Thanks for your insights, I'm also relatively new to solaris but i've been on linux for years. I've just read more into the logs and its giving these errors for all 3 of my disks (sd0,1,2). I'm running a raidz1, unfortunately without any spares and I'm not too keen on removing the parity from my pool as I've got a lot of important files stored there. I would agree that this seems to be a recoverable error and nothing is getting corrupted thanks to ZFS. The thing I'm worried about is if the entire batch is failing slowly and will all die at the same time. Hopefully some ZFS/hardware guru can comment on this before the world ends for me :P Thanks Matt No virus found in this outgoing message.
