I've been running 100->200TB OSTs making up small petabyte file systems for the last 4 or 5 years with no pain. Lustre 2.5.x through current generation.
Plenty of ZFS rebuilds when I ran across a set of bad disks that went fine.

Hi All We recently purchased new storage hardware, and that gives us the options of creating big zpools for OSTs (>100TB per OST), I am wondering if anyone has any experience of using big OSTs and if that would impact the performance of lustre in a good or bad way? Any comments or suggestions are appreciated! Cheers! ________________________________ -Wenjing [email protected]<mailto:[email protected]>
