Softlink disappears

We have ES80 and GS140 running Tru64 V5.1B-3 (patch kit 5) both nodes are single node cluster. ES80 exports a file system to GS140.
I have made a softlink on GS140 to this NFS share. Some time this softlink file goes missing and I have to recreate the link with NFS share.

Why does this happen?
Will changing the NFS protocol from UDP to TCP make any change?

What, exactly, did you do, and where?

What does this mean?

Actual commands? Actual output?

Re: Softlink disappears

ON ES80 - Export file system /abc/test to GS140.
On GS140 -
mount -t nfs es80clu:/abc/test/test1 /test1
cd /abc/test
ln -s /test1 file1
ls -l
lrwxrwxrwx 1 user grp 10 Aug 18 07:11 file1 -> /test1

The softlink file file1 disappears from /abc/test on GS140. How it can happen?

Someone or some script would have to remove it.
Does the directory /abc/test have much activity? If not, then the modification date of test could be the time it was removed.

You can use the Audit subsystem to track down what is happening. See the documentation on the Audit subsystem in the Security Administration manual.

Re: Softlink disappears

As the softlink was disappearing 2-3 times a week plus when netwok was busy users were not seeing the link intermittently. So what I have done I made local directory and copy files from the NFS folder and softlink points to this new local folder.

I do not have any issue since then.
