ok i've been lurking here for a while studying "the whole cluster
thing", and i've made this progress:
two ILO2-based HP servers running CentOS 5.5 with fibre connections to a
one promise fibre array-based raid1 drive of 4TB (4x 2TB drives); and
Cluster Storage and Clustering packages installed.
using luci running on srv0 i've defined the cluster, added two nodes,
their fencing (IPMI Lan), and everything looks good.
on srv0 i changed the "wrk" raid1 storage to "Clustered: True", and sure
enough it shows up on srv1 as "Clustered: True". so i assUme i've done
everything right thus far...
since i'm aiming for a primary:primary cluster (HA), i should change
that cluster.conf parm for that, yes?
if i want to be able to access this "wrk" drive from a non-clustered
server via NFS, what's next?
q: the "wrk" array uses xfs (setup before the cluster). it's ok if it
gets levelled. do i need to use GFS2 or ZFS or some other
filesystem format, or can i continue to use xfs?
q: i'm assUming that i need to make NFS a managed service if i want it
to be HA, yes?
q: anything i've missed?
i'm amazed that this has been this easy thus far - kudos to all of you!
