This commit implements this corner case during osd-prepare job. ``` The encrypted block is not opened, this is an extreme corner case The OSD deployment has been removed manually AND the node rebooted So we need to re-open the block to re-hydrate the OSDInfo. Handling this case would mean, writing the encryption key on a temporary file, then call luksOpen to open the encrypted block and then call ceph-volume to list against the opened encrypted block. We don't implement this, yet and return an error. ``` When underlying PVC for osd are CSI provisioned, the encrypted device is closed when PVC is unmounted due to osd pod being deleted. Therefore, this may occur more frequently and needs to be handled. This commit implements the fix for the same. Signed-off-by: Rakshith R <rar@redhat.com>
