SAM erased contents of netgroup file

[Andrew Kaplan]

Hi there --

We are running 11i v1 on a ServiceGuard cluster, and ran into the following incident. Two nodes were to be added to one of the groups listed in the /etc/netgroup file. The first step was to modify the /etc/hosts file with the appropriate information pertaining to the nodes.

The SAM utility was then used to access the section "Networked File Systems/NIS Groups". The two nodes were added using SAM, and when prompted, the new NIS map was pushed. However, upon checking the results, it was discovered that a blank map was pushed instead of populated one.

The end result was the administrator manually adding the two nodes a restored version of the netgroup file, and then running the ypmake command.

Has anyone seen this, and know what would have caused it? Thanks.

Shalom,

Restore the missing files and check for patches dealing with this issue.

At the very least, bring the system current with a recent bi-annual patch set.

This can be caused by a file system going 100% during a push.

Hi there --

One other theory came up: If one administrator makes changes via SAM, and another subsequently makes changes via a command prompt, would the combination of the two cause the condition that was described in the original e-mail?
