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. -----Original Message----- From: <users-bounces@ovirt.org> on behalf of Fernando Frediani <fernando.frediani@upx.com.br> Date: Wednesday 23 November 2016 at 15:03 To: "users@ovirt.org" <users@ovirt.org> Subject: [ovirt-users] GFS2 and OCFS2 for Shared Storage 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.
