Thanks Vindoh for replying to my question! I will add the options to /etc/fstab as you mentioned. But is const.h the only file I should change to make the NFS server support 32K size? Is there an easy way to verify if the NFS server is indeed serving NFS clients with 32K? Should I also modify const.h on all NFS client machines also? I'm using RHEL3 and the kernel version is 2.4.21-27.0.1.ELsmp. It looks like this patchset didn't make it into kernel version until 2.4.27-xx or so. Is it true? Thanks again!
