Mount nfs client (requires nfs server export like knfsd or ganesh)
|
|
|
|
Example that mounts a single nfs client::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- kclient: [client.0]
|
|
- knfsd: [client.0]
|
|
- nfs:
|
|
client.1:
|
|
server: client.0
|
|
- interactive:
|
|
|
|
Example that mounts multiple nfs clients with options::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- kclient: [client.0, client.1]
|
|
- knfsd: [client.0, client.1]
|
|
- nfs:
|
|
client.2:
|
|
server: client.0
|
|
options: [rw,hard,intr,nfsvers=3]
|
|
client.3:
|
|
server: client.1
|
|
options: [ro]
|
|
- workunit:
|
|
clients:
|
|
client.2:
|
|
- suites/dbench.sh
|
|
client.3:
|
|
- suites/blogbench.sh
|
|
|
|
It is not recommended that the nfs client and nfs server reside on the same node. So in the example above client.0-3 should be on 4 distinct
|
|
nodes. The client nfs testing would be using only client.2 and client.3.
