There is a nasty bug in md in 2.6.18 affecting at least raid1.
This fixes it (and has already been sent to [email protected]).
### Comments for Changeset
This fixes a bug introduced in 2.6.18.
If a drive is added to a raid1 using older tools (mdadm-1.x or
raidtools) then it will be included in the array without any resync
happening.
It has been submitted for 2.6.18.1.
