NFS Issues (?)

[mcraidy]

I've been unable to get NFS shares exported on my Unraid set up for some time now and was wondering if anyone has any tips!

 

SMB seems to work fine however when I set up NFS shares I don't seem to see the exports on the Unraid system or remote servers I'm trying to connect to the export.

 

Share shows NFS config

and

and NFS enabled under settings

 

On the Unraid server /etc/exports is populated

# See exports(5) for a description.
# This file contains a list of all directories exported to other computers.
# It is used by rpc.nfsd and rpc.mountd.

"/mnt/user/backup" -fsid=102,async,no_subtree_check 172.24.15.51(sec=sys,rw),subtree_check
"/mnt/user/frigate" -fsid=103,async,no_subtree_check *(rw,sec=sys,insecure,anongid=100,anonuid=99,all_squash)
"/mnt/user/isos" -fsid=100,async,no_subtree_check *(rw,sec=sys,insecure,anongid=100,anonuid=99,all_squash)
"/mnt/user/proxmox-backups" -fsid=101,async,no_subtree_check *(rw,sec=sys,insecure,anongid=100,anonuid=99,all_squash)

 

BUT showmount -e localhost returns nothing

root@storage:~# showmount -e localhost
Export list for localhost:

 

Anyone have any golden tips?

 

FYI the nfsd module is installed and seen with lsmod too.

Does anyone have any suggestions?!

 

NFS still isn't working - have upgraded now to 6.12.6 hoping it'd work, but still nothing!

Post a diagnostics.

[mcraidy]

Have just enabled local syslog as I was sending all remotely.

 

Diagnostics dump attached.

 

After disabling NFS a tail of /var/log/*log when enabling has provided

Although I've tried many times to get NFS going - the latest attempt was with the "photos" share.

 

Any further help would be fantastic

Looking around at /etc/rc.d/rc.nfs I found some of the stuff in /proc which also seems to indicate that nothing is exported:

 

root@storage:~# cat /proc/fs/nfsd/exports
# Version 1.1
# Path Client(Flags) # IPs

FIXED

 

As seen in the logs:

I ran exportfs -r manually and finally saw an error:

root@storage:~# /usr/sbin/exportfs -r
exportfs: /etc/exports:2: syntax error: bad option list

 

I disabled the 2nd NFS share as seen in `/etc/exports`:

# See exports(5) for a description.
# This file contains a list of all directories exported to other computers.
# It is used by rpc.nfsd and rpc.mountd.

"/mnt/user/backup" -fsid=102,async,no_subtree_check 172.24.15.51(sec=sys,rw),subtree_check
"/mnt/user/frigate" -fsid=103,async,no_subtree_check *(rw,sec=sys,insecure,anongid=100,anonuid=99,all_squash)
"/mnt/user/photos" -fsid=104,async,no_subtree_check *(rw,sec=sys,insecure,anongid=100,anonuid=99,all_squash)

 

And NFS now seems to start (running showmount -e on the server returns the exports).

 

FYI the bad config for the backup share was:

 

I've now fixed and all working.

 

For the devs - it'd be great if there was some sort of validation of the config and/ or some indication that NFS isn't actually running.
