autofs

[Aaron_11]

I am having problems automounting nfs volumes using autofs. Most of the time things work fine, but occassionally, while changing directories to a mounted fs, the cd command hangs. This only happens occassionally (perhaps due to network fluctuation?). At any rate, The fs that is usually the culprit is a SunOS. Generally when the problem occurrs, the whole server tends to lock up shortly thereafter. Is this common behavior, or am I missing a critical patch or something. Any advice would be greatly appreciated. Thanks in advance.

First, are you sure you are using autofs and not the older automount?
Check /etc/rc.config.d/nfsconf to see if the variable AUTOFS=1 (new autofs) If it is missing or 0, you are using the old automount.

Are you using direct or indirect mapping?

Are you certain that DNS is working correctly?

Try turning on logging and tracing by setting AUTOMOUNTD_OPTIONS="-v -T" in the nfsconf file.

HTH,

Thanks for the response,

I am running autofs (AUTOFS=1 in nfsconf). The mapping I believe is indirect (Several boxes export and autofs takes the requests and mounts them under /net). As to whether DNS is working correctly I'm not sure how to check. I can't see any obvious problems. I have turned on tracing and will see if this sheds any new light on the subject. Thanks

Sounds like NFS performance issue.
I'm attaching a document on how to perform NFS diagnostics.

hope it helps
