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

Wed Aug 11 02:21:27 UTC 2021

And on the NFS server the user can write into the FUSE, right?

Thanks very much for your replies. SELinux is disabled on the NFS server (and the client too), and both have the same UID and GID for the user who owns the files.
On the NFS mount we had options "rw,noatime,hard,bg,intr,vers=4". I added "async" which did not solve the problem, and the NFS client mount gave an error when trying to use "no_root_squash" or "no_subtree_check". Gilberto, is there a specific reason why you suggested those options?
Thanks again.

Hey David,
can you give the volume info ?
Also, I assume SELINUX is in permissive/disabled state.
What about the uod of the user on the nfs client and the nfs server ? Is it the same ?

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!
