I believe this is a Ganesha bug, as discussed on the Ganesha list.
Ah, thanks. Do you maybe have a link or subject so I can chime in?

Hi,
I have a CephFS filesystem which is re-exported through NFS Ganesha (v2.3.0)
with Ceph 10.2.2
The export works fine, but when calling a chgrp on a file the UID is set to
root.
Example list of commands:
$ chown www-data:www-data myfile
That works, file is now owned by www-data/www-data
$ chgrp nogroup myfile
Does the nogroup group have GID -1 by any chance? There is a bug in
the userspace client where it doesn't handle negative gid/uids
properly at all, which Greg is working on at the moment
(http://tracker.ceph.com/issues/16367)
No, it doesn't. nogroup is just an example here. This happens with any group.
The UID is always set back to 0.

That files, the UID is now set to 0 (root) and the group hasn't changed.
I tracked this down to being a Ganesha problem in combination with CephFS.
Running these commands on either a kernel mounted CephFS or via FUSE I don't
see this problem.
The Ganesha configuration:
NFSv4
{
IdmapConf = /etc/idmapd.conf;
}
EXPORT
{
Export_ID = 1;
Path = "/";
Pseudo = "/";
Access_Type = RW;
Protocols = "4";
Squash = no_root_squash;
Transports = TCP;
SecType = sys;
FSAL {
Name = CEPH;
}
}
Has anybody seen this before?
Wido
