Hey all,
Here's a patch that adds a layout parameter to sys_create. The idea is that users may want to specify exactly which servers are chosen for a file to be distributed over, or use an algorithm (like in-order round-robin). So in the layout structure, a layout algorithm must be defined. The current algorithms are:
none: order the datafiles according to the server list.round-robin: choose the first server randomly, and round-robin in- order of the server list.
random: order the datafiles randomly (with unique servers). list: provide an exact list of serversFor the list algorithm, a separate list structure must be specified, which is a count of servers and their BMI address references. The patch includes functions to get all the server BMI addresses and map them to hostnames.
Let me know what you think. -sam
