Hi Sam,

One option if you have it available is to patch your sources to version
16 fs version 4 that mm@ has made a patch for recently. This patch
contains the fix to the bug that causes this situation to happen during
a power outage or other unexpected quick failure.

The patches mentioned here may not help you recover but might just help
stop your data loss in the future if your pool can not be repaired. I am
unsure if anything in these patches will actually help resolve your
issue but it might be worth a shot. Martin is CC'd, maybe he has further
knowledge and notation he could add to this.

Two good references:

And Ill forward mm@ update emails directly to you following this email.


Ye Ole Patch fer v16: Ive been running this for over a week now.

Martin, Sam:
After patching I had to move a few files around in the source directory,
and create two directories. Namely *.py on recent 8.1-STABLE source.
Since these directories do not exist on the system it just leaves the
said files in the base of the source tree.

Created these directories: ( mkdir -p %%BELOW%% )
/usr/src/cddl/contrib/opensolaris/cmd/pyzfs
/usr/src/cddl/contrib/opensolaris/lib/pyzfs/common/

Moved these files:
mv /usr/src/pyzfs.py /usr/src/cddl/contrib/opensolaris/cmd/pyzfs/
mv /usr/src/*.py /usr/src/cddl/contrib/opensolaris/lib/pyzfs/common/


Good luck,
