I'm still struggling with slow resilvering performance. There doesn't seem to be any clear bottleneck at this point.. and it's going glacially slow. scrub: resilver in progress for 11h2m, 27.86% done, 28h35m to go Load averages are like 0.13-0.15 range, CPU usage is <10%, the machine is doing n

i might be wrong because i'm kind of new but i THINK you need to disable automatic snapshots when resilvering, at least on the older version you did. if not it would restart every time a new snapshot was madebut then again, i may be wrong. On Fri, Jul 10, 2009 at 6:18 PM, Galen wrote: > I
