hi,
i'd like to know the current state of the raid6 driver. we are now
switching one of our server from 8 x 200GB to 8 x 300GB(or 400GB).
so which is the better if we use:
- 7 x 300GB in raid5 and one 300GB spare or
- 8 x 300GB in raid6?
it seems the same to me since both case we can get two disk faild and
the same capacity. so why we choose raid6 over raid5 (when raid5 seems
to be more stable then raid6)?
another question is there any upper limit for one raid5(6) partition?
i read 1TB and 2TB too (although we already have a raid5 which is
larger then 1TB). these are still real limit? or what is the current
limit?
thank you for your help in advance.
yours.
With RAID5 and a spare, if another, rarely or never used area is found
to be bad on rebuild, your spare is of no use, and without heroic
measures, all is lost. RAID6 can handle that scenario.
