So on my PBS server, I use a caching drive for syncing backups to an AWS S3 bucket. Last night, the caching drive went into a read only mode (I believe the disk is worn on endurance, waiting on usb SAS caddy to confirm). The SSD was a Dell enterprise write intensive disk. Could just be a disk things, not blaming pbs. I had another write intensive rated 800gb ssd on hand. Installed the disk, formatted the disk in ext4 with a single partition of the entire disk. Pointed my caching mount at the new disk and added the UUID entry in fstab. However my S3 datastore shows as unavailable in the web UI. Any ideas? Things to check?
Caching drive replacement

Hi, in order to replace the cache drive with a new one, you must:
- Put the datastore into maintenance mode offline, so no task can read/write the datastore
- Perform the replacement on the filesystem backing the local datastore cache disk, including all operation such as formatting filesystem, adapting the systemd mount unit, adapting the backing path if required,...
- Bring the datastore back into maintenance mode read-only
- Perform an s3 refresh, which will update the required local data in the cache by fetching it from the s3 backend.
