NFS stopped working

[Takei]

I have used nfs from my computer (server) mounted in osmc for several weeks and it has worked perfectly.

This morning, all of a sudden, it does not work. The share is not mounted in /mnt/Video as it should. But it still works to access the same nfs share from my other computer, and I have not changed anything. fstab on osmc as well as exports on the server checks out, tried sudo mount -a on osmc. Tried rebooting both server and osmc.

The only thing I have changed, is that I connected a new switch yesterday, but after that I watched video from my nfs share on kodi and it worked. And I can still ssh to osmc both from my server and computer. IP is still the same for both server and osmc, the router is the same and I have set static IP there, and verified the IP when I connected with ssh to both server ans osmc.

Please help

@Takei

computer (server)

Which OS are you running?

@Takei

fstab on osmc as well as exports on the server checks out

Can you share the showmount -e <server ip> and also the fstab entries?

[Takei]

Wow quick reply

Server running ubuntu 20.04

osmc@osmc:~$ showmount -e
clnt_create: RPC: Program not registered

get the same from showmount -e on my computer, where I can still access the nfs share.

/etc/fstab

# rootfs is not mounted in fstab as we do it via initramfs. Uncomment for remount (slower boot)
#/dev/vero-nand/root  /    ext4      defaults,noatime    0   0
#
192.168.1.101:/mnt/raid5/Video/           /mnt/Video      nfs    noauto,x-systemd.automount,async  0  0

@Takei

showmount -e

Sorry I mistyped, surley need to be followed by the IP of the server.
showmount -e 192.168.1.101

[Takei]

of course, I should have remembered that myself

The result is the same both from my computer ans osmc

Export list for 192.168.1.101:
/mnt/raid5/Video 192.168.1.103
/mnt/raid5       192.168.1.102

[fzinken]

@Takei

The result is the same both from my computer ans osmc

so 192.168.1.103 is the IP from OSMC box?

[Takei]

Yes

[Takei]

/etc/exports on the server

#
#
/mnt/raid5          192.168.1.102(rw,async,no_subtree_check,fsid=1)
/mnt/raid5/Video    192.168.1.103(rw,async,no_subtree_check,fsid=1)

I tried to disable ufw as well, leaving it disabled for now

Well that got in your way the first time

Add NFS share from Ubuntu

I have setup an Ubuntu 20.04 computer to share with nfs. In /etc/exports there is this line NFSv4 /mnt/raid5/Video/Series 192.168.1.103(rw,sync,no_subtree_check) ufw status give (among otherlines) 2049 ALLOW 192.168.1.103 And on the Vero 4k+ in /etc/fstab 192.168.1.101:/mnt/raid5/Video/Series /mnt/Series nfs noauto,x-systemd.automount 0 0 The ip adresses are correct, use static ip in the router and I have double checked the actual ip’s on each device. But I ca…

Maybe try to force the version.

192.168.1.101:/mnt/raid5/Video/           /mnt/Video      nfs    vers=3,noauto,x-systemd.automount,async  0  0

[Takei]

Yep, I trie to learn from my mistakes. After I got it working I found this library auto update addon in kodi, and during this past night I had the server shut down. If that could have messed up anything…? But I the server have been turned of before and it did not cause any issue.

vers=3 not help… not after mount -a and not after a reboot, still

osmc@osmc:~$ cd /mnt/Video
osmc@osmc:/mnt/Video$ ls
osmc@osmc:/mnt/Video$

@Takei

osmc@osmc:~$ cd /mnt/Video

What is mount saying?
Do you see any errors in the log? Run sudo journalctl -f while you mount from another terminal window.

What is mount saying?

So how about mount output?

[Takei]

Do you mean

osmc@osmc:~$ sudo mount -a
osmc@osmc:~$

[fzinken]

@Takei

Do you mean

No, I mean mount

[Takei]

ran mount -a while journalctl -f ran in another window

[Takei]

Sorry, when there was no parameter I didn’t think it was a command. Here it is

there was nothing new in journalctl -f when I ran mount

@Takei

there was nothing new in journalctl -f when I ran mount

Ok let’s try step by step.

1. Create a test folder mkdir/mnt/test
2. Try to mount to that directory mount -t nfs 192.168.1.101:/mnt/raid5/Video/ /mnt/test
3. If no error check the result ls -lah /mnt/test

[Takei]

well that worked nicely

osmc@osmc:/mnt/Video$ sudo mkdir /mnt/test
osmc@osmc:/mnt/Video$ sudo mount -t nfs 192.168.1.101:/mnt/raid5/Video/ /mnt/test
osmc@osmc:/mnt/Video$ ls -lah /mnt/test

Maybe /etc/fstab is somehow ignored?
