I said forked-daapd isn't maintained. openmediavault-forkeddaapd (the plugin) is maintained.
I use google to search the forum. RTC thread
No idea why that filesystem doesn't show up for use with shared folders.
Where should I ask for more information about openmediavault-forkeddaapd when it fails?
I followed the guide put up by tekkb, corrected /boot/config.txt as outlined by DougieLawson
Now RTC works –thanks–!
As for the invisible volume, would there be a command-line or GUI way to refresh the list of available volumes / shared folders?
If that help, the /dev/sda3 device is mounted but not referenced, unlike /dev/mmcblk0p3. Does this "referenced" refers to file indexing, or something else?
