Ok gurus,
I got a little too crazy with my pool, and I'd like to learn a little more about recovery.
Basically I was playing with adding and removing slogs. The last iteration I was testing was using a ram drive. I know a little kooky, but not that uncommon among some of the zfs wizards in other places.
Obviously my device is not persistent, but I never had trouble remounting a pool missing a slog until now. I've tried the more aggressive import commands, but with no change. I'll do some more research, but I'm sure I'm not the only one that would benefit by the recovery procedures. Successful or not.
The box was rebooted gracefully. All drives are intact, and there is no corruption or missing data on the mirrored pairs. The slog is the device missing. I did try and import on a clean/reset freeNas as well. Haven't tried a live bsd cd or anything. This is a test pool, so no big deal.
I appreciate any wisdom given, hopefully it benefits many. Here is the result of my last attempt which shows the structure and error:
No rush or pressure. I'll fight it for a while as a recovery exercise. :)
