nfslock not running at startup

Andrew Kaplan — Tue, 25 May 2004 09:59:48 GMT

We have a group of Red Hat 7.3 servers running a clustering application. One peculiarity that occurs is when a system is brought down and subsequently rebooted, the nfslock daemon does not automatically activate on startup. I am
forced to manually start the daemon. Has anyone had this problem occur on their systems, and if so what was the fix? Thanks.

Hi,

Please include some more info.

chkconfig --list

You need for nsf services, poprtmap, nfs and nfslock.

This machine is a nfs export server? or a nfs client?.

Hi there --

I've included a printout of the chkconfig command for your perusal. Thanks again for your reply.

Hi Andrew,

You don't answerme when I ask about if your machine is a Server or a Client.

I'm supossing it is a client.

Do a chkconfig portmap on

and Try, If does'n work, try this: Disable the nfslock and try to mount the nfs folder anyway.

I'm stuck with your problem because i'm guessing many things.

By other hand, the bests practices for your needing, is enable and configure the autofs, so your linux will mount and dismount the folder when is necesary.

Alvaro.

It's my understanding that for most versions of NFS on Linux, the NFS lock will not survive a failover to another machine.

Some clusters that support it have special code to handle that case.

Andrew, one possibility I can think of is if you have clustered you /var/lib/nfs directory as you're supposed to.

When the system comes up, is the /var/lib/nfs directory actually available at the time, or is it still on the other node?

I am pressuming here that the cluster is the root cause of the problem and that you have a shared filesystem using drbd or something. Can you supply more information about how you've built the cluster?
