Set up and tear down a Ceph cluster.

|
|
For example::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- interactive:
|
|
|
|
You can also specify what branch to run::
|
|
|
|
tasks:
|
|
- ceph:
|
|
branch: foo
|
|
|
|
Or a tag::
|
|
|
|
tasks:
|
|
- ceph:
|
|
tag: v0.42.13
|
|
|
|
Or a sha1::

|
|
tasks:
|
|
- ceph:
|
|
sha1: 1376a5ab0c89780eab39ffbbe436f6a6092314ed
|
|
|
|
Or a local source dir::
|
|
|
|
tasks:
|
|
- ceph:
|
|
path: /home/sage/ceph
|
|
|
|
To capture code coverage data, use::
|
|
|
|
tasks:
|
|
- ceph:
|
|
coverage: true
|
|
|
|
To use btrfs, ext4, or xfs on the target's scratch disks, use::
|
|
|
|
tasks:
|
|
- ceph:
|
|
fs: xfs
|
|
mkfs_options: [-b,size=65536,-l,logdev=/dev/sdc1]
|
|
mount_options: [nobarrier, inode64]
|
|
|
|
Note, this will cause the task to check the /scratch_devs file on each node
|
|
for available devices. If no such file is found, /dev/sdb will be used.
|
|
|
|
To run some daemons under valgrind, include their names
|
|
and the tool/args to use in a valgrind section::
|
|
|
|
tasks:
|
|
- ceph:
|
|
valgrind:
|
|
mds.1: --tool=memcheck
|
|
osd.1: [--tool=memcheck, --leak-check=no]
|
|
|
|
Those nodes which are using memcheck or valgrind will get
|
|
checked for bad results.
|
|
|
|
To adjust or modify config options, use::
|
|
|
|
tasks:
|
|
- ceph:
|
|
conf:
|
|
section:
|
|
key: value
|
|
|
|
For example::
|
|
|
|
tasks:
|
|
- ceph:
|
|
conf:
|
|
mds.0:
|
|
some option: value
|
|
other key: other value
|
|
client.0:
|
|
debug client: 10
|
|
debug ms: 1
|
|
|
|
By default, the cluster log is checked for errors and warnings,
|
|
and the run marked failed if any appear. You can ignore log
|
|
entries by giving a list of egrep compatible regexes, i.e.:
|
|
|
|
tasks:
|
|
- ceph:
|
|
log-whitelist: ['foo.*bar', 'bad message']
