Hi all,
I'm trying to dump perf counter when attaching rbd volume into
KVM-Qemu guest machine.
It always failed at creating asok file when starting the guest machine.
Without asok file, I can' use below "ceph perf dump" to get the perf
counters.
The failure log is below:
||AdminSocketConfigObs::init: failed: AdminSocket::bind_and_listen:
||failed to bind the UNIX domain socket to
||'/tmp/ceph-asok_changcheng/ceph-client.libvirt.2388472.93848128323264.asok':
||(13) Permission denied
Does anyone know how to sovle it?
Sovled: Add user "libvirt-qemu" into
the user's group who created "/tmp/ceph-asok_changcheng/"
