> Multiextent support seems to be back by default with ESXi 6.5. The checks
> done in VMware.pm::check_multiextent are generating warnings and a critical
> message:
> {noformat}

> VMware.pm:check_multiextent|6807| DO THE FOLLOWING TO FIX THIS PROBLEM:
> VMware.pm:check_multiextent|6807| Enable the module by running the following
> command on each VMware host: 'vmkload_mod -u multiextent'
> VMware.pm:check_multiextent|6807| Add a line containing 'vmkload_mod -u
> multiextent' to /etc/rc.local.d/local.sh on each ESXi host
> VMware.pm:check_multiextent|6807|

> The version should be checked in the subroutine and the checks bypassed if >=
> 6.5.
