@Neil sorry but I didn't get to reply to all on my last 2 emails, so
here is goes again so it's archived.
/dev/sdh3:
Magic : a92b4efc
Version : 1.0
Feature Map : 0x0
Array UUID : 828ed03d:0c28afda:4a636e88:7b29ec9f

Layout : far=2
Chunk Size : 256K
Device Role : Active device 0
Array State : AAAAAAAA ('A' == active, '.' == missing)
The only drive that didn't get affected is far=3. Any suggestions? I
have the drives on separate controllers and when I created the array I
set up the order as /dev/sda3 /dev/sde3 /dev/sdb3 /dev/sdf3 and so on.
so I would assume the same order would be used, also note that I ran
luksFormat on /dev/md1 then ran pvcreate /dev/md1 and so on. Will I have
issues with luksOpen after recreating the array? I removed the /dev/sdh1
drive so now the output is like:
