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']
To run multiple ceph clusters, use multiple ceph tasks, and roles
with a cluster name prefix, e.g. cluster1.client.0. Roles with no
cluster use the default cluster name, 'ceph'. OSDs from separate
clusters must be on separate hosts. Clients and non-osd daemons
from multiple clusters may be colocated. For each cluster, add an
instance of the ceph task with the cluster name specified, e.g.::
roles:
- [mon.a, osd.0, osd.1]
- [backup.mon.a, backup.osd.0, backup.osd.1]
- [client.0, backup.client.0]
tasks:
- ceph:
cluster: ceph
- ceph:
cluster: backup
