This is because the statistics uses DBUS, and the first ganesha binds the well-know DBUS address, and the rest cannot bind it. Daniel On 6/22/23 10:31, francoise.boudier--- via Support wrote:

Hello,

I meet an issue when collecting the statistics using `ganesha_stats` when several ganesha servers are started on the same node. Each of them use its own NFS port, path, export_id and pseudo.

`ganesha_stats` returns the statistics of the first started ganesha server but fails to collect the statistics of the second one with `Export id not found`.

The rpm in use is nfs-ganesha-utils-4.0-1.el8.x86_64. Is it a know problem and is it fix in a newer version ?

Thanks for your help

See below an example:

- two ganesha servers are running on a single node. # ps -ef | grep ganesha root 2956841 1 0 09:04 ? 00:00:01 ganesha.nfsd -L /tmp/sbbtestgkhLzj8/ganesha/logfile -f /tmp/sbbtestgkhLzj8/ganesha/ganesha.conf -N NIV_EVENT -p /tmp/sbbtestgkhLzj8/ganesha/pidfile root 2957068 1 0 09:04 ? 00:00:00 ganesha.nfsd -L /tmp/sbbtestZoXOzPM/ganesha/logfile -f /tmp/sbbtestZoXOzPM/ganesha/ganesha.conf -N NIV_EVENT -p /tmp/sbbtestZoXOzPM/ganesha/pidfile # df | grep mypath localhost:/mypath.3714 104806400 35679232 69127168 35% /tmp/sbbtestgkhLzj8/mount localhost:/mypath.9019 104806400 35679232 69127168 35% /tmp/sbbtestZoXOzPM/mount
