Re: [RadosGW] Performance for Concurrency Connections

[Kuo Hugo <tonytkdk@xxxxxxxxx>]

Hi Yehuda, 

Here's my ceph.conf

root@p01:/tmp# cat /etc/ceph/ceph.conf

[global]

fsid = 6e05675c-f545-4d88-9784-ea56ceda750e

mon_initial_members = s01, s02, s03

mon_host = 192.168.2.61,192.168.2.62,192.168.2.63

auth_supported = cephx

osd_journal_size = 1024

filestore_xattr_use_omap = true

[client.radosgw.gateway]

host = p01

keyring = /etc/ceph/keyring.radosgw.gateway

rgw_socket_path = /tmp/radosgw.sock

log_file = /var/log/ceph/radosgw.log

rgw_thread_pool_size = 200

Depends on my conf, the /tmp/radosgw.sock was created while starting radosgw service. 

So that I tried to show up config by :

root@p01:/tmp# ceph --admin-daemon /tmp/radosgw.sock config show

read only got 0 bytes of 4 expected for response length; invalid command?

Is it a bug or operation mistake ? 

root@p01:/tmp# radosgw-admin -v

ceph version 0.61.8 (a6fdcca3bddbc9f177e4e2bf0d9cdd85006b028b)

Appreciate ~

You can do it through the admin socket interface.
Try running something like:
$ ceph --admin-daemon /var/run/ceph/radosgw.asok config show

$ ceph --admin-daemon /var/run/ceph/radosgw.asok config set
rgw_thread_pool_size 200


The path to the admin socket may be different, and in any case can be
set through the 'admin socket' variable in ceph.conf.
