Hi,
ONTAP 9.1RC1
RHEL 5.7
I just migrated from Isilon to NetApp and I notice from a Linux 5.7 host, it used to have much larger rsize/wsize (128k/512k) but now has 64k/64k when mounted onto NetApp.Nothing changed on the Linux side so I believe the sizes are negotiated.
1. What's the maximun values NetApp support?
2. If I manually specify larger values on Linux, is it correct it will negotiate to the max values when it reconnects?
Thanks,

TR-4067 covers the max rsize/wsize on page 16.

Max xfer size is 1MB. The server defaults to 64k. You'd have to change the option on the server to get larger write and read sizes.
