Hi!
I have a four-disk Raid-10 array that I created and mount with
mdadm. It seems like every re-boot, either the array is not
recognized altogether, or one of the disks is not added. Manually
adding using mdadm works.
What superblock version and partition type did you use? mdadm -D please.
Thanks for the reply. I've been wondering why no one answered me - then
discovered your answer in my mailbox! Must have been hiding somewhere .

Anyway -
