[SOLVED] Can no longer mount QNAP folders on my Ubuntu 20.04 Desktop

Post by DigitalMan »

My QNAP TS-453D is hardwired to my router (via a switch) and my Ubtuntu 20.04 Desktop computer is hardwired to the same router.

I have no desire to ever connect to my QNAP from outside of my local network.

I have had nfs-common installed on my Ubuntu, and historically, the settings on my QNAP granted me "Access right" to the folder, read/ write permission, and "Squash no users."

Again, historically, I would simply go to terminal and:

mount -t nfs xxx.xxx.x.xxx:/FOLDER_ON_QNAP /home/username/FOLDER_ON_QNAP

And the folder would mount on my Ubuntu without any difficulty.

As of the upgrade to QTS 4.5.5.715 I suddenly cannot mount folders from my QNAP to my Desktop in this manner. Instead, I get this error:

mount.nfs: access denied by server while mounting xxx.xxx.x.xxx:/FOLDER_ON_QNAP

Also, I notice that the NFS host access options have changed.

Now, under "Access right" there is an option "sync" with a drop down "wdelay" or "no wdelay" and an option to "secure"

Also, there is now a "Security" box next to the allowed IP which says, "sys,"

What am I doing wrong? How can I mount my QNAP to my Ubuntu 20.04 once again?

Many thanks.

Solved.

Somehow, when QTS upgraded firmware to 4.5.5.715 it wreaked havoc on my local network.

First, I unplugged the QNAP from the switch.
Then, I unplugged the switch from the router.
Then, I did a factory reset on the router and reconfigured it.
Then, I plugged in the switch, did a factor reset, and reconfigured it.
Then, I plugged in the QNAP once again.

Finally, I can mount QNAP folders on my Ubuntu via NFS and all is as it should be.

I'm not sure why upgrading firmware on the QNAP should cause such a problem, but at least it's solved now.
