Hi all, I have been presented a pair of servers (RHEL 5.2) connected to a dual port scsi array. The storage has been configured as one large disk partitioned into /dev/sdb1 /dev/sdb2,and /dev/sdb3 with dev/sdb3 the sole device in a physical volume. Several logical volumes have been created on the physical volume. Currently the logical volumes are mounted on server A. Server B was added to the mix as a new server. Server B sees the external storage with fdisk -l and the volumes with pvdisplay. My questions are, can an existing logical volume be used as a cluster resource that is mounted on one node or the other (but not both)? Would this work with just the existing LVM or would CLVM be needed? If I need CLVM, can the existing logical volumes be used without destroying the existing data? In either case, would all the logical volumes need to be mounted on the same server or can just one logical volume be mounted on one server while the remaining logical volumes are mounted on the other? The idea is to create an active-passive HA cluster of an existing web server. Any thoughts, ideas, comments, questions would be appreciated.
