Is it possible to increase the number of vxfsd processes?

Hi,

Try increasing max_thread_proc parameter.

Here is the doc for more info

Re: Number of vxfsd deamons

hi,

I don't think it is possible. vxfsd is started in kernel mode (pid=0).

Question is why do you want to increase the number??
I have so many busy systems which handle terabytes of data and we never had a case where the vxfsd is more than one.

If your processes are threading a lot, you can increase the thread related parameters: nkthread and max_thread_proc.
To check the current thread usage: from a hp doc -
You can use the following q4 script to display the number of running kernel
threads.

Note: This script also allows you to tune the 'nkthread' tunable
parameter.

#!/usr/bin/sh
/usr/contrib/bin/q4pxdb /stand/vmunix
/usr/contrib/bin/q4 /stand/vmunix /dev/mem <<-EOF
load struct kthread from kthread max nkthread
keep kt_stat != 0
EOF

Sample program output:

loaded 499 struct kthread's as an array (stopped by max count)
kept 132 of 499 struct kthread's, discarded 367

Note: 132 is the number of running kernel threads.
499 is the 'nkthread' value.
