Re: Can't Mount CephFS

[Scott Kinder <skinder@xxxxxxxxxxx>]

Turns out, this was a configuration error on my part. I had no MDS defined. Fixed that, now I can mount ceph on remote hosts.

So on another server, which never mounted the ceph FS from 10.122.32.21, it still outputs the mount error 5. I see the following in syslog:

libceph: mon0 10.122.32.23:6789 session established

libceph: client0 fsid 1012cf1b-29b7-40d2-a5a0-75ede1b8f885

Same mount command as I previously posted.

I do not, that server is offline. Though at one point, I did have a monitor running at that IP, and had mounted the ceph FS from that server on the server which is exhibiting the connectoin failed error. The command I'm using to mount is:

mount -t ceph 10.122.32.23:/ /mnt/

In the above mon connect failure, its looking for 10.122.32.21.  Do
you have a monitor running there as well?  What mount command are you
using?
