Ok... I don't feel quite as silly... as I had roasted one of my test machines (unable to mount /) - I had to do a full rebuild from scratch. Well... It seems I had 2 of 3. For anyone who ever needs to disable their Qlogic fiber card from auto-starting in the future - do all of the following 3

DOH... ok I feel stupid... :-) Well 'blacklist scsi_transport_fc' didn't work... but - 'blacklist qla2xxx' works fine. Amazing how all the docs I found said to use - remove qla2xxx modprobe -r - kind of stuff... and all that I really had to do was add the silly thing to the blacklist... :-)

Kaloyan, I agree - disabling the qla2xxx driver (Qlogic HBA) from starting at boot would be the simple method of handling the issue. Then I just put all the commands to load the driver, multipath, mdadm, etc... inside cluster scripts. Amusingly it seems I am missing something very basic - a

Hello Kaloyan, Thank you for the thoughts. You are correct when I said - "Active / Passive" - I simply meant that I had no need for "Active / Active" - and floating IP on the NFS share would be exactly what I had in mind. The software raid - of any type, raid1,5,6 etc... is the issue. From
