Network drive mystery

Post by papaworx »

I am running two Linux Mint 20.1 hosts one on ethernet, one on broadband wifi, and both should use a Synology NAS on ethernet as network drive.
In both hosts I have the same fstab line:

Code: Select all

192.168.x.y:/volume1/ChainPro /mnt/ChainPro nfs rsize=8192,wsize=8192,timeo=14,intr
The ethernet host mounts the NAS partition without problems.
The wifi host balks:

Code: Select all

$ sudo mount -t nfs -vvvv 192.168.x.y:/volume1/ChainPro
mount.nfs: timeout set for Tue Apr 27 17:08:17 2021
mount.nfs: trying text-based options 'rsize=8192,wsize=8192,timeo=14,intr,vers=4.2,addr=192.168.x.y,clientaddr=192.168.x.z'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying text-based options 'rsize=8192,wsize=8192,timeo=14,intr,vers=4.1,addr=192.168.x.y,clientaddr=192.168.x.z'
mount.nfs: mount(2): Device or resource busy
But the wifi host can ping the NAS without problems.
What is going on? (x, y, and z mask the actual numbers here)

The mystery is your lack of understanding that wifi != ethernet. There is no evidence that your wifi can support rsize=8192,wsize=8192, so dropping all of the fancy mount options is the first place to start, and just use defaults until you nut out what options are actually supported and are actually necessarily needed.

As already mentioned; stick with defaults to make sure things actually connect.

After that, masking RFC1918 private addresses is kind of shooting yourself in the foot as well. There's no reason whatsoever to do that.
