for</font><br><font size=2 face="sans-serif">finding detailed steps on setting up
a cluster or creating a file system. Or open a PMR and work with IBM support
to set it up.</font><br><br><font size=2 face="sans-serif">In your case (just as an example) you
can use the below simple steps to delete and recreate the file system:</font><br><font size=2 face="sans-serif">1) To delete file system and NSDs:</font><br><font size=2 face="sans-serif"> a) Unmount file system - mmumount
<fs> -a</font><br><font size=2 face="sans-serif"> b) Delete file system -
mmdelfs <fs></font><br><font size=2 face="sans-serif"> c) Delete NSDs - mmdelnsd

in one system pool and having dataAndMetadata and data and metadata replica
and directly attached to the nodes, you can use following steps:</font><br><font size=2 face="sans-serif"> a) Create a /tmp/nsd file and
fill it up with below information</font><br><font size=2 face="sans-serif"> <Disk name>:::dataAndMetadata:1:nynsd1:system</font><br><font size=2 face="sans-serif"> <Disk name>:::dataAndMetadata:2:nynsd2:system</font><br><font size=2 face="sans-serif"> b) Use mmcrnsd -F /tmp/nsd to
create NSDs</font><br><font size=2 face="sans-serif"> c) Create file system using (just
an example with assumptions on config) - mmcrfs /dev/fs_gpfs01 -F /tmp/nsd
-A yes -B 256K -n 32 -m 2 -r 2 -T /fs_gpfs01</font><br><br><font size=2 face="sans-serif">You can refer to above guide for configuring
it in other ways as you want. If you have any issues with these steps you
can raise PMR and follow proper channel to setup file system as well.</font><br><br><font size=2 face="sans-serif">Regards, The Spectrum Scale (GPFS) team<br><br>------------------------------------------------------------------------------------------------------------------<br>If you feel that your question can benefit other users of Spectrum
