I seem to be having exactly the problems you are describing (see my postings with the subject 'zfs on a raid box'). So I would very much like to give b77 a try. I'm currently running b76, as that's the latest sxce that's available. Are the sources to anything beyond b76 already available? Would I need to build it, or bfu? I'm seeing zfs not making use of available hot-spares when I pull a disk, long and indeed painful SCSI retries and very poor write performance on a degraded zpool - I hope to be able to test if b77 fares any better with this.
