It should be used to disable health warnings about number of PGs
being too low if some pools have very few objects bringing down
the average number of objects per pool. This happens when running RadosGW.
The default is 10 and since the warnings only occur with some use cases,
the default here is 10 as well. Set to 20 or more to silence the warnings.
Currently, the fetch directory is created in your working directory
(where ansible is run from). We prefer to not keep any state in this
directory and would prefer to have the fetch directory configurable so
we can store it outside of our code checkout.
This commit creates a new variable in each role called
`fetch_directory` (defaulting to the previous value of 'fetch/'), and
then updates each reference to 'fetch' to use the new variable instead.
Closes issue #383
When multiple monitor hosts attempt to create the fetch directory there
is the potential for the task to fail with:
"OSError: [Errno 17] File exists: 'fetch'"
This appear to be an issue with the file module trying to create the
same directory at the same time when the tasks has been delegated to a
single host.
This commit enables run_once on the affected task which should address
the issue.
This is a rare case but it happens. Since we're just calling
`monitor_interface` and not `hostvars[host]['monitor_interface'],
an error may occur when the current host's interface does not
exist on the other hosts. (eg. eth0 exists for node0, but it does
not exist on node1 and node2)
Fix for this is to use hostvars[host]['monitor_interface']
I'm removing the ceph paritition check from `activate osd(s) when device
is a disk` because the ceph parition does not exist when parted was
registered (on a fresh install). This was causing the activate step to
be skipped.
Currently the OpenStack pools that get created use the default pg_num.
This commit updates the ceph-mon role to allow the pg_num for each pool
to be customised.
Fix back the rolling update playbook.
However every single time the playbook will run it will check for new
packages and install the latest ones. I don't think this is always the
desired behaviour. We need to find a way to conciliate both...

Fix the logic for the mandatory devices check so that it applies to
raw_multi_journal and journal_collocation scenarios separately.
This fails otherwise because whichever var is "first" in the or is most
likely undefined.
This will likely one day or another break something. If ceph-disk
complains about a disk just use the purge-cluster.yml playbook first as
it will wipe all the devices.

The logic was broken here for repeated runs. We only want to run
'ceph-disk prepare' when the disk does not contain a ceph partition, is
not a partition, and raw_multi_journal is set. Previously it would
attempt to run 'ceph-disk prepare' when there was a ceph partition
because the second half of the 'or' was still true since it isn't a
partition.
Following the best practice, we don't create a key from the monitor but
we really on the initial keys created by the mons to bootstrap each
daemon.
