How to setup locklun on server running multipath?
We have moved all the LUN's the cluster use to a SAN that supports multipath.. so it's now totaly 48 sda, sdaa and so on..
earlier I had 6 devices in /dev sda-sdf
each device was a lun and the lock lun was sdb1
When we moved to the new SAN all the LUN's got 8 devices each..
I have tryed to set the lock lun to /dev/dm-2 or /dev/mpath/mpath2 which is the lun we want to use but when I check t he conf I got an error that says this:
Error: /dev/dm-2 is not a valid device. Validation failed.
Error: Invalid data for cluster lock LUN configuration
cmcheckconf : Unable to verify cluster file: /usr/local/cmcluster/conf/cluster1.ascii
