Just an update for everyone on this (and for the archives), Did some digging, and had a look at the device mapper config
# dmsetup -C info Name Maj Min Stat Open Targ Event UUID mpath0 253 0 L--w 1 1 0 VolGroup00-LogVol01 253 3 L--w 1 1 0 LVM-2sahQifzg9s9k0xSkpnzpGCYd7JNVXzUof6XmQ0fhzJ6jIbQLciAbm6lJLwK0Aex VolGroup00-LogVol00 253 2 L--w 1 1 0 LVM-2sahQifzg9s9k0xSkpnzpGCYd7JNVXzUt3sJ3nwvJF8cr6ebv5AdnY0j4Ajl6U0I mpath0p1 253 1 L--w 0 1 0 Those 2 multipath devices shouldn't have been there, and indeed mpath0p1 were my 2 recalcitrant disks. # dmsetup -C remove mpath0p1 # dmsetup -C remove mpath0 And they were both gone (you need to start at the bottom of the tree when removing them). A quick fdisk of my disks to create sdb1 and sdc1 partitions, and my array will be synched in 204 mins...:) Thanks to everyones help for pointing me in the right direction.. It was a trip I would have preferred not to have made, but like all trips like that, it's been illuminating. Thanks again.
