Hello,
today I noticed some strange things on my 3 machines with each 1 hard disk, 1 osd, 1 mds, 1 mon. They are named r1-9, r1-10, r1-11.
In the output of "ceph mds dump" (full output below), in see some phantom mds:

why do r1-9 and r1-10 appear twice, and why does r1-11 appear 5 times? Is it a problem, how to fix it ?
I also had a 2 blacklisted OSDs (out of 3). Could it be because I restarted them many times in a row? How to clear the blacklisted status by hand (if I don't want to wait the delay)?
Thanks, Fred
