Proposed change to disk scheduler
|
|
I opened ticket #10946 because of an inconsistency I found with the
behavior of the Combination disk scheduler versus the Wiki
documentation
(http://www.mythtv.org/wiki/Storage_Groups#Balanced_Free_Space).
I then looked at the code (on 0.24.3, but I presume it hasn't changed
since) in mythbackend/scheduler.cpp, and understood why the behavior I
discuss in the ticket, which Jon Larson also reported in 2008, occurs
despite my setting SGweightLocalStarting to 0. Why does
comp_storage_combination() have hard-wire checks for local versus
remote filesystems? Isn't that what SGweightLocalStarting is for?
I patched scheduler.cpp with the following:
