Loss off network shares on 8.2

[TheOldPresbyope]

Could be useful. What format is the file system on the attached USB drive?

ExFAT

Looks like exfat format is not supported by NFS

My drives are mostly fat32 (VFAT) which apparently works with NFS. I'm guessing that formats like NTFS etc are not supported by NFS either. 

I'll update the help for upcoming 8.2.1

Interesting. To test this I reformatted a USB thumbdrive to exfat and wrote some tracks to it.

Here's a snippet from the moOde 8.2.0 syslog when I started the NFS service with this USB drive mounted.

Code:

Sep 22 20:44:05 m82arm64 systemd[1]: Starting NFS Mount Daemon...

Sep 22 20:44:05 m82arm64 systemd[1]: Stopped NFS Mount Daemon.

So service flags the drive as not supporting NFS export. Too bad the service then fails and stops. This accounts for the behavior which was puzzling me.

OTOH. I then reformatted the USB drive as NTFS and wrote some tracks to it.

Here's the relevant syslog snippet this time.

Code:

Sep 22 21:52:30 m82arm64 systemd[1]: Starting NFS Mount Daemon...

Sep 22 21:52:31 m82arm64 systemd[1]: Finished NFS server and services.

This time the NFS service is running and the USB drive is exported, can be detected in a second player, mounted as a music source, etc.
