As of Ceph Luminous 12.2.1 the maximum number of PGs per OSD before the
|
|
monitor issues a warning has been reduced from 300 to 200 PGs. In addition,
|
|
Ceph now fails with an error rather than a warning in the case of exceeding
|
|
the max value.
|
|
In order to allow Kolla to continue to be used out of the box we have
|
|
reduced the default values for pg_num and pgp_num from 128 to 8. This will
|
|
allow a deploy of Kolla with all possible services enabled and then some,
|
|
with the minimum recommended three OSDs. Operators are *highly*
|
|
recommended to review the Ceph documentation regarding these values in
|
|
order to ensure optimal performance for their own cluster.
