Re: guidance with hadoop on ceph

Hi Noah,

I made the change (added -x to !/bin/sh -x and uncommented it) to the mkcephfs file available in the source code, /home/varunc/ceph/src/mkcephfs in my case), and the output was what I pasted. find / -name mkcephfs did not return any other location for the file, so I guess there is only one mkcephfs script on my machine. Is there some other file I should be modifying?

Varun,

Are you sure the "-x" made it into the installed mkcephfs script that you are running? The output should be very large and verbose. Here are the first few lines of output--each command should be echoed to the terminal:

nwatkins@kyoto:~/projects/ceph/ceph/src$ ./mkcephfs -a -c ceph.conf
+ set -e
+ dirname ./mkcephfs
+ [ . = . ]
+ [ /home/nwatkins/projects/ceph/ceph/src != /etc/init.d ]
+ BINDIR=.

.. and on and on and on and on and on
