I have a 5 disk version 1.0 superblock RAID5 which had an internal
bitmap that has been reported to have a size of 299 pages in /proc/
mdstat. For whatever reason I removed this bitmap (mdadm --grow --
bitmap=none) and recreated it afterwards (mdadm --grow --
bitmap=internal). Now it has a reported size of 10 pages.
Do I have a problem?
