We just got a new system to use as a zfs file server with 8 drives on 2
controllers. I''ve installed on and mirrored c4t0d0s0 and c5t0d0s0, and
am now trying to create a mirrored set out of the rest of the disks, however all
of them are giving me i/o errors, e.g.:
# uname -a
SunOS zfs01.server.peak.org 5.11 snv_86 i86pc i386 i86pc
# format
