I'm sure others can provide a much more in depth answer but in short...
Not all "file systems" are cluster aware.
Something like GFS can be active on all nodes at the same time; because
it uses a lock manager that makes every node in your cluster "chat" with
each other to determine who is writ
tag so the
lv will be active on one system
RH-Cluster supports floating LVs on its own, just add the LV + FS as
resource.
If you're not using a LUN for mirror-logging, your're moving the LVs from
one system to the other at the cost of one full rebuild of the host based
mirror.

1. Modify /etc/modprobe.conf - and comment out the line "#alias
scsi_hostadapter2 qla2xxx"
2. Rebuild the init - I use this - "mkinitrd -f /boot/initrd-$(uname
-r).img $(uname -r)"
3. Add "blacklist qla2xxx" - to /etc/modprobe.d/blacklist

Hail Linux Cluster gurus,
I have researched myself into a corner and am looking for advice. I've
never been a "clustered storage guy", so I apologize for the potentially
naive set of questions. ( I am savvy on most other aspects of networks,
hardware, OS's etc... but not storage systems).
