It's an nfs limitation. Reconfig your server and change this option:
"include/linux/nfsd/const.h" in the kernel source shows the following
definition
/*
* Maximum blocksize supported by daemon currently at 8K
*/
#define NFSSVC_MAXBLKSIZE 8192

I have also tried to put them in the localoptions setting in the autofs
init file ( localoptions='rsize=32768,wsize=32768' ) on both the nis
master and on the client machines.
I also tried to specify these options in the auto.master file on the nis
master (the client machines don't have auto.master files because they
read the nis master's file ) ( /etc/auto.home
--timeout=43200,rsize=32768,wsize=32768 )
I have also tried to use lower settings such as 16384
however when I look in /proc/mounts on the client machine it is either
mounted with 4096 or 8192
Are you using NFSv3? As far as I know I think 8192 is max for NFSv2, at
least for most of the NFSv2 servers I know.
Try doing the mounting without using autofs. If the same thing happens,
it's an NFS issue, not an autofs issue.
