Hi...
Here are a couple of examples based on what we do.
We have not tried all of them so some are just extrapolations based on
the underlying logic. Maybe someone else can correct me if I am wrong. I
the following examples, the root of the filesystem is /cephfs
- Mounting your cephfs filesystem as /cephfs:
# mount -t ceph <MON IP>:/ /cephfs -o name=admin,secretfile=<secret
file>
# df -h
(...)
192.231.127.8:6789:/ 87T 1.4G 87T 1% /cephfs
- Mounting your /cephfs filesystem as /mydata/cephfs (which must exit) then
# mount -t ceph <MON IP>:/cephfs /mydata/cephfs -o
name=admin,secretfile=<secret file>
- Mounting the subtree /cephf/mydir under, for example,
/mydata/cephfs/mydir/ (which must exit) then
# mount -t ceph <MON IP>:/cephfs/mydir /mydata/cephfs/mydir/ -o
name=admin,secretfile=<secret file>
- Mounting the subtree /cephf/mydir under, for example, /mydata/mydir/
(which must exit) then
# mount -t ceph <MON IP>:/cephfs/mydir /mydata/mydir/ -o
name=admin,secretfile=<secret file>
I would also would advise you to create a special user / client to mount
and not use the admin key. Permissions for that user should be something
like
client.mount_user
key: <...>
caps: [mds] allow
caps: [mon] allow r
caps: [osd] allow rw pool=<your cephfs data pool>
Cheers
