Description Amar Tumballi 2011-08-22 07:27:42 UTC

Tasks to be done:

* Handle a option 'runner-with-valgrind' in glusterd.c init(). (default value is 'disable'.

* Set a value in 'priv' if it is set (ie, enabled).

* If the 'priv->runner_with_valgrind' is set, in glusterd-utils.c, while starting glusterfsd, start it with 'valgrind --leak-check=full --log-file=LOGPATH/bricks/valgrind-<VOLNAME>-<BRICK_PATH>.log'

thats all.

May be with a 'option' in volume file, or with a CLI 'start' volume itself.

oChecked with glusterfs-3.3.0qa10. Started gluster, edited glusterd volfile and added the line option brick-with-valgrind on in the glusterd log file. Then started gluster, created a volume and started it.

These are the commands executred and the results.
