I'm still running Emperor, but I'm not seeing that behavior. My ceph.conf is pretty similar:
[global]
mon initial members = ceph0
cluster network = 10.130.0.0/16
osd pool default flag hashpspool = true
osd pool default min size = 2
osd pool default size = 3
public network = 10.129.0.0/16
[osd]
osd journal size = 6144
osd mkfs options xfs = -s size=4096
osd mkfs type = xfs
osd mount options xfs = rw,noatime,nodiratime,nosuid,noexec,inode64
For the daemon configs, you can query a running daemon to see what it's config params are:
root@ceph0:~# ceph daemon osd.0 config get 'osd_op_threads'
{ "osd_op_threads": "2"}
root@ceph0:~# ceph daemon osd.0 config get 'osd_scrub_load_threshold'
{ "osd_scrub_load_threshold": "0.5"}
ceph tell osd.\* --inject_args '--osd_op_threads 10'

Hello,
Consider this rather basic configuration file:

mon_initial_members = ceph-01, comp-01, comp-02

auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
filestore_xattr_use_omap = true
mon_osd_downout_subtree_limit = host
public_network = 10.0.0.0/8
osd_pool_default_pg_num = 2048
osd_pool_default_pgp_num = 2048
osd_crush_chooseleaf_type = 1
[osd]
osd_mkfs_type = ext4
osd_mkfs_options_ext4 = -J size=1024 -E lazy_itable_init=0,lazy_journal_init=0
osd_op_threads = 10
osd_scrub_load_threshold = 2.5
filestore_max_sync_interval = 10

Let us slide the annoying fact that ceph ignores the pg and pgp settings
when creating the initial pools.
And that monitors are preferred based on IP address instead of the
sequence they're listed in the config file.
Interestingly ceph-deploy correctly picks up the mkfs_options but why it
fails to choose the mkfs_type as default is beyond me.
The real issue is that the other three OSD setting are NOT picked up by
ceph on startup.
But they sure are when moved to the global section.
Anybody else seeing this (both with 0.80.1 and 0.80.6)?
Regards,
Christian
