            lustre upgrade<br>
            To: <a moz-do-not-send="true"
              href="mailto:lustre-discuss@lists.lustre.org">lustre-discuss@lists.lustre.org</a><br>
            <br>
            <br>
            Would it make sense to run<br>
            "tunefs.lustre --mgs --writeconf --mgs --mdt /dev/sda
            /dev/sdb" ?<br>
            <br>
            The original mkfs command used to create the MDT was<br>
            mkfs.lustre --reformat --fsname=iconfs --mgs --mdt
            --backfstype=zfs --device-size 131072 \<br>
            --index=0 lustre-mgs-mdt/mgsmdt0 mirror /dev/sda /dev/sdb<br>
            <br>
            Not sure if both device names should be included or the
            zpool name.<br>
            <br>
            The latest 2.5.x version also fails to mount MDT with
            similar messages, though<br>
            zpool seems intact... is there anyway to get MDT to mount?<br>
