Re: if partition name changes, will ceph get corrupted?

Not sure if this answers your question, but when you start the osd that's remapped, ceph will not be able to find the correct key and refuse to use that osd.

If a partition name such as "/dev/sdd" changes to "/dev/sde" and ceph was already mapped to the old "/dev/sdd", how will CEPH react? For example, would it get corrupted, or notice a problem and fail remove that one OSD from cluster or somehow automatically re-adapt?

FYI: I ask because we added a new hard disk (disk #3) in the middle of a 8-disk server and I'm not sure if the PERC RAID controller and/or the Centos 6.5 OS will rename the original parititions so that the partitions are names alphabetically or just add a new paritition (/dev/sdh) for this 3rd disk.
