How to remove a drive from a 2-drive RAID 5 array?
- by DrSAR
There is some information available on shape changes in RAID arrays but I'm a little nervous and would like confirmation:
Problem: I have 2 500GB drive as software raid 5 (mdadm). I would like to free one of the two drives since RAID-redundancy is for wimps... Can I just
mdadm --grow --array-size=1
followed by a
mdadm --grow --raid-disks 1?
This seems too simple. How would I specify which drive gets freed? Part of the reason for this maneuver is that I don't have additional space to run a backup.
