Hi I am using Antergos, kde, as main computer as home nfs server. I share some folders from main computer and a share external usb disk.
The usb disk is mounted by fstab at boot on /mnt/seagate1. I would like to unmount the usb disk since it is not in use most of the time. However, if I try to unmount I get the message " one or more files are open by an application"
sudo fuser -m /dev/sdb
ps auxw|grep 403
root 403 0.0 0.0 34860 4312 ? Ss Oct18 0:00 /usr/sbin/rpc.mountd
leon 11588 0.0 0.0 10756 2076 pts/1 S+ 09:58 0:00 grep 403
Any suggestions please
