Information in this document applies to any platform.
Here is the problem :
One is trying to mount a filesystem For eg. /trail in this case from Linux NFS server hardy on solaris 10 system and the mount point is /testing.
The goal is to mount with rsize=1048576,wsize=1048576 using either mount option in vfstab file or through regular mount command. The mount succeeds, but nfsstat -m shows the rsize/wsizes as 32KB (32768 bytes).
Entry in /etc/vfstab:
Output of nfsstat -m:
Attr cache: acregmin=3,acregmax=60,acdirmin=30,acdirmax=60
Output of mount:
The above output indicates it the mount parameters of rsize/wsize of 1MB were used, but nfsstat -m reports 32KB (see above).
