My cache SSD was running hot and throwing thermal alerts, even when the rest of the drives and server were running cool. The logs were showing some errors, and the drive is nearly six years old so I decided to replace it and move to a cache pool in RAID1.
Have added the two new drives (one brand new, one that was lying spare) and tried to balance in the Cache settings but it aborts. Another forum post said it might be down to errors and the existing SSD should be scrubbed, and then the balance would work so I tried that. Scrub also aborts, so I'm a little stuck.
Any help anyone could offer would be appreciated. Happy to work in the terminal if given commands to paste.
Diagnostics attached.
