| Hi Josy,
this is correct.
Just make sure that your current user as well as the user for your VMs (if you are using a VM environment) are allowed to write to this directory.
Also make sure that /var/run/ceph exists.
Once you have fixed the permissions problem and made sure that the path where you want to create the socket file exists it will be OK.
Note that the socket file can be created anywhere. So you could actually position the parameter as admin_socket = “./my-client.asok” just for the purpose of a test

I think it is permission error, because when running ceph -s it shows this error at the top ------------- $ ceph -s 2017-10-17 15:53:26.132180 7f7698834700 -1 asok(0x7f76940017a0) AdminSocketConfigObs::init: failed: AdminSocket::bind_and_listen: failed to bind the UNIX domain socket to '/var/run/ceph/ceph-client.admin.29983.140147265902928.asok': (13) Permission denied cluster: id: de296604-d85c-46ab-a3af-add3367f0e6d health: HEALTH_OK ------------ Selinux is disabled in the server. Also I changed ownership of /var/run/ceph to the ceph user. Still no luck.

Hi,
I am running the command from the admin server.
Because there are no asok file in the client server
ls /var/run/ceph/ lists no files in the client server.
Most likely a permissions or SElinux/AppArmor issue where the librbd
client application cannot write to the directory.
As Jason points it out you also need to make sure that your restart the
client connection for the changes in the ceph.conf file to take effect.
You mean restart the client server ?
(I am sorry, this is something new for me. I have just started learning
ceph.)
Assuming this is for QEMU, QEMU is the librbd client so you would have
to stop/start the VM to pick up any configuration changes (or perform
a live migration to another server).

Hi Josy,
just a doubt but it looks like your ASOK file is the one from a Ceph
Manager. So my suspicion is that you may be running the command from the
wrong machine.
To run this command, you need to ssh into the machine where the client
connection is being initiated.
But may be I am wrong regarding your exact connection point.

Thanks for the reply.
I added rbd_non_blocking_aio = false in ceph.conf and pushed the admin file
to all nodes.
-----
[client]
admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok
log file = /var/log/ceph/client.log
debug rbd = 20
debug librbd = 20
rbd_non_blocking_aio = false
------
However the config show command still shows it as true.
-----------
[cephuser@ceph-las-admin-a1 ceph-cluster]$ sudo ceph --admin-daemon
/var/run/ceph/ceph-mgr.ceph-las-admin-a1.asok config show | grep
"rbd_non_blocking_aio"
"rbd_non_blocking_aio": "true",
-----------
Did I miss something ?

Hi
syntax uses the admin socket file : ceph --admin-daemon
/var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok config get rbd_cache
Should be /var/run/ceph/ceph.client.admin.$pid.$cctid.asok if your
connection is using client.admin to connect to the cluster and your cluster
name is set to the default of ceph. But obviously can’t know from here the
PID and the CCTID you will have to identify.
You can actually do a ls /var/run/ceph to find the correct admin socket file

Hi,
I am following this article :
http://ceph.com/geen-categorie/ceph-validate-that-the-rbd-cache-is-active/
I have enabled this flag in ceph.conf
[client]
admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok
log file = /var/log/ceph/
But the command to show the conf is not working :
[cephuser@ceph-las-admin-a1 ceph-cluster]$ sudo ceph --admin-daemon
/etc/ceph/ceph.client.admin.keyring config show
admin_socket: exception getting command descriptions: [Errno 111] Connection
