i started off with Lubuntu 13.XX. initially setup the box as a torrent/file server box. for whatever reason, i needed to make changes, and moved to 14.04 but still using the same hardware in the torrent/file server. obtained larger hdd, and decided to update to 14.10 on that drive. everything was working properly for the last 2 weeks without fail until yesterday.
i setup lubuntu with no problem. update/upgrade - no problem. configured samba - no problem. normally use Kodi media player (sometimes VLC) from windows 7 to access lubuntu file server. without warning, it was not able to play some files that i had recently copied to the box. it also stopped playing other files it had always been able to play. i am still able to navigate and view all folders, but the files would not even play with VLC. most files were copy/cut & pasted to the drive via external USB device. i did not think that it should, but is it possible that copy vs cut would affect anything?
the one thing that i did differently was that i ran additional system updates on this box when i had not previously done it under the other configurations. is it possible that new updates broke some file access permissions? naturally i am able to play the videos directly from the lubuntu box itself. i find it strange that files that were recently copied within the same sub folders did not work. for example; season 3 was downloaded and seasons 1&2 were copied from another source, but only season 3 worked since it was originally on lubuntu.
any ideas before i destroy everything and rebuild?
