check_mk How to fix:Disk Mount Changes showing error

Sometimes few hosts in my check_mk build showing Disk Mount error.

For example:
"Mount options of / - - - - CRIT - mount options are
> > > acl,barrier=0,data=ordered,errors=remount-ro,noatime,rw,user_xattr,
> > > expected are barrier=0,data=ordered,errors=remount-ro,noatime,rw"

But there isn't any changes recently.

I just su to my site and refresh the hosts manually:

# su - [site_name]
# cmk -II [$host_name]
# cmk -R

Restart the check_mk, that will make the nonsense error goes away.
