Hi All,

A bit of an oddball one - well it's me you're probably used to that by
now. After replacing the failed HDD in my Synology DS212j I decided to
split my files among Graphics, Video and General. That has worked up to
a point. The configuration is:

Cerce - Main PC - Fixed IP 192.168.1.2.
Zeus - NAS - Fixed IP 192.168.1.3 with three Shared Folders:

HERA: General Files
DIANA: Graphics Files
PERSEPHONE: Video Files

First of all I was able to access them by browsing the network, and
entering the UID and PWD to access them. That's how I transferred all
the files to them. However long term that's a pain in the bum so I want
them to auto mount on boot. Initially none of them would mount at all using

sudo mount -t nfs 192.168.1.3:/volume1/HERA /media/julian/HERA

for example, so I had a poke around and found Synology's guide for
getting NFS Shared Folders to work. All three now have NFS Permissions
to allow 192.168.1.2 Read/Write access. I tried first of all in a
terminal before adding them to the fstab - and potentially rendering the
system unbootable if it hung trying to load them. This is where it gets
odd. Diana and Persephone mount perfectly well with the above sudo
command and can be browsed as normal. Hera however mounts with no error
but refuses any attempt to browse it. There is no error message, simply
nothing happens.

Then I added Diana and Persephone to the fstab and rebooted. Both
function perfectly, however as Hera has my main files on I need that to
mount properly too. Any ideas please?

Kind regards,

Julian

Permissions issue?

What does dmesg say after mounting the HERA share, and do 'mount' and
'df -klh' show the expected outputs?
To be honest I don't know what the expected outputs would be however I assume all three should show up if mounted, as they are at the moment:

julian@Cerce ~ $ mount

[extraneous info sipped]
192.168.1.3:/volume1/PERSEPHONE on /media/julian/PERSEPHONE type nfs (rw,relatime,vers=3,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=70,retrans=2,sec=sys,mountaddr=192.168.1.3,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.1.3) 192.168.1.3:/volume1/DIANA on /media/julian/DIANA type nfs (rw,relatime,vers=3,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=70,retrans=2,sec=sys,mountaddr=192.168.1.3,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.1.3) 192.168.1.3:/volume1/HERA on /media/julian/HERA type nfs (rw,relatime,vers=3,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.1.3,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.1.3)

This is the only difference I can see between the three: rsize=131072,wsize=131072, and timeo=600. Are these significant?

julian@Cerce ~ $ df -klh

tmpfs           799M   52K  799M   1% /run/user/1000

This is a bit odd as all three are currently mounted - Diana and Persephone at boot - albeit Hera is inaccessible via the mounted icon on the desktop.

Can you 'sudo ls -alh
/media/julian/HERA' and see your files?
Yes that works.

Kind Regards,

Julian
