Fstab help please

Angelus · May 11, 2021, 11:15am

good day

i have been trying to do this on my own for quite a few days now and i just cant seem to get it right, i dont know what i’m missing.

i have a smb and nfs share on my home local server, i can access it on all my devices except through fstab , i can mount it manually as well using

mount -t auto //192.168../folder /srv/nfs/folder

in my fstab i have this;

//192.168../folder /srv/nfs/music nfs user=angelus,pass=********,_netdev,noauto,x-systemd.automount,x-systemd.mount-timeout=340s,x-system.idle-time=25min 0 0

out put of status systemd-networkd-wait-online.service;

[angelus@Angelus ~]$ systemctl status systemd-networkd-wait-online.service

soooooooo i dont know lol please if anyone can advise perhaps where iam going wrong or what is missing or what i can check on

That isn’t the correct format for an nfs mount. It looks like you have combined a mix of things from smb and nfs and they are different.

Here is what my nfs mounts look like:

192.168.2.154/music /srv/nfs/music nfs x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

Also, /etc/exports is for an nfs server. You shouldn’t need anything special in that for an nfs client.

Angelus · May 11, 2021, 11:33am

ok i made mine look the same;

//192.168.2.154/music /srv/nfs/music nfs x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

now it gives me this error

failed to open directory “music” error opening directory ‘/srv/nfs/music’: no such device

dalto · May 11, 2021, 11:53am

What gives you that error?

Did you umount your manual mount first?

After making sure it is unmounted you can test the mount with sudo mount /srv/nfs/music

Also, I copied and pasted your location but is that a typo? Should it be svr?

Angelus · May 11, 2021, 12:07pm

i got that error after i changed the line in fstab and then saved fstab and restarted and then browed to /srv/nfs/music and then it told me that error. but no i did not umount before the restart

yes i checked now “srv” is correct, if i go; file system > srv > nfs > music

if i do the test this happens

[angelus@Angelus ~]$ sudo mount /srv/nfs/music
mount.nfs: remote share not in ‘host:dir’ format

dalto · May 11, 2021, 12:08pm

Can we see the contents of /etc/fstab

Angelus · May 11, 2021, 12:29pm

/etc/fstab: static file system information.

Use ‘blkid’ to print the universally unique identifier for a device; this may
be used with UUID= as a more robust way to name devices that works even if
disks are added and removed. See fstab(5).

UUID=6ff6ad6d-f310-4764-873e-89b7884e38ec / ext4 defaults,noatime 0 1
UUID=9d0940fc-7903-40c0-aab0-7ad78aca66bd /mnt/ ext4 rw,auto,user,suid,exec 0 0
//192.168.2.154/music /srv/nfs/music nfs x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

dalto · May 11, 2021, 12:36pm

You added // at the beginning. That isn’t part of an nfs mount.

You should be able to copy and paste the line I gave you exactly without any changes.

Angelus · May 11, 2021, 4:17pm

ok copied it as you had it now and restarted but when i browse to /srv/nfs/music it gives the error

failed to open directory “music” error opening directory ‘/srv/nfs/music’: no such device

updated fstab

#<file system>             <mount point>  <type>  <options>  <dump>  <pass>
UUID=6ff6ad6d-f310-4764-873e-89b7884e38ec /              ext4    defaults,noatime 0 1
UUID=9d0940fc-7903-40c0-aab0-7ad78aca66bd /mnt/ ext4 rw,auto,user,suid,exec 0 0
192.168.2.154/music /srv/nfs/music nfs x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

dont know if this helps

What error do you get if you type sudo mount /srv/nfs/music

Angelus · May 11, 2021, 4:50pm

[angelus@Angelus ~]$ sudo mount /srv/nfs/music
[sudo] password for angelus:
mount.nfs: remote share not in ‘host:dir’ format
[angelus@Angelus ~]$

dalto · May 11, 2021, 4:53pm

That is my fault.

I dropped the colon.

Try this:

192.168.2.154:/music /srv/nfs/music nfs x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

Angelus · May 11, 2021, 5:04pm

ok i changed it to that and rebooted but it didnt mount on restart, so i ran;

sudo mount /srv/nfs/music
[sudo] password for angelus:
mount.nfs: mounting 192.168.2.154:/music failed, reason given by server: No such file or directory
[angelus@Angelus ~]$

there was a command i stumbled on that will display available shares even if not mounted um,

dalto · May 11, 2021, 5:07pm

What is the server?

Is it possible that /music isn’t what it is called on nfs?

For example, I have a Synology and when you connect via smb it is //server/share but when you connect via nfs it is server:/volume/share

EDIT: Also, did you give your client IP permissions to connect?

Angelus · May 11, 2021, 5:32pm

yeah iam thinking about that now … my server is running omv with smb/cifs and nfs share. i’m digging in omv now to see if i can spot anything on the real folder path …

there is a section for shared folders
and under “shared folders in use” it displays

and under “shared folders” it displays

where Music/ is labeled as relative path

under nfs shares it displays

dalto · May 11, 2021, 5:53pm

Is 192.168.2.150 the IP of the client machine you are trying to connect from?

Angelus · May 11, 2021, 5:54pm

correct yes

dalto · May 11, 2021, 5:58pm

For OMV it looks like you can look in /etc/exports on the OMV server to get the share name.

It looks like by default it is /export/sharename. Keep in mind it is case sensitive.

Angelus · May 11, 2021, 6:02pm

ok so then it would be

192.168.2.154:/export/Music /srv/nfs/music nfs x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

dalto · May 11, 2021, 6:11pm

Try it!
