False alarm. My apologies.
There was a stale superblock on the disk I was trying to hot add as a spare. Once I wiped the superblock it was successfully added to the array.
That being said, the error message issued wasn't exactly appropriate.
Regards,
Sean

Subject: Hot add not supported by version 1.x superblocks?
Hello Neil.
I have a RAID1 built using v1.2 superblocks. I seem to not be able to hot add a spare drive to this array.
I get the error message:
"HOT_ADD may only be used with version-0 superblocks"
Does this really mean that hot add is not supported for arrays built with v1.x superblocks?
If so this seems like a big regression in functionality. In this case, are there technical reasons why v1.x cannot support hot add?
I am using a stock 2.6.18 kernel with mdadm v2.5.4
Thanks,
Sean
