Are you sure Pavel ? As far as I know and it has been discussed in this list before, the limitation is in CLVM which doesn't support Thinprovisioning yet. LVM2 does, but it is not in Clustered mode. I tried to use GFS2 in the past for other non-virtualization related stuff and didn't have much success either. What about OCFS2 ? Has anyone ? Fernando On 23/11/2016 11:26, Pavel Gashev wrote:
Fernando,
oVirt supports thin provisioning for shared block storages (DAS or iSCSI). It works using QCOW2 disk images directly on LVM volumes. oVirt extends volumes when QCOW2 is growing.
I tried GFS2. It's slow, and blocks other hosts on a host failure.

Has anyone managed to use GFS2 or OCFS2 for Shared Block Storage between hosts ? How scalable was it and which of the two work better ?
Using traditional CLVM is far from good starting because of the lack of Thinprovision so I'm willing to consider either of the Filesystems.
Thanks
