I'm trying to fix the Longhorn issue I mentioned further up. I'm noticing that the longhorn config appears to be pointing at the wrong disk, somehow.

harvester-01:/home/rancher # blkid /dev/sdb 
/dev/sdb: LABEL="HARV_LH_DEFAULT" UUID="543d5c25-6d15-4d9f-9be5-27a3dedd8208" BLOCK_SIZE="4096" TYPE="ext4" 
harvester-01:/home/rancher # cat /var/lib/harvester/defaultdisk/longhorn-disk.cfg 
{"diskUUID":"9a3c4db0-3354-4f16-b102-04b18e187630"}

The diskUUID in the config doesn't match that of the disk it should be using, or any other disk for that matter
