I was able to get the issue to occur again and got diagnostics with the NFS share stuck and diagnostics after I resolved it. Here is the process I went through. 1. Detected issue on Main Tab. says that the NFS mount has a size of 0. 2. Tried to force an unmount "umount -f /mnt/disks/192.168.1.10_Plex_Library" a. Get and error saying the device is busy "umount.nfs: /mnt/disks/192.168.1.10_Plex_Library: device is busy" 3. Tried to find what was keeping the mount busy. a. lsof | grep '/mnt/disks/192.168.1.10_Plex_Library' b. Get an error back "lsof: no pwd entry for UID 472" 4. Tried "fuser /mnt/disks/192.168.1.10_Plex_Library" and then "umount -f /mnt/disks/192.168.1.10_Plex_Library" which worked. 5. From the UD GUI I could remount the NFS share and all is back to normal. Attachments. 1349 is while the share was stuck. 1357 is after I resolved it with the steps listed above. deathstar-diagnostics-20200514-1357.zip deathstar-diagnostics-20200514-1349.zip

It only happens maybe once per month, but I will try to capture the diagnostics when it does. That or I might try to recreate it by blocking the rsync ports over the VPN to force it. Thanks,

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,
