After zpool export/import and upgrading OS I lost three Vbox files. their size now ~1.5MB instead of 50-100GB. All snapshots are size 0. My secondary server - same picture.
And that's a DC with Exchange and user files.

Export/import went smooth. Same server, just an OS upgrade.
Zpool status - healthy. Two other Vbox VMs work absolutely no problem. Looks like everything is in place but I keep them off for now.
Need to recover those files somehow. They there still there before the upgrading...

Tried to follow the following:

it's been almost 24 hours...

Any ideas?

Thanks!

My first impression is that it is impossible. (and if it isn't, it would be nice to know how)

Were the VMs shutdown during this process? Are you doing anything funny with your ZIL?

What does it mean that the snapshots are 0? If your dataset is /tank/vm, you should be able to
cd /tank/vm/.zfs/snapshots
ls -l
cd snapshot_you_see
ls -l

and you should see the earlier version of your files.
