Thanks, Jason-- Turns out AppArmor was indeed enabled (I was not aware of that). Disabled it and now I see the socket but it seems to only be there temporarily while some client app is running.
The original reason I wanted to use this socket was that I am also using an rbd images thru kvm and I wanted to be able to flush and invalidate the rbd cache as an experiment. I would have thought the socket would get created and stay there as long as kvm is active (since kvm is using librbd). But even when I access the rbd disk from the VM, I don't see any socket created at all. -- Tom > -----Original Message----- > From: Jason Dillaman [mailto:jdill...@redhat.com] > Sent: Thursday, June 30, 2016 6:15 PM > To: Deneau, Tom <tom.den...@amd.com> > Cc: ceph-users <ceph-us...@ceph.com> > Subject: Re: [ceph-users] rbd cache command thru admin socket > > Can you check the permissions on "/var/run/ceph/" and ensure that the user > your client runs under has permissions to access the directory? > If the permissions are OK, do you have SElinux or AppArmor enabled and > enforcing? > > On Thu, Jun 30, 2016 at 5:37 PM, Deneau, Tom <tom.den...@amd.com> wrote: > > I was following the instructions in > > > > https://www.sebastien-han.fr/blog/2015/09/02/ceph-validate-that-the-rb > > d-cache-is-active/ > > > > because I wanted to look at some of the rbd cache state and possibly > > flush and invalidate it > > > > My ceph.conf has > > [client] > > rbd default features = 1 > > rbd default format = 2 > > admin socket = /var/run/ceph/$cluster-$type.$id.$pid.$cctid.asok > > log file = /var/log/ceph/ > > > > I have a client only node (no osds) and on that node I ran fio with the > librbd engine, which worked fine.
