["Mr.Salvatore Rapisarda" <salvorapi@xxxxxxxx>]

Hi,

i have a ceph cluster with 3 nodes on Ubuntu 12.04.3 LTS and ceph 
version 0.72.1

My configuration is the follow:

* 3 MON
  - XRVCLNOSTK001=10.170.0.110
  - XRVCLNOSTK002=10.170.0.111
  - XRVOSTKMNG001=10.170.0.112
* 3 OSD
  - XRVCLNOSTK001=10.170.0.110
  - XRVCLNOSTK002=10.170.0.111
  - XRVOSTKMNG001=10.170.0.112
* 1 MDS
  - XRVCLNOSTK001=10.170.0.110

All it's ok...

If i try to mount cephfs on first node 10.170.0.112, used for cluster 
deploy process, there is no problem.
But if i try to mount cephfs on second node 10.170.0.110 or third node 
10.170.0.111 i have a "mount error 12 = cannot allocate memory"

-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#
root@XRVCLNOSTK002:/mnt# mount -t ceph XRVCLNOSTK001:6789:/ /mnt/nova -o 
name=admin,secret=my_secret_key

mount error 12 = Cannot allocate memory

Thanks.

Salvo.
