QFS mount options not getting noticed.

Hi I have a small issue it seems that none of my QFS directives are getting noticed im not sure if this is true or not but this is what I have tried and i am unable to verify that these mount options are actually taking effect..

This is QFS Version 4 revision 4.0.26FA

in my /etc/opt/SUNWsamfs/samfs.cmd I have the following options

fs = qfs1

nosuid

sync_meta = 0

qwrite

readahead = 4096

writebehind = 1024

after mounting my file system why are these options not listed in mnttab

qfs1/qfs1samfsdev=1d800361048280993

using dd/time to write data to this file system im getting the exact same performance no matter what options I set. another reason why I think these options are being ignored is the following

if I set for example fs = qfs1 and high = 70 low = 30 when I check samu [m] option I dont see those values reflected in the m output so what im asking is there anyway to verifty that my mount options are being set occordinly ?

Yes I did use mount -o nosuid,qwrite,etc.. /qfs1 still no difference and even placing the options in vfstab seems to not make any difference.

last but not lease if i do a samtrace -V while mounting my /qfs1 filesystem I see the following

00100000 readahead(1048576) << still seems to use the default values 1024

00080000 writebehind (524288)<<-- 512 look @ my samfs.cmd file this should but not the value.

Any assistance would be nice.

Hi There! Sorry, it took so long to get back to you. This should help:

The samu N display shows all the mount options. You can also use the samfsinfo command to see file system build information. If the samfs.cmd options are not being picked up, make sure the file is formatted correctly (no odd characters) and is in the proper location, /etc/opt/SUNWsamfs/samfs.cmd . Then "pkill -HUP sam-fsd" to assure the daemon has picked up the file's contents, and then mount the file system.
