twitami Posted September 18, 2006 Share Posted September 18, 2006 So I have seen some posts about te Parity drive "shrinking" when using all the same size drives. Would using a larger drive for the firat slot be a good idea, or is this not a problem anymore? Quote Link to comment
teamhood Posted September 18, 2006 Share Posted September 18, 2006 A few people have reported this problem as you are aware. I started my array off with a 400 GB parity and then 2 300GB drives. I have since added 3 more 400GB drives with zero problem in regard to the parity size problem. My huge thread had a few things go wrong, but none of it is related to the unRAID OS, but all to do with hardware issues Quote Link to comment
Joe L. Posted September 18, 2006 Share Posted September 18, 2006 So I have seen some posts about te Parity drive "shrinking" when using all the same size drives. Would using a larger drive for the firat slot be a good idea, or is this not a problem anymore? My initial array was a pair of identical 500Gig drives. I did not run into the issue you are describing. I've only read of it happening to two people. I think Tom was recently working with one of them to try to isolate the cause. Who knows, it might be a subtle bug that only happens when the routine that initially calculates disk size "rounds" the number of bytes/cylinders/tracks/blocks (whatever Tom is comparing) differently than the one that later checks it when you add a subsequent drive.

limetech Posted September 18, 2006 Share Posted September 18, 2006 Regarding parity drive size: the Parity drive does need to be the same size or larger than all the other drives. Regarding the case of the mysterioius shrinking Parity drive: Yes it's quite mysterious. So far we haven't been able to reproduce this. Quote Link to comment
