Yes, a full disclosure will be made once it's back to normal (hopefully that event will happen).
The pool is mounted RO right now, and I can give some better stats; I had 10.3 TB of data in that pool, all a mix of dedup and compression. Interesting enough, anything that wasn't being touched (i.e. any VM that wasn't mounted, or file that was being written to) is perfectly fine so far - So that would mean over 95% of that 10.2 TB should be clean. I've only copied 10% of it so far, but it's all moved without issue. The files that were in motion are showing great destruction - I/O errors when any attempt is being made to read them. At this stage, I'm hoping that going backwards in time further with the txg's will give me solid files that I can work with. George has some ideas there, and hopefully will have something to try around the time I'm finished copying the data. This should stand as a warning that even a ZFS pool can disappear if it takes corruption in the right area. Hopefully there will be time and enough evidence for a "how did this happen" type of look.. I'm starting to beef up my second SAN device more as I wait for my primary pool to recover. I wanted to stress-test this SAN design, I guess I have covered all the bases - right up to pool destruction and eventual partial recovery. Once this is all production, I have to keep enough business processes running regardless if one of the pools goes down. Many thanks to George and his continued efforts.

Rgds, Mark. 2011/2/8 Chris Forgeron <cforge...@acsi.ca<mailto:cforge...@acsi.ca>> Quick update; George has been very helpful, and there is progress with my zpool. I've got partial read ability at this point, and some data is being copied off. It was _way_ beyond my skillset to do anything. Once we have things resolved to a better level, I'll post more details (with a lot of help from George I'd say). _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org<mailto:zfs-discuss@opensolaris.org> http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
