Why is your raid metadata using this old version? mdadm-3.2.2-6.fc15 will not create this version of raid array by default. There is a reason we have updated to a new superblock.

As you may have seen, the array was created in 2006, and has gone through
several similar grow procedures.

Does this problem still occur if you use a newer superblock format (one of the version 1.x versions)?

I suppose not. But that would destroy the "evidence" of a possible bug.
For me, it's too late, but finding it could help others to prevent this situation.
If there's anything I could do to help find it, now is the time.

If the people on this list know enough, I will proceed.

Thanks,
Pim
