I have a Synology NAS and an Ubuntu 18.04 client and I'm trying to mount the drive via NFS. It mounts well, but I can only see the folders as read-only in Nautilus. Everything in /etc/exports was specified correctly, I'm only sharing one folder to one IP and rw is specified:
admin@DS211:~$ sudo cat /etc/exports /volume1/pub 192.168.0.205(rw,async,no_wdelay,all_squash,insecure_locks,sec=sys,anonuid=1024,anongid=100)
...then some research suggested that it might have something to do with the usernames and the UIDs being different, so I created a new user with the same UID as the admin user on the NAS to test this, and found I could now create folders on the remote drive -- but only through the terminal and with both my new user and the standard user. I only have read-only access through Nautilus, no matter with which user I open Nautilus. I also tried it through a line in
/etc/fstab and get the same result.
:~$ grep pub /etc/fstab 192.168.0.100:/volume1/pub /media/NAS_PUB nfs auto,nofail,noatime,nolock,intr,rw,tcp,actimeo=1800 0 0
