Teuthology uses /tmp/cephtest/ as the scratch test directory for
a run. This patch replaces /tmp/cephtest/ everywhere with a
per-run directory: {basedir}/{rundir} where {basedir} is a directory
configured in .teuthology.yaml (/tmp/cephtest if not specified),
and {rundir} is the name of the run, as given in --name. If no name
is specified, {user}-{timestamp} is used.
To get the old behavior (/tmp/cephtest), set test_path: /tmp/cephtest
in .teuthology.yaml.
This change was modivated by #3782, which requires a test dir that
survives across reboots, but also resolves #3767.

Export/Unexport a ``nfs server`` client.
|
|
|
|
The config is optional and defaults to exporting on all clients. If
|
|
a config is given, it is expected to be a list or dict of clients to do
|
|
this operation on. You must have specified ``ceph-fuse`` or
|
|
``kclient`` on all clients specified for knfsd.
|
|
|
|
Example that exports all clients::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- kclient:
|
|
- knfsd:
|
|
- interactive:
|
|
|
|
Example that uses both ``kclient` and ``ceph-fuse``::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- ceph-fuse: [client.0]
|
|
- kclient: [client.1]
|
|
- knfsd: [client.0, client.1]
|
|
- interactive:
|
|
|
|
Example that specifies export options::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- kclient: [client.0, client.1]
|
|
- knfsd:
|
|
client.0:
|
|
options: [rw,root_squash]
|
|
client.1:
|
|
- interactive:
|
|
|
|
Note that when options aren't specified, rw,no_root_squash is the default.
|
|
When you specify options, the defaults are as specified by exports(5).
|
|
|
|
So if empty options are specified, i.e. options: [] these are the defaults:
|
|
ro,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,
|
|
no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534
