I have had some NAS NFS time-outs: 'nfs: server 192.168.0.2 not responding, timed out'. Occured 3 times now and music stops. I use a synology DS114.
I addded actimeo=3600 to the mount flags: nfsvers=3,nolock,ro,actimeo=3600
Haven't had the issue since. Not 100% sure if issue is solved because it doesn't happen that often, but when it happens it keeps spamming this message every 5 seconds.
While checking if time-outs were solved I got the following at a certain point using dmesg:
- Code: Select all
