I'm running Kybuntu 20.04. I'm trying to mount a Synology NAS (Network Attached Storage) unit via a symlink. On bootup the unit doesn't get mounted, which is the problem. However, once my system gets going I can do the mount explictly or even with mount -a.
I've set up the symlink with
ln -s /Music /mnt/synology
I did that just once, on a previous login. /etc/fstab contains the line
192.168.0.21:/volume1/NAS /mnt/synology nfs defaults 0 0`
Why doesn't the filesystem at 192.168.0.21 get mounted on every reboot?
The problem is trickier than I realized at first. _netdev will ensure that the network is up and running, but will not ensure that the Synology unit is fully available.It can take several seconds at least from when the network comes online to when the Synology unit is fully accesssible. I don't know how to test for that, since even when the Synology box is fully connected to the network there might be additional delays within the box.
defaultsis just a placeholder for when you don't want to declare any options yourself. But as soon as you name any option, you don't need to putdefaultsthere too, any more. So I believe, in this case a single_netdevin the fourth column could suffice. – Levente May 27 '21 at 02:09
