The lvm partition was missing and so far I haven't been able restore the file system. All data is missing??</div><div>I don't understand the situation and I don't know if it's due a xfs filesystem or glusterfs fail. Someone it has been this situation?</div><div><br></div><div>Thanks.</div><div><br></div><div><br></div></div>
