I have an IPsec VPN setup between sites and mount a remote NFS share from UnRaid using the UD plugin. I use this for remote backups. This works great 99% of the time. Occasionally there is a network issue and the NFS share is no longer accessible. It seems like the system pings the remote system to confirm the share is still active and if it fails it takes the share offline. Then both the UD plugin and UR act strange. Once here the only way to fix it is a full system reboot. The strange behavior I see is if I try to use UD to unmount or remount the share the system just hangs. If I do a simple 'ls' command in the /mnt/disks folder the terminal just hangs as well. It doesn't happen daily, so a full system reboot isn't the end of the world but it is still annoying. Hopefully I am just missing something and there is an easy fix.
1. Is there a way to force UD to retry a NFS mount after a previous failure?
2. Is there a way to reload just the UD plugin without a full system reboot?
3. Is there a better way to mount this remote NFS share that is more tolerant of network hiccups?
Thanks,
