[Gluster-users] Permission denied closing file when accessing GlusterFS via NFS

[David Cunningham]

Hello,

We have a GlusterFS node which also uses the FUSE client to mount the
filesystem. The same GlusterFS node server also runs an NFS server which
exports the FUSE client mount, and another machine NFS mounts it.

When the NFS client writes data to the mounted filesystem we are seeing
"Permission denied" errors like this:

cp: closing
`/var/lib/gfs/company/david/1075/Copyrec/1628448189883606-203-17184805327-out-08-08-21-14~43~10-203.mp3':
Permission denied

The file mentioned in the error is actually created on the GlusterFS
filesystem, but has zero size, so the problem is not a normal Linux
filesystem permission one.

In the brick log nodirectwritedata-gluster-gvol0.log on the GlusterFS node
we see an error as follows. Would anyone have a suggestion on what the
problem might be? Thank you in advance!
