What's the maximun values NetApp support?</P><P>2. If I manually specify larger values on Linux, is it correct it will negotiate to the max values when it reconnects?</P><P>&nbsp;</P><P>Thanks,</P><P>&nbsp;</P><P>&nbsp;</P> Wed, 04 Jun 2025 18:07:59 GMT https://community.netapp.com/t5/ONTAP-Discussions/NFS-rsize-wsize/m-p/125883#M27129 ACHOU_SIMG 2025-06-04T18:07:59Z https://community.netapp.com/t5/ONTAP-Discussions/NFS-rsize-wsize/m-p/125896#M27134 <P>TR-4067 covers the max rsize/wsize on page 16.</P><P>&nbsp;</P><P><A href="http://www.netapp.com/us/media/tr-4067.pdf" target="_blank">http://www.netapp.com/us/media/tr-4067.pdf</A></P><P>&nbsp;</P><P>Max xfer size is 1MB.
