OK - this appeared to work: imported the zpool into opensolaris 77, did a zpool scrub - and no kernel panics. Cool! But - after reimporting the zpool back into Solaris10u4 (where it belongs) a zpool scrub still causes a kernel panic - although it seemed to take a bit longer to panic. Same error message as before - panic[cpu1]/thread=2a1015c7cc0: Dec 15 12:49:35 server unix: [ID 361072 kern.notice] zfs: freeing free segment (offset=423713792 size=1024) Note that opensolaris 77 and Solaris10u4 are on the same physical hardware - I'm just booting off different system disks. >> I pulled your crash dump inside Sun, thankyou, but I haven't >> had a chance to analyze it so I've passed the details on to >> more knowledgeable ZFS ppl. >> >> >> James C.
