NFS Config for connection Timeout

[kd4pba]

I am confused on this one, maybe someone can answer this.

I have several boxes running Linux , RedHat 7.3 and 8.0.
I have NFS shares on each of them.

Here is an example of my problem.
If Box (a) is sharing mount /home
and Box (b) has this share mounted
and Box (a) crashes I have issues shutting down Box (b), it will hang on trying to Unmount the NFS mount. And when I say hang, its forever, I let it sit overnight once and it never got past that point. The problem is these are ummounted before the local file systems. So, If I reset, I end up in FSCK-land, I dont like this place ;-)

Now, in fstab I believe I have it setup for now as just
Example
box(a):/home nfs
I am not sure what additional param's to put in for timeout.

Also I am exporting this as no_root_squash, I know I should not but this is for testing.

Is there a way to get a timeout so my system does not hang when trying to umount something that it cannot connect to?

thanks

Well, you'd have to use the options hard,intr but it's not recommended.

Have you tried using automounter? It has a timeout setting.
