Hi, it seems that older zfs images (from zfs send) cannot be imported into recent illumos versions. These are dumps from a "pre-features" zpool. I get
ro suntc ~ # cat 32@20100825 | zfs receive -d rpool
cannot receive new filesystem stream: invalid backup stream
while I can still import those on an older illumos (in oi151.a8).
This is what zstreamdump sees:
# cat 32@20100825|zstreamdump
BEGIN record
hdrtype = 1
features = 0
magic = 2f5bacbac
creation_time = 4c751a60
type = 2
flags = 0x0
toguid = d5549c3062863864
fromguid = 0
toname = Processor/Results/imk/32@20100825
END checksum =
ac3419bb76a98f7/9a5ac336e407bdf3/c07a3f469bc7e40e/f03a369ef26634ee

Is this a bug or are "non-feature" dumps in general not importable
on "feature"-zpools ?
