your cluster.
But in this case, maybe it can be stored in the "2TB disks" ? Maybe others can answer, i didn't test it.
