In the 3rd
of the ONTAP 8.3.2 defaults series, we look at NFS Server defaults. There are a
lot of modify-able NFS server settings (especially since I’m including advanced
and diag level settings for completeness), this is not complexity though -
since in most cases the settings will be mostly perfectly fine set to defaults
- it’s configurability/flexibility/enablement/power for if/when you need to set
things differently to default.
All the
information presented in the table below can be got from::>
set diag
man nfs server modify
