This was indeed the issue: the configuration file named the MDS as `mds.0`
which is not allowed (error message was "MDS names may not start with
a numeric digit.")
so the MDS daemon kept "committing suicide" (unnoticed at the start,
since the daemon seems
to start correctly and dies later on).

Thank you all for the help!

Sorry, I copy+paste'd the wrong line.  Yes, I tried with `mon001` as well.
It fails eventually (takes much longer) with error 5.

In that case you're probably using an old kernel.  Sufficiently old
kernels will not work with new ceph clusters.  Check if it works with
ceph-fuse.

Unless mds001 happens to also be a mon node, that's the problem -- the
addresses in the mount command are supposed to be the mons.

Re: [ceph-users] Cannot mount Ceph FS

[Jaime Ibar]

Hi,

I'd say there is no mds running

$ ceph mds stat
e47262: 1/1/1 up {0=ceph01=up:active}, 2 up:standby

$ ceph -s

[...]

  fsmap e47262: 1/1/1 up {0=ceph01=up:active}, 2 up:standby

[...]

Is mds up and running?

Jaime

You need a running MDS daemon for CephFS.
