Hi All,

Note: deployed ceph cluster using ceph-deploy utility ..version 2.1.0
Out those three virtual machine, two machines are being used a client also,
using ceph posix filesystem to store data to the cluster.
followed following commands.
Ran below command on the main machine, where all commands or ceph-deploy is
installed.
sudo ceph auth get-or-create client.user mon 'allow r' mds 'allow r, allow
rw path=/home/cephfs' osd 'allow rw pool=cephfs_data' -o
/etc/ceph/ceph.client.user.keyring
As Robert mentioned the 'path=' here should be the relative path from
the root of the cephfs instead of your local fs.
Ran these two on the client.
sudo mkdir /mnt/mycephfs $ sudo mount -t ceph
ubuntu1:6789,ubuntu2:6789,ubuntu3:6789:/ /mnt/mycephfs -o
name=user,secret=AQBxnDFdS5atIxAAV0rL9klnSxwy6EFpR/EFbg==
And you just created the mds auth caps for "/home/cephfs" path, but you
were mounting the '/' path with that caps.
Thanks

After this when we are trying to right to the mount path../mnt/mycephfs..
it is giving permission denied.
How can we resolve this?
I tried disabling cephx, but still ceph-deploy mon create-inital is failing
as key mon not found?
