zfs discuss - Jun 2008 - Util to remove (s)log from remaining vdevs?

After having to reset my i-ram card, I can no longer import my raidz pool on
2008.05.

Also trying to import the pool using the zpool.cache causes a kernel panic on
2008.05 and B89 (I''m waiting to try B90 when released).

So I have 2 options:
* Wait for a release that can import after log failure... (no time frame ATM)
* Use a util that removes the log vdev info from the remaining vdevs.

Would such a util be the easiest/fastest way to get going?  If so, I''d
be willing to pay up to $500 for a solution in the next 2 weeks.  I know
that''s not much, but I''m just a home user.

Any other recommendations on getting this going would be appreciated.

(Yes the super critical stuff was backed up elsewhere, but this was the
backup/storage for everything else...)

I''m not sure why the URL didn''t show correctly in the previous

If this URL still doesn''t list show properly, you can track the thread
down by searching the forum with a search for   log    and a user name of

This link worked for me:

Thanks for the info, and that did have some good tips!

I think I might try hacking the label on the log device first.  I''ll
post if I get something working.

If that works, it might be best to make a bit for bit copy of the log device and
gzip it.  It should be small assuming you are using a ram based device (and have
zeroed it before making the label).

Now I just need some time to start digging into the on disk format...
