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?
I've looked below webpage without solution.
https://docs.ceph.com/docs/master/rbd/libvirt/
My host OS info is below:
||cat /etc/os-release
||NAME="Ubuntu"
||VERSION="18.04.1 LTS (Bionic Beaver)"
||ID=ubuntu
||ID_LIKE=debian
||PRETTY_NAME="Ubuntu 18.04.1 LTS"
ceph.conf is below:
||[client.libvirt]
||log file = /tmp/qemu-guest-$pid.log
||admin socket = /tmp/ceph-asok_changcheng/$cluster-$type.$id.$pid.$cctid.asok
