Description

We currently don't have a way to tell what the client ID of a particular mount is, in situations where there are multiple mounts on the same machine.

There are a couple of potential approaches -- maybe a new ioctl that could be used with an O_PATH fd, or it may be possible to add a new fsinfo() request field (if and when that is merged).

Basically we just need an ioctl or new vxattr that dumps out a clientid for the mount (preferably in the format that the directories under /sys/kernel/debug/ceph are named).

A new vxattr may be the best way to do this, actually. Easier for scripts to get to, for instance.

As disscussed will switch to vxattr approach:


[root@lxbceph1 kcephfs]# getfattr -n ceph.cluster_fsid file
# file: file
ceph.cluster_fsid="6ff21dc9-36b0-45a9-bec2-75aeaf0414cf" 

[root@lxbceph1 kcephfs]# getfattr -n ceph.client_id file
# file: file
ceph.client_id="client4358"
