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. -----Original Message----- From: Fernando Frediani <fernando.frediani(a)upx.com.br&gt; Date: Wednesday 23 November 2016 at 16:31 To: Pavel Gashev <Pax(a)acronis.com&gt;, &quot;users(a)ovirt.org&quot; <users(a)ovirt.org&gt; Subject: Re: [ovirt-users] GFS2 and OCFS2 for Shared Storage 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 ?
