Re: [ovirt-users] GFS2 and OCFS2 for Shared Storage
Fernando,
Clustered LVM doesn’t support lvmthin(7)
http://man7.org/linux/man-pages/man7/lvmthin.7.html
There is an oVirt LVM-based thin provisioning implementation.

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,
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
Fernando
