[zfs-discuss] zfs: allocating allocated segment(offset=77984887808 size=66560)
how does one free segment(offset=77984887808 size=66560)
on a pool that won''t import?
looks like I found

when I luupgrade a ufs partition with a
dvd-b62 that was bfu to b68 with a dvd of b74
it booted fine and I was doing the same thing
that I had done on another machine (/usr can
live on raidz if boot is ufs) on a
zfs destroy -r z/snv_68 with lzjb and {usr var opt} partitions
it crashed with:
