Minidlna
Minidlna is a dlna server with a small footprint, originally designed to run on consumer NAS devices. Installation is fairly simple.
For this setup we will use GlusterFS as the file store backend.
Software
Start by installing minidla
apt-get install minidlna
Filesystem
Configure your system as a GlusterFS client, so you have the following in your fstab.
/etc/glusterfs/video.vol /srv/video glusterfs defaults,_netdev,rw 0 0
Configuration
Configuration is in /etc/minidlna.conf. Configure a directory to export.
media_dir=V,/srv/video
Set the network interface to export on
network_interface=eth0
When minidlna starts, you will get the following in your log
monitor.c:218: warn: WARNING: Inotify max_user_watches [8192] is low or close to the number of used watches [6] and I do not have permission to increase this limit. Please do so manually by writing a higher value into /proc/sys/fs/inotify/max_user_watches.
If you want to increase this value to accomodate minidlnas request, pick something above 100000, and add it to /etc/sysctl.conf.
fs.inotify.max_user_watches = "131072"
