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.

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

signalz

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

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.
