Change number of open files in init script
On a busy system with multiple OSD's your OSD's can reach the max number of open files.
It should be useful IMHO if the init script changed this limit, for example:
ulimit -n $(($num_osd_on_this_machine * 16384))
We might also choose to use a default value of 131072 for example and hard code it in the init-script.
NUM_OPEN_FILES=131072 if [ -f /etc/default/ceph ]; then . /etc/default/ceph fi ulimit -n $NUM_OPEN_FILES
Although it is a trivial task to do this, it would make deploying Ceph a bit easier.
