Simply cannot get Glances in docker to monitor nfs mount

[DeltaTangoLima]

Has anyone discovered any particular trick to getting Glances to see nfs mounts inside a docker container, please?

Initially I tried mounting the nfs share on the host (using autofs) and using a bind mount in my compose file. Then I tried using an external docker volume to mount the nfs share directly inside the container, again mounting it via the compose file.

In both cases, I'm mounting on /mnt/nfsshare inside the container, but Glances doesn't see it. It sees a USB SSD drive from the host that's mounted on /mnt/usbdrive just fine. If I run df -h inside the container, it sees the nfs share mounted where expected, with fs type nfs, but no combination of config options is making Glances show it.

Relevant glances.conf snip:

[fs]
allow=nfs
show=/mnt/.*

Am I missing a magical incantation somewhere?

Thanks in advance.

EDIT: I should add that I've used the -d flag to get extra debug output, but there's nothing relevant being logged.

Hi @DeltaTangoLima

Try this:

[fs]
allow=nfs,nfs4
show=/mnt/.*

Or:

[fs]
allow=nfs,nfs4

Hey @nicolargo - thanks for replying. Unfortunately, the suggestion above hasn't helped. I can confirm the container can absolutely see the mounted nfs share, but the Glances container cannot (or will not).

I've tried with two different nfs servers (NASes) and no dice.

EDIT: I've even tried with my brand new TrueNAS, using nfs4 - same problem.
