Mount problem

elainelaw · 02-24-2010, 12:09 AM

I have newly installed a RHEL 4 server , this server use NFS mount to connect another RHEL server , but it is strange that the mount will be disconnected in a certain period of time ( between 15 mins and 30 mins ) , I guess the mount is disconnected by the cron job but I can't find it and the old server do not have such problem , can advise what is wrong in my server ? thx

Are you sure it's not the automount that times out?

Code:

ps -ef|grep automount

It that's the case, check /etc/auto.master and/or /etc/init.d/autofs to find out here the timeout is defined.

thx reply ,

I found that only mount to a specific local path have this problem , that mean if I mount the remote path to another local path , then it will NOT disconnect , can advise what is wrong in my system ? thx

I tried to update /etc/sysconfig/autofs to disable #DAEMONOPTIONS="--timeout=60" , but still not work , can advise what is wrong ? thx

Hi,

Check /etc/auto.master. It's the file the aotomounter reads to create mount points and usually the timeout is defined there, like:

Quote:

/misc /etc/auto.misc --timeout 60

If you set it to zero, then timeout is disabled

Regards

You didn't answer about the output of:

Code:

ps -ef|grep automount

to see what is mounted and where it's mounted

So you're not using automount to mount the nfs share.
You should take a look at /etc/fstab to see how it is mounted.
Also looking at the log files could give you some hints why the share gets disconnected.
