I am trying to obtain some clarification on Storage Groups in mythtv-setup. After a search of the mailing list and google, no documentation has appeared.<br><br>In mythtv-setup -> Miscellaneous Settings -> File Management Settings -> Storage Group Disk Scheduler there are three options:<br>
<br>1. Balanced Free Space<br>2. Balanced Disk I/O<br>3. Combination<br><br>Field Description: This setting controls how the Storage Group scheduling code will balance new recordings across directories. 'Balanced Free Space' is the recommended method for most users.<br>
<br><br>Under <a href="http://www.mythtv.org/docs/mythtv-HOWTO-9.html#storagegroups">http://www.mythtv.org/docs/mythtv-HOWTO-9.html#storagegroups</a> and <a href="http://www.mythtv.org/wiki/Storage_Groups#Storage_Groups">http://www.mythtv.org/wiki/Storage_Groups#Storage_Groups</a> there is no mention of these categories which leads me to believe this documentation is old.<br>
<br>Option #1 seems logical that the recording directory will be chosen based upon the partition with the most amount of free space.<br><br>Option #2 cannot be assumed, but from the wiki:<br>[START OF WIKI]<br>MythTV will balance concurrent recordings across the available
directories in a Storage Group in order to spread out the file I/O
load. MythTV will prefer filesystems that are local to the backend over
filesystems that are remote until the local filesystem has 2 concurrent
recordings active or other equivalent I/O, then the next recording will
go to the remote filesystem. The balancing method is based purely on
I/O, Myth does not try to balance out disk space unless a filesystem is
too low on free disk space in which case it will not be used except as
a last resort.<br>[END WIKI CONTENTS]<br><br>Option #3 does not seem to have any documentation at all on the internet.<br><br>Please provide your understanding of the above options and I will update the wiki article to reflect this thread and further improve mythtv support and documentation.<br>
