[SOLVED] Way to automount nfs share as needed?

jmgibson1981 · 04-04-2019, 05:21 PM

I have been trying to get autofs to work for awhile now. My problem is that it works for the first day or so. After that I can't get it back. When trying to touch my autofs mount it just says permission denied. Trying to ls and it says no such file or directory. Debian stable. I've had the exact same problem on ubuntu.

Hi jmgibson1981,

Could you post the entry from fstab file please ?

Thanks,

There isn't an fstab entry associated with autofs unless the OP is using systemd automount but then it would not be autofs...

Post your auto.master file and if you are using the manual method the autofs configuration file associated with the nfs mount.

Also is this a virtual or real system and if you normally shutdown or does the system go to sleep?

You can also turn on autofs logging by changing the logging setting in /etc/autofs.conf to 'verbose' or 'debug'. The default is 'none', so when there is a problem, it just silently fails. I've found verbose usually provides enough information.

After changing the setting, you need to restart autofs.

Once logging is enabled, autofs will send messages to syslog about what it's doing and any errors encountered. I think on Debian, the messages are output to /var/log/syslog.

Code:

+dir:/etc/auto.master.d
+auto.master

/megalith /etc/auto.megalith --timeout=30

Stripped out the comments in the file.

Code:

pool -fstype=nfs,rw,soft,intr,rsize=8192,wsize=8192 megalith.mylan.home:/snapraid/pool

I just added the -fstype last night and things seem to working today as well, that may have been it. Didn't have that part before. But these are based on the Arch wiki.

Not having -fstype is most likely the reason autofs was not working.

In that case I will mark as solved and if it pops again I will post. Thank you for views + hopeful confirmation.

Indeed ... read too quickly and also from my own context, where I use fstab for all mounting. Thanks, michaelk.

Cheers, all.
