I changed the filename to "passwd2" because I wasn't sure what impact this would have on my /etc/passwd file.
The dtrace script has hopefully no impact in the target file.

Was I supposed to run fake_inode.d from within /etc?
From anywhere you like.

I created fake_inode.d and passwd2 inside /data, and ran the script from there. It has been saying this for a while:
This is the expected output. You should leave the script running for the inode renumbering hack to persist.
As Bartus11 already stated, just use another terminal to experiment with you program expecting a large inode number.
Hi,
If inodes need to be 3-4 times greater than fd.file-max. Can you modify the current inode in the filesystem? Can you modify it on the fly? Or only in the creation of FS.
I'm using redhat ent 4.
Thank you for any comment you may add. (1 Reply)

priclass.d
priclass.d(1m) USER COMMANDS priclass.d(1m)NAME
priclass.d - priority distribution by scheduling class. Uses DTrace.
SYNOPSIS
priclass.d
DESCRIPTION
This is a simple DTrace script that samples at 1000 Hz the current thread's scheduling class and priority. A distribution plot is printed.
With priorities, the higher the priority the better chance the thread has of being scheduled.
This idea came from the script /usr/demo/dtrace/pri.d, which produces similar output for priority changes, not samples.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
This samples until Ctrl-C is hit.
# priclass.d
FIELDS
value process priority
count number of samples of at least this priority
SCHEDULING CLASSES
TS time sharing
IA interactive
RT real time
SYS system
FSS fair share scheduler
BASED ON
/usr/demo/dtrace/pri.d
DOCUMENTATION
DTrace Guide "profile Provider" chapter (docs.sun.com)
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
priclass.d will sample until Ctrl-C is hit.
