Is that an implication that had all your data been on UFS (or ext2:) this time
around you would have got it all back? (I've got that impression through this
thread from things you've written.) That sort of makes it sound like UFS is
bulletproof to me.
Its definitely not (and far from it) bullet proof - however when the data on
disk is not corrupt I have managed to recover it - even if it has been a
nightmare - no structure - all files in lost+found etc... or even resorting to
r-studio in the even of lost raid information etc..
Yes but you seem to have done this with ZFS too, just not in this particularly
bad case.
There is no r-studio for zfs or I would have turned to it as soon as this issue
hit.
So as an update, this Company: http://www.klennet.com/ produce a ZFS
recovery tool: https://www.klennet.com/zfs-recovery/default.aspx and
following several code changes due to my case being an 'edge case' the
entire volume (including the zvol - which I previously recovered as it
wasn't suffering from the metadata corruption) and all 34 million files
is being recovered intact with the entire directory structure. Its only
drawback is it's a windows only tool, so I built 'windows on a stick'
and it's running from that. The only thing I had to do was physically
pull the 'spare' out as the spare already had data on it from being
previously swapped in and it confused the hell out of the algorithm that
detects the drive order.

Michelle
