Noah,

Thanks, turns out I had indeed changed the wrong file. Anyways, now I have changed the correct file. Since the output was too big to be captured and pasted here, I am attaching the file. Hope its ok.

Is there some other file I should be modifying?

To make sure you are editing the correct file, run

#> which mkcephfs

which will print the full path to the script being run.

The first few lines of the top of the script should look like (with the #):

#!/bin/sh -x
#
# mkcephfs

If for some reason it is still not working, you can add an echo statement to confirm:

#!/bin/sh

set -x
echo "I should be seeing this"

# mkcephfs
