If you look at the "ceph --help" output you'll find some commands for
removing MDSes from the system.
Yes, this works for all but the last mds..
[root@mds01 ~]# ceph mds rm 35632 mds.mds03
Error EBUSY: cannot remove active mds.mds03 rank 0
I stopped the daemon, checked the process was stopped, even did a
shutdown of that mds server, I keep getting this message and am unable
to remove the fs ..
log file has this:
2015-04-23 16:14:05.171450 7fa9fe799700 -1 mds.0.4 *** got signal
Terminated ***
2015-04-23 16:14:05.171490 7fa9fe799700 1 mds.0.4 suicide. wanted
