Explanation for PRVE-10183: File system path "/var" is mounted with 'nosuid' option on node "xxx"

Hi everybody !

When trying to upgrade from Oracle Grid Infrastructure 12.1 to Oracle Grid Infrastructure 12.2 (on RHEL 7.4 ), I ran CVU :

./runcluvfy.sh stage -pre crsinst -upgrade -rolling \

-src_crshome <source_home> \

-dest_crshome <dest_home> \

-dest_version 12.2.0.1.0 -fixup -verbose

 

And got the following error :

PRVE-10183: File system path "/var" is mounted with 'nosuid' option on node "xxx".

 

I did what had to be done to get rid of this error, but I need to have a clear justification for such recommandation : Why can't we have /var mounted with 'nosuid' option ?

I did not find anything on official documentation nor Oracle support, for the moment.
