Description

For MDS id other than the default (a,b,c), ceph-mds displays 'starting mds.otherid at -', but the mds process actually shuts down (goto shutdown) without printing any informative message. This looks as if the new process is started and running, but actually it is not.

In addition, Is there a better way to deal with this situation? Like don't attempt the starting?

$ ./bin/ceph-mds -i otherid
starting mds.otherid at -

Where do you get "default"? MDS ids have no default names.

, ceph-mds displays 'starting mds.otherid at -', but the mds process actually shuts down (goto shutdown) without printing any informative message. This looks as if the new process is started and running, but actually it is not.

We need information on how the MDS shuts down. I assume you turned debugging all the way up?
