Re: [mh] NFS and permissions

Hi Giles,

Thanks for the idea. Unfortunately, it didn't make a difference.

After the volume is mounted, the permissions all disappear from the perspective of the 'pi' user.  However, if I were to do a 'su' to root and then a ls -l /mnt, I would see the syn folder has rwx for owner,group,everyone.

I'm not sure if this is related, but some early versions of PI had problems with NFS version 4 on Synology NAS, when this happens, I force it to use version 3 by for example having an fstab something like this

192.168.100.35:/volume1/pishare /mnt/pishare nfs nouser,atime,auto,rw,dev,exec,suid,nfsvers=3 0 0

Regards

Giles

Hello All,

This isn't a MH question/issue per se, but it does involve a raspberry PI that I might would like to make my MH machine.

Short story:
I have a Synology NAS that has a NFS volume/path exported
I have to RPIs that can mount the NFS volume and read/write with no issues
I have a brand new RPI 4 and an older Debian (stretch) install that mounts the NFS volume, but gets a permissions denied when trying to simple ls the contents of the volume.

Logged on as pi,

sudo mkdir /mnt/syn
sudo mount <NAS>:/volume1/nfs /mnt/syn
ls -l /mnt


d--------- 1 root root 268 Oct 13 14:24 syn

is the result I get after mounting, if I were to unmount the volume (and these are the same values before mouinting), I get the following from the ls -l command:

drwxr-xr-x 2 root root 4096 Oct 13 14:02 syn

As I see it, the chmod permission are changing when mounting the NFS volume. The strangest part to me is that it works on 2 other RPIs.

I hope someone has some ideas I cnatry.

Tim
