group id's and failover

[Dan Copeland]

Admins,

Do the group id's for file ownership need to be identical on all configured nodes for successfull failover or does the group name just need to be the same?

tia,

Dan

Hi,

It seems to me that it is most important the group id's are the same as used on the other node. Just a matter of correct permissions.

Both UID's to logins mapping AND GID's to group mappings should be identical. I say should rather than must because it depends upon the specific application and file permissions. The safe way is to make sure that the passwd and group files are identical on all nodes or even better to use NIS/NIS+ to absolutely ensure that they do.

Hi


For me you should go for identical.

The numbers are used to get the group id.

Hi Dan,

The numeric id is what's used for permissions on files and directories, not the group name. The group name and numeric id should be the same on each system in the cluster. Otherwise members of a group may not have the permissions they need to successfully run the applications.
