Tasks:
- [x] 1. Order replacement RAID controller battery Areca arc-6120BA
- [x] 2. One-off tar backup of all users to norbert.
- [x] 3. Offline (single user mode) run
xfs_repair - [x] 4. Manually Trigger RAID Controller RAID5 patrol read + repair to force remap bad sectors (across disks)
- [ ] 5. Replace RAID controller battery during site visit.
- [ ] 6. Replace Failing Disk (2TB spinning rust or entry level 2TB SDD) during site visit.
Option to Manually trigger patrol + repair (via archttp64)

tar completed backup of all the users except: ant, harrywood and mvexel for who limited backups were created because they have millions of tiny cache files which would have significantly delayed completion.
Disk still causing minor issues, but fixed the system crashing. Th areca controller was not compatible with Ubuntu 22.04 kernel (5.15), reverted to Ubuntu 20.04 kernel (5.13) and the crashes have stopped.
Not going to replace disk. Faffy server is now up and will replace errol shortly.
