RE: [Linux-cluster] create GFS file system on imported iSCSI disk



/etc/fstab will require the _netdev flag or else the filesystem will not
get mounted during boot.

There aren't any special steps needed for iSCSI over any other kind of
shared storage (once you've configured the initiators & the devices are
visible to the OS).

Creating volume groups and using logical volumes for GFS is a good idea
if you are likely to want to resize your devices at a later time but is
not strictly necessary.

Other than that, the steps you detailed should work fine.

Kind regards,
Bryn.
