I'm trying to share a NFS mount among multiple users. I can't get it to work, because I always get access denied. I can mount the shares, but I can't see the files.
The export is made through Heartbeat+Pacemaker. I don't think that makes the difference, but here's the export config:
primitive exports_nfs_proys ocf:heartbeat:exportfs \
params rmtab_backup="none" directory="/export/proyectos" clientspec="172.16.54.0/24" options="rw,async,no_subtree_check,insecure,root_squash" fsid="2" \
op monitor interval="30s" \
op start interval="0" timeout="240s"
So I mount the NFS share:
jorge.suarez@decp1304:~$ sudo mount -t nfs4 172.16.54.56:/proyectos/innovacion /mnt
jorge.suarez@decp1304:~$ cd /mnt
bash: cd: /mnt: Permission denied
On the client:
$ stat /mnt
File: «/mnt»

So, I'm doing something wrong, but all seems OK here. The UID/GID are matching on client and server.
If I set the directory permissions to 777 I can access, read and write the directory, but I want to restrict this just to some users so that's not an accepted solution.
