Help! > Have you tried setting vfs.zfs.nopwrite_enabled=0 in /boot/loader.conf? Didn't even know about it. I looked at the Illumos commit log and figured out that I should be able to work around it by setting checksum=fletcher4. Since it's a production server I can't really take a reboot just to try this out. (I added it to loader.conf just now, so if I need to reboot it again before this bug is fixed, I can put it back to sha256.) -GAWollman
