I would like to be able to change a file system name. Towards that end, I
have run the following commands as an experiment:<br>
<br>
mkfs.lustre --reformat --fsname BEFORE --device-size=10000 --mgs
--mdt --mgsnode=10.2.9.1@o2ib0 /dev/mapper/map0<br>
dmesg -c<br>
mount -t lustre /dev/mapper/map0 /mnt/mdt<br>
dmesg -c<br>
umount /mnt/mdt<br>
dmesg -c<br>
tunefs.lustre --writeconf --fsname=AFTER --mgs --mdt /dev/mapper/map0<br>
dmesg -c<br>
mount -t lustre /dev/mapper/map0 /mnt/mdt<br>
dmesg -c<br>

Unfortunately, this does not work. Can someone please explain the correct
sequence of commands to ues? The output of each command is as follows.<br>
