Ok - here's my situation. I've got a typical unRaid setup, with a cache drive. I have a share exported via NFS to my mythtv server to store TV recordings. (mythtv is DVR software) No problems there - myth writes/reads without any issue over my GB network.
After a TV show records, a script runs to move the randomly named *.mpg file into an episode-based file.
For example, the file that used to reside at:
/mnt/beast/mythtv/recordings/1051_20131030235900.mpg is renamed and moved to
