Hello Gregory, Thanks for the quick response. Does this mean that the rados python library is out of date? create_pool in rados.py (https://github.com/ceph/ceph/blob/master/src/pybind/rados.py#L535)
only requires a pool_name….doesn’t even offer pg_num as an optional argument. Thank you, -Jason From: Gregory Farnum [mailto:greg@xxxxxxxxxxx]
Just from memory, I think these values are only used for the initial pool creations when the cluster is first set up.

library isn't using ceph.conf's pg_num and pgp_num settings during pool creation. My ceph.conf: [global] auth_service_required = cephx filestore_xattr_use_omap = true auth_client_required = cephx auth_cluster_required = cephx mon_host = 64.0.1.210,64.0.1.211 public_network = 64.0.1.192/26 mon_initial_members = MON05, MON06 fsid = 91eda869-9a34-4f74-8189-7d5fb6952f4a osd pool default pg num = 256 osd pool default pgp num = 256 In python, using the above ceph.conf, conf_get returns the correct pg_num and I am able to create
the pool. [root@DCOS01 lib]# python >>> import rados >>> cluster = rados.Rados(conffile='/etc/ceph/ceph.conf') >>> cluster.conf_get('osd pool default pg num') '256' >>> cluster.connect() >>> cluster.create_pool('PE-TEST4') After the pool is created via the librados python library, I check the pg_num of the pool and it's
8; not 256. [root@DCOS01 lib]# ceph osd pool get PE-TEST4 pg_num pg_num: 8 Has anyone else run into this issue? Am I missing something? I know I could just spawn a subprocess call to the ceph command line utility,
but I would like to avoid that in the name of a cleaner python integration. Your assistance is greatly appreciated. Thank you, - Jason _______________________________________________ |
