Unknown filesystems and mount error 5

[oliversl]

Hi,
I have a small FreeNAS for TimeMachine on a VirtualBox VM

A few days ago I got an error while booting, Grub rescue, unknown filesystem.

So I added a new boot drive, 16GB, but can not boot until I disconnect the original boot drive of 10GB.

After I re-installed FreeNAS 9.1 and upgraded to 11.1, I get the message on the volume about not been able to get the available space. So I think that maybe used the 1st boot drive of 10Gb as part of the pool or that the ifs pool run out of disk space.

When I reconnect the 10Gb boot drive again, I get the error about mount error 5.

So, my questions are:
- is there way to fsck that 10GB boot drive?
- could it be that I run out of disk space on the ifs pool? Should I add another virtual hard drive in order to fix it?

I attach a screenshot since I can not copy&past the text from the virtual box VM

Regards,
Oliver

hi, I solved my issue by:
- installing a new boot drive, leaving only both data drives
- restore the configuration from my backup
- install the correct version of FreeNAS that I had (11.1 U7), and then update to the latest update I had

Thats all that was needed, regards
