Subject: [mythtv-users] automating storage moves

I have a large 2T backend and (potentially) a small 160GB backend. I would love to use the small backend to record because it is close to where I have the tuner physically. Is there a way to automate migration from the storage group on the smaller BE to the storage group on the larger BE? I might just NFS mount up a dir on the larger BE but a storage migration from cron (or similiar facility) would be great.

If the point of your questions is balance space usage between the large and small spaces, I think that in .22 storage groups have a setting that will cover your needs. Just cross-mount both storage locations via NFS and add them to the default SG on the master BE.

--This is based on my observations on Mythbuntu 9.10

I have 160GB on one BE and 2000GB on the other. I dont want to run out of space on the 160GB BE while having free space on the 2000GB BE. That is really all.


That's what I thought, and I think MythTV should do that for you automatically using the setup I describe and the default settings in mythtv-setup. The setting you are looking for is in mythtv-setup>general Settings>"Storage Group Disk Scheduler" (Page 3): The default is "Balanced Free Space."
