Mounting failed with error 5

[signalz]

My pfSense 2.7 VM suddenly won't boot. Last shut down was clean, though the host (Ubuntu 22.04) has crashed with the pfSense VM running before. I never noticed any apparent problems because of that. The hard drive the disk image is on doesn't seem to be having problems either.

What do I do now? Is this recoverable? I'm having a hard time getting anywhere is this shell.

I would try to boot into single user mode and run a ZFS scrub:

Is there something else going on, or am I just very bad at FreeBSD? What out of anything on the screen is the pool name?

[stephenw10]

Run: zpool status to see it. By default it's pfSense.

[stephenw10]

For example:

23.09-RELEASE][admin@5100.stevew.lan]/root: zpool status
  pool: pfSense
 state: ONLINE
status: Some supported and requested features are not enabled on the pool.
	The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
	the pool may no longer be accessible by software that does not support
	the features. See zpool-features(7) for details.
config:

	NAME        STATE     READ WRITE CKSUM
	pfSense     ONLINE       0     0     0
	  ada0p3    ONLINE       0     0     0

errors: No known data errors

Both zpool status and zpool scrub pfSense return Invalid file system specification

[stephenw10]

Hmm, probably going to be easier to just reinstall but you could try geom part list just to make sure it sees the partition at all.
Very unusual to a ZFS failure like that. I'd have to assume it's some filesystem issue at the hypervisor level.

[signalz]

Thanks for your help. geom part list says the same thing. I'll reinstall.
