If you have your HOME (and, therefore $HOME/.mythtv ) directory mounted
over NFS, or if you have the Images Storage Group directories or the
MythVideo (local) directories (if you're not using Storage Groups)
mounted over NFS, make sure you're *not* configuring those mounts the
way we've recommended you configure your recordings directories (
http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.9 ). You need to
enable NFS file attribute caching on the Images/MythVideo directories.
So do /not/ use actimeo=0 or noac and make sure, if you do modify
actimeo or acregmin, acregmax, acdirmin, or acdirmax that you use
appropriate values (as can be found through trial/error if you really
feel you need to adjust them). NFS defaults should be appropriate,
though. You /definitely/ need at least actimeo=1, but higher is
probably better.
For the recordings directories, actimeo=0 is useful to allow Live TV to
work properly. It will kill performance, though, if you use it on
Images/MythVideo directories.
