Hi,
my NAS crashed after usb flash drive accidentally removed then i rebooted it and couldn't load OS again (kernel panic)
i changed the usb flash drive to a new one, upgraded RAM to 8GB and installed nas 9.2.1.7, after the install i got stuck at "GRUB" with the cursor blinking then i tried to upgrade to 9.3-M4 (i know its not a stable release so i shouldn't do that but i gave it a shot).
I was still stuck at GRUB so i changed then the mainboard and i was able to boot. i could import the volume but my 3 datasets are empty (Sites, Backups, Dados).
DF -h shows the correct usage size (note that NAS has 6.2TB used space:

any ideas how i could recover my data? i have no snapshots, since a huge amount of data i didn't yet get another server for replication.
