1471 | tasks: | |
1472 | - ceph: | |

1495 | tasks: | |
1496 | - ceph: | |
1497 | path: /home/sage/ceph | |
1498 | ||
1499 | To capture code coverage data, use:: | |
1500 | ||
1501 | tasks: | |
1502 | - ceph: | |
1503 | coverage: true | |
1504 | ||
1505 | To use btrfs, ext4, or xfs on the target's scratch disks, use:: | |
1506 | ||
1507 | tasks: | |
1508 | - ceph: | |
1509 | fs: xfs | |
1510 | mkfs_options: [-b,size=65536,-l,logdev=/dev/sdc1] | |
1511 | mount_options: [nobarrier, inode64] | |
1512 | ||
1513 | Note, this will cause the task to check the /scratch_devs file on each node | |
1514 | for available devices. If no such file is found, /dev/sdb will be used. | |
1515 | ||
1516 | To run some daemons under valgrind, include their names | |
1517 | and the tool/args to use in a valgrind section:: | |
1518 | ||
1519 | tasks: | |
1520 | - ceph: | |
1521 | valgrind: | |
1522 | mds.1: --tool=memcheck | |
1523 | osd.1: [--tool=memcheck, --leak-check=no] | |
1524 | ||
1525 | Those nodes which are using memcheck or valgrind will get | |
1526 | checked for bad results. | |
1527 | ||
1528 | To adjust or modify config options, use:: | |
1529 | ||
1530 | tasks: | |
1531 | - ceph: | |
1532 | conf: | |
1533 | section: | |

1540 | conf: | |
1541 | mds.0: | |

1543 | other key: other value | |
1544 | client.0: | |
1545 | debug client: 10 | |
1546 | debug ms: 1 | |
1547 | ||
1548 | By default, the cluster log is checked for errors and warnings, | |
1549 | and the run marked failed if any appear. You can ignore log | |
1550 | entries by giving a list of egrep compatible regexes, i.e.: | |
1551 | ||
1552 | tasks: | |
1553 | - ceph: | |
1554 | log-whitelist: ['foo.*bar', 'bad message'] | |
1555 | ||
1556 | To run multiple ceph clusters, use multiple ceph tasks, and roles | |
1557 | with a cluster name prefix, e.g. cluster1.client.0. Roles with no | |
1558 | cluster use the default cluster name, 'ceph'. OSDs from separate | |
1559 | clusters must be on separate hosts. Clients and non-osd daemons | |
1560 | from multiple clusters may be colocated. For each cluster, add an | |
1561 | instance of the ceph task with the cluster name specified, e.g.:: | |
1562 | ||
1563 | roles: | |
1564 | - [mon.a, osd.0, osd.1] | |
1565 | - [backup.mon.a, backup.osd.0, backup.osd.1] | |
1566 | - [client.0, backup.client.0] | |
