fstab not respecting _netdev for CIFS mount

WizkidN · #1 25th May 2012, 08:30 PM

Hi,

I'd like to automatically mount a CIFS-network-share on boot. It was my understanding that I could do this with the _netdev option, to make sure it waits until I have a connection. It seems however that this is not being done. I end up with the mount failing on boot.

This is what dmesg shows:

Code:

As you can see, the link does not become ready until 7.08, but it tries to mount at 4.31/4.32.

This is my fstab line

Code:

//192.168.1.112/myshare /home/USER/data        cifs    _netdev,username=USERNAME,password=MYPASSWORD,uid=UID,gid=GID	0 0

Anything I'm doing wrong? I played around with the position of _netdev, but doesn't seem to work >.<

I'm on Fedora 16 - 64bit

Thanks all,

Niels

My /etc/fstab (nas related)

Code:

//ocean/Linux 	 /home/simon/Linux 	cifs credentials=/etc/samba/smb.cred 0	0
//ocean/Music 	 /home/simon/Music 	cifs credentials=/etc/samba/smb.cred 0	0
//ocean/Pictures /home/simon/Pictures 	cifs credentials=/etc/samba/smb.cred 0	0

/etc/samba/smb.cred

Code:

username = MYNAME
  domain = MYDOMAIN
password = MYPASSWORD

Until your post here, i didnt know about the _netdev option.
As you can see, for me this works just as well.

Hope this help.

Hi,

Thanks, but unfortunately, it doesn't work for me. The command itself works, so having a credentials-file can be handy for passwords and such - but I still get the same issue:

I tried this with, and without _netdev, but the result was the same

I don't think it has anything to do with fstab...

Looks to me like it may be NetworkManager (assuming you are using it) messing up again.

The network mount tries to go as soon a systemd thinks the network is ready... but it isn't ready.

Do you have NetworkManager-wait-online.service enabled?

If not, this may help as it is supposed to cause systemd to delay network mounts until it completes (which is listening for NetworkManager to say the network is ready).

Doesn't always work, but still.

WizkidN · #5 25th May 2012, 10:27 PM

I found that the wait-online.service can be enabled with this command:

Code:

systemctl enable NetworkManager-wait-online.service

Rebooted afterwards, but still the same. Thanks though...
