VM Wont start and BTRFS Errors in log.

[NeoDude]

Hey folks, hope you can help me out on this one.

My PfSense VM hung so I hit restart and get hit with the following error message.....

 

unable to open /mnt/user/vDisks/PfSense/vdisk1.img: Read-only file system

 

My log is also full of BTRFS errors (Although no errors showing next to cache drives in the GUI).

Is this a disk failure? or something else? I thought the idea behind a pool was for HA, i.e. if a disk goes corrupt, everything keeps running?

Anyhoo, any ideas? Ideally one that keeps my vdisk entact. Luckily I have a hardware PfSense backup box, but it can only manage half the throughput.

Diagnostics attached, thanks in advance

mmm, seems all it needed was a reboot.

Thanks to anybody that took the time anyways. If there's any other glaring issues in my Diags I'd be happy for the pointers

Filesystem corruption on cache and it went read-only, it will likely happen again, make sure backups are up to date or preemptively backup and re-format.

If you do this, you might want to do a memtest to check if the root cause is not there.
