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

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
