Hello,
I was unsuccessful in mounting CephFS with kernel on Ubuntu (it was
senta02) today. Here's the command I was using to mount -
$ sudo mount -t ceph 172.21.9.32:40886:/ /mnt/kcephfs1 -o
name=admin,secret=AQCpa8ld1ahOIhAACPhh2qncfv0LkuI6+kUsEA==
mount: mount 172.21.9.32:40886:/ on /mnt/kcephfs1 failed: Connection timed out
I got the following message in dmesg logs -
[328388.882391] libceph: mon0 172.21.9.32:40886 feature set mismatch,
my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000
[328388.894612] libceph: mon0 172.21.9.32:40886 missing required
protocol features
Port 40886 spoke msgv1, so AFAIS, the command looks fine. I tried
40885 too but I got "Connection timed out" on stdout and "socket
closed (con state CONNECTING) in dmesg logs as usual. I also tried
running cluster on loopback/localhost and used 127.0.0.1:40917:/ but
even that was unsuccessful.
To make sure that I am not missing anything I tried the same thing on
Fedora 29 and the mount was successful. I've attached logs containing
mount commands, dmesg logs and keyring for cluster. I was using this
branch to build and run Ceph cluster -

Thanks,
