I have 1 data disk that went disabled ( I copied the contents), I'm now pre-clearing (at approx 20% done) a fresh disk to replace it.  Not a problem, I've done this before.

However, one of my 2 parity disks went disabled with read errors (?)  I know the procedure to rebuild a disk onto itself, my question is

whats the best and safest strategy here?  Should I deal with rebuilding on to itself the disabled parity disk first?  and than deal with the pre-cleared data disk?  I'm thinking so, because  1. I have a copy of the contents from the data disk.  and 2. if the other parity disk get stupid on me I may have a bigger problem to deal with.

 

Any thoughts would be appreciated.

 

Thanks in advance..

It is really up to you I think.   

 

You can do both in parallel if you want, and I see no reason why this should be much riskier that doing them one at a time and avoids the need to do two rebuild cycles.  If you do want to do just one initially going for fixing the second parity seems best.

Thank you Sir..
