Correct, if you upgraded this pool, you would not be able to import
it back on your existing Solaris 10 system.
My advice would be to wait.

Ray,
Log removal integrated into build 125, so yes, if you upgraded to at
least OpenSolaris build 125 you could fix this problem. See the syntax
below on my b133 system.
In this particular case, importing the pool from b125 or later media
and attempting to remove the log device could not fix this problem
unless you also upgraded the pool version, because it is the pool
version that provides support for this operation.
I hope someone else has a better idea...
Thanks Cindy. I need to stay on Solaris 10 for the time being, so I'm
guessing I'd have to Live boot into an OpenSolaris build, fix my pool
then hope it re-imports into Solaris 10 (I would imagine it wouldn't
though). Might be a little too adventurous for my tastes right now...
:)
I'd really like to know if the ZFS changes from b125 will be merged
into Solaris 10 either pre-U9 or for U9...
I'm debating just waiting to fix this until then.
Ray
Thanks,
Cindy

Well, it doesn't seem like this is possible -- I was hoping there was
some "hacky" way to do it via zdb or something.
Sun support pointed me to a document[1] that leads me to believe this
might have worked on OpenSolaris. Anyone out there in Sun-land care to
comment?
To recap, I accidentally created two zeparate slog/zil devices in my
zpool instead of a mirror. I want to remove one of them.
I wonder if this will be possible in Solaris 10 U9? I'm considering
migrating all my data off and rebuilding the zpool, but might wait for
U9 if I can remove zil devices then.
Thanks,
Ray
