All;
When I went to check Wido's suggestion, I found the MDS daemons would start
successfully. I obviously found no significant time differences.
Sorry for making a mountain out of a mole-hill.
Thank you,

We are in the middle of upgrading our primary cluster from 14.2.5 to 14.2.8. Our cluster
utilizes 6 MDSs for 3 CephFS file systems. 3 MDSs are collocated with MON/MGR, and 3 MDSs
are collocated with OSDs.
At this point we have upgraded all 3 of the MON/MDS/MGR servers. The MDS on 2 of the 3 is
currently not working, and we are seeing the below log messages.

2020-03-06 11:13:26.184 <> 1 mds.<daemon> suicide! Wanted state up:boot
Any ideas?
Double check: Is the time correct on all the machines?
cephx can have issues if there is a clock issue.
