Subject Re: KVM + CLVM and Snapshots
Date Tue, 04 Apr 2017 10:13:14 GMT
Hi Florian,

I’ve spent quite a bit of time getting CLVM to work with KVM (in this case on CentOS6+7)
– and my experience is it’s not fit for purpose, suffering a lot of stability issues.
I do know there are others in the community who may have got this to work in the past, so
interested to hear other people’s experiences.

Wrt ScaleIO – not played with so can’t comment.

    as the cloudstack documentation explains CLVM is not supported with Cloudstack:
    "The use of the Cluster Logical Volume Manager (CLVM) for KVM is not officially supported
with CloudStack."
    We would like to change our hypervisor from Xenserver to KVM but we have no idea how to
use ScaleIO with KVM without using CLVM?
    The question is - why isn't CLVM supported? Is it because of snapshots are not allowed
on clustered VGs?
    Any idea how to use ScaleIO with KVM as shared storage?
    All the best,
