I would like to add an internal bitmap to my RAID1 array. It uses v 0.90 superblocks. Reading the man page, I believe I do this with: "mdadm --grow --bitmap=internal /dev/mdX" correct? How do I know how much space is available on the superblock when mdadm will perform it's computation "to make best use of available space"? I'm curious because perhaps I should change to 1.x superblocks in the future (for non-bootable arrays).
