Error Booting System -- 2.4.4 (after upgrade)

[wangel]

So I just moved my pfsense firewall to my new server room, and after turning it back on, it failed to boot.
I shut the system down before moving it. It was a full power off.

It boots the menu screen, but trying to load the kernel fails with:

zfs io error all block copies unavailable.

Of course I start to panic ... but then I realize I can boot kernel.old ... which booted fine.

Once I got the system booted, I ran: zpool scrub zroot ... which came back with an error. Running:

zpool status -v gives me this:

[2.4.4-RELEASE][admin@fw.alteredreality.cc]/root: zpool status -v

pool: zroot

state: ONLINE

status: One or more devices has experienced an error resulting in data

corruption. Applications may be affected.

action: Restore the file in question if possible. Otherwise restore the

entire pool from backup.

see: http://illumos.org/msg/ZFS-8000-8A

scan: scrub repaired 0 in 0h0m with 1 errors on Tue May 28 19:53:08 2019

config:

NAME STATE READ WRITE CKSUM

zroot ONLINE 0 0 1

ada0p4 ONLINE 0 0 25

errors: Permanent errors have been detected in the following files:

//boot/kernel/kernel

Obviously it looks like my kernel is corrupt / bad. My question is. How do I fix it?

Can I just copy kernel.old over kernel? lol. I doubt this would work.

Anyways, this is a fairly new machine -- however the ssd in it is 100% new, maybe only 3months old at that ... and it's not like it gets a ton of data writes. Also, SmartData reports everything is ok.

Thanks guys!

A clean reinstall with 'Recover config.xml' option is probably the fastest way: https://docs.netgate.com/pfsense/en/latest/backup/automatically-restore-during-install.html
Before the reinstall take a Backup first just in case...
