I am running 2.6.9-22.ELsmp kernel with device-mapper-multipath-0.4.5-6.0.RHEL4. I have multipath
configure and working. My HBA's are Emulex LP11000.

I can create an ext3 filesystem on /dev/dm-1 and mount it. But if I reboot the node and try mounting
the filesystem I get the following error:
[root@io1 device-mapper-multipath-0.4.5]# mount -t ext3 /dev/dm-1 /nfswork/
mount: wrong fs type, bad option, bad superblock on /dev/dm-1,
or too many mounted file systems
