Hello,
Some time ago I added a separate log device to my root pool (with the
"bootfs" unset hack) but now I can't remove it from my pool :
# uname -a
FreeBSD zozo.afpicl.lan 10.0-CURRENT FreeBSD 10.0-CURRENT #0 r241027:

status: The pool is formatted using a legacy on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on software that does not
support feature
flags.

I tried unsetting bootfs before removing the log device. Not better.
I tried importing my pool with a 9.1-RC1 liveCD, removing the log
device. The same thing happens.
I tried by physically detaching the log device from my computer. The
system can't mount root. With the 9.1-RC1 liveCD, I can import the
pool with "-m" but then I still can't remove the log device from the
pool.
Any idea on what I could do ?
Thanks
