Re: Converting RAID5 to RAID6 and other shape changing in md/raid

18 May 2010, 02:01 UTC

I'm in a position where I have a 6 drive (1 failed, 5 active and working with the array in a degraded state) RAID6 array that I'd like to shrink/grow to a 5 drive RAID5 array.

The logic is that I've had a bad run with 1.5tb sized drives, so I'm more itnerested in just making do with the 5 drives / 6tb worth of useable storage I have now - and limp along until I can put together a new array from 2tb drives to take it's place. It also doesn't help that my current array is reiserfs, and I'd really feel a lot more comfortable with ext or xfs.

So I admit I'm having problems with the directions so far, insofar as shrink/growing the array from 6x RAID6 to 5x RAID5.

Suggestions or assistance?
