I finally found something from the logs,

Code

That matches the authentication error from the GUI, that I missed earlier.

Code

6/9/2021, 08:42:01
CRON[26040]: pam_unix(cron:session): session opened for user root(uid=0) by (uid=0)

I believe this one is preventing me to mount the shared nfs folder.

What changes should I apply to fix this one?

Hello,

I just run the script from github as suggest, to install OMV on a raspberry pi 4. The default user pi was replaced with another one.

After I enabled NFS share, then I cannot mount the remote folder on my linux machine.

[raspberry pi]

----------------

Code

$ showmount -e
Export list for k8sn01b:
/export           192.168.0.0/24
/export/PcyBackup 192.168.0.0/24



$ cat /etc/exports
# This file is auto-generated by openmediavault (https://www.openmediavault.org)
# WARNING: Do not edit this file, your changes will get lost.


# /etc/exports: the access control list for filesystems which may be exporte

/export/PcyBackup 192.168.0.0/24(fsid=1,rw,sync,insecure,no_root_squash,no_subtree_check)


# NFSv4 - pseudo filesystem root

# /export 192.168.0.0/24(ro,fsid=0,root_squash,subtree_check,hide)
/export 192.168.0.0/24(rw,fsid=0,root_squash,insecure,no_subtree_check,nohide,sync)

Then, on my machine

Code

$ sudo showmount -e 192.168.0.20
Export list for 192.168.0.20:
/export           192.168.0.0/24
/export/PcyBackup 192.168.0.0/24


$ sudo mount -vvv -t nfs 192.168.0.20:/export/PcyBackup /mnt/MyBackup/
mount.nfs: timeout set for Sat Sep  4 09:12:32 2021

I also tried,

Code

$ sudo mount 192.168.0.20:/PcyBackup /mnt/MyBackup/
$ sudo mount 192.168.0.20:/ /mnt/MyBackup/

but same issue.

There is nothing in the logs, the folder is empty.

Code

$ ls -la /var/log/openmediavault/
total 0
drwxr-xr-x  2 root root   40 Dec 14  2020 .
drwxr-xr-x 14 root root 1520 Sep  4 00:17 ..

With the GUI in Diagnostic > System Logs, there is nothing at all.

The workaround I found to access my shared folder is to modify the pseudo filesystem root from the export file. This way, I can open directly my shared folder after I click the option to "browse network".

Anyone can help to fix the mount option, so I can set the export file into its default configuration? Thank you.
