exportfs -v and sync option

Dear Friends,

I am using Linux system where one nfs share has been configured with rw,sync options. But when I use to check with exportfs -v command it does not show me the sync option I enabled in /etc/exports

My doubt is whether I need to use any other command or other options to see the sync option I enabled.

Thank you.

What does /etc/mtab show?

Dear Jim,

I am checking on nfs server end not on nfs client end I don't get you why should I check mtab?

Thank you.
