Block devices can move between reboots. In corner cases, an OSDs block
device might move to a lower-indexed device while the previous device
does not exist. For example, an OSD on /dev/sde might move to /dev/sdd
on reboot if the original /dev/sdd died. There would be no /dev/sde
after that.
Users report that NVMe drives commonly change names, even when there are
no disk failures.
For these cases, ensure the activate script properly handles cases where
the previous disk is not present on the node and where the OSD is still
available on a different disk.
