Resolution
Login to the NAS proxy.
Shares are mounted under:
/var/Phoenix/NAS/mountpoint/ <mount name>.To check for the stale entries of any mounted shares, run the command :
df -h. This will give us an output for stale file handles for /mnt on NAS proxy.Unmount the share with this command: umount /var/Phoenix/NAS/mountpoint/<mount name>
Initiate a backup after doing the above steps.
📝 Note
Reboot will help in this condition if you are able to unmount the drive.
