This is reposted here to hopefully attract som answers. Original post: https://superuser.com/questions/1001470/files-directories-created-on-nfs-mount-with-no-permissions

I have a set up with a client running ubuntu 15.10 and a NFS server (Synology NAS, with DSM 5.2). I've succesfully mounted the share I need using the following line in fstab:

diskstation:/volume1/share /mnt/DiskStation/share nfs rw 0 0

(It doesn't automount - but thats another question :))

My nas is setup with rw privilege and permission to access mounted subfoldes - i use no_root_squash since im not accessing the share as root.

My problem is when I create a file or directory it is created with d--------- and is obviously inaccessible without running af chmod command first. I would like the files to be created with read and write rights for user and group and read for guests.

I've set my umask to "002" - but it doesn's seem to change a thing.

What can I try/do?

  • That mount sttmt seems wrong to me. see help.ubuntu.com/community/SettingUpNFSHowTo – Rinzwind Nov 17 '15 at 12:30
  • What UID (id -u) are you using on the client? What UID does that get mapped to at the server? – waltinator Nov 17 '15 at 17:25
  • @Rinzwind - i've tried different options, same result. From what I can understand from the NFS man page, and the link you shared, the mount sttmt is with default nfs settings. – Hoof Nov 17 '15 at 18:44
  • @waltinator - I have a user x on both systems. On the client x has uid 1000 and on the server has uid 1026. – Hoof Nov 17 '15 at 18:47
  • @waltinator - i kinda get, where this is heading. I'm not familiar at all with the concepts and how they play a role in nfs, but i'm guessing they should match in some way... Can I change the uid somehow? And should it be done on the server or the client? – Hoof Nov 17 '15 at 18:50

By changing my client's user's uid to match the uid of the user on the server, everything worked perfectly. Follow this guide to change uid of a user: How can I change my own user ID?
