[zfs-discuss] Resilver endlessly restarting at completion

2010-09-27 Thread Tuomas Leikola

134 it is. This is an OpenSolaris rig that's going to be replaced within the next 60 days, so just need to get it to something that won't through false checksum errors like the 120-123 builds do and has decent rebuild times. Future boxes will be NexentaStor. Thank you guys. :) -J On Sun, Sep
