ZFS file recovery

Looking for the senior ZFS admin ready to dig deep to recover three big files.

Time is very, very limited!

Please ask should you have any questions!

Thank you!

After zpool export/import and upgrading OS I lost three Vbox files. their size now ~[url removed, login to view] instead of 50-100GB. All snapshots are size 0.

Zpool status - healthy. Two other Vbox VMs work absolutely no problem. Looks like everything is in place but I keep them off for now.

Export/import went smooth.

Need to recover those files somehow. They there still there before the upgrading...

Tried to follow the following with no luck:

[url removed, login to view]

More details:

I have three VirtualBox VMs. They all have two or three HDDs attached.

And all HDDs reside in the their own zfs systems.


Domain controller VM.

Disk C - /tank/vm/dc/system/[url removed, login to view]

Disk E - /tank/vm/dc/exchange/[url removed, login to view]

Disk F - /tank/vm/dc/exchange/[url removed, login to view]

I'm doing separate snapshots of those ZFS systems.

Normal size of the [url removed, login to view] is about 60-70GB, don't remember exactly. Now its size only [url removed, login to view] and I can't

even attach it the VM.

Same story for the data.vdi.

[url removed, login to view] is actually 15GB instead of 55GB. I was able to start a server but that's about it....

Other two VMs have similar structure but size looks fine and I was able to recreate a VMs and start and stop


It's a DC that screwed... All my snapshots are 0 in size for the /tank/vm/dc/exchange /tank/vm/dc/data. I'm

keeping only a couple months of snapshots.

DC was running just fine Saturday morning.

The original system was opensolaris 134b. I've replaced with fresh openindiana. and after with Ubuntu 12.04 with

ZFS. Openiniana was throwing an error message (assertion) when I've tried zdb. that's why I switched to Ubuntu.
