An external bitmap means that if the link goes down, it keeps track of
which blocks are in sync and which aren't, and when the link comes
back up you re-add the missing device and the rebuild continues where
it left off.
mdadm --build /dev/md22 --level=1 --bitmap=/root/mybitmap \
--write-behind --raid-disks=2 /dev/localdevice --write-mostly /dev/remotedevice
One more question - is there a way to estimate the size of the bitmap
file? Does it depend on the size of the array?
What bitmap file size can I expect for a 600 GB array?
