Hi.

I use freenas 9.3 in production mode. Every 1 hour workdays freenas take shapshots. No any problems was before today. i open files on my server and see no data after 20/03/15 11:30 AM. It is lost. Friday workday was fibished 5:30 PM and was not any problems. At 21:00 approx i was reboot freenas. Please look attached screeshot. You can see that snapshots was taking every 1 hour but used space is 0 after 11:30 AM! What happend with my freenas? Can i revover data from my pool? It is very important for me. Tomorow my head will take off from my shoulders...

I'm confused? Is your days still on your pool? If it is then how is your data lost? Your screen shot is just of your snapshots not data. And it looks like zero because nothing changed in your data.

i'm confused too. All data still at the pool without last few hours changes. People create, edit and save data on pool all workday from 8:30 AM till 5:30 PM. I dont see now any data from 11:30 am till 17:30. If you look to the screenshot next few snapshots are empty, no any byte all just 0! It is not possible, coz windows read and write any data to disk all time (optimization, indexing etc)! But it is true. I place some files too but don't see it now :(

It looks like if i rollback data but nobody do that.
