Hi, The last sentence seems to mean that Gigi wants to create a GFS on top of a NFS FS. This GFS will be then exported thru NFS . Gigi, is that wjat you want to do ? PS: how is it going Rafael ? 2009/9/27 Rafael Micó Miranda <rmicmirregs@xxxxxxxxx>: > Hi Gigi, > > El vie, 25-09-2009 a las 19:09 -0500, Mathew, Gigi (JSC-EG)[Jacobs > Technology] escribió: >> Hi: >> >> >> >> I am configuring a Dell EqualLogic iSCSI array in a RHEL 5.3 platform >> with two GFS2 volumes with RedHat Cluster Suite using DRAC (primary) >> and APC (secondary) fencing devices.
