It could be of use especially for SSD devices used for journals.
Unfortunately there seems to be no standard in reporting SSD cell life
remaining, but if there were some subset of devices supported my thought
is that the journals could be moved to another drive once write life
reaches some level, like 5%. Or some method to shutdown the
host(/affected OSDs), replace the SSD, then bring them back online with
the new journal device.
Just thinking out loud, as usual :)
