[Gluster-users] nfs acces denied

Mon Mar 31 15:26:25 UTC 2014

Well, with 'client' i do actually mean the server itself.
i've tried forcing linux and windows to nfs V3 and tcp, and on windows i played around with the uid and gid, but the result is always the same

Well, saying your client-side is "linux" does not help much. Distro, flavor, etc helps a lot, but I'll take a wild guess here.

First, force your NFS mount (client) to use nfs version 3.

The same for Microsoft. (It is fair to say I have no idea if the MS client supports v4 or not).

Additionally, check that firewalls are disabled on both sides, just for testing. The same goes for SElinux.

Windows and ACL, and user mapping is something that might be in your way too. There is a Technet document that describes how to handle this mapping if I am not wrong.

Just for testing, mount your nfs share you your own server, using localhost:/nfs_share and see how it goes.

It is a good start.

Hello all,

I’ve already tried to post this, but i’m unsure it arrived to the mailing list.

I have some issues regarding my nfs mounts. My setup is as follows:
Rhel 6.4, gluster 3.4.2-1 running on a vm (4 cores, 8GB ram) attached to a san. I have one disk on which are all the bricks (formatted ext4 in 64 bit mode) of 25TB.
On the gluster side of things, everything works without issues. The trouble starts when I mount a volume as an nfs mount.
Lots of volumes work without issues, but others behave strangely. The volumes that act weird generally contain many files (can be accidental?).
The volumes in question mount without issues, but when I try to go into any subdirectory sometimes it works, sometimes I get errors.

On windows with nfs client: access denied

The weirdest thing is it changes from time to time which files and directories work and which don’t
Any ideas?

Thanks!
