Thanks again Ken for your e-mail. Yes my system is basically the same as yours.. I'll plod along with using the bookmarks until Uwe has a chance to work on it.. Programmer's  amaze me, I wish I went down that road when I was younger. 

Thanks again and all the best to you.. Greg

Hello again Greg,

I think I misunderstood. Are you running gnome-commander on the same machine as 
the drives are installed? If so that should be much simpler. I connect to my 
servers across my network. For local file systems the bookmarks approach is 
probably the best workaround. Ctrl-D will bring up the bookmarks dialog.

For what it is worth, here is how I have some "devices" configured in my older 
version of g-c on CentOS 7.  They are simply pointing to file systems just like your 
video1, video2 etc. Try this simple setup. It might work. Sorry I cannot get it as an 
in-line image. It is attached.


I don't have g-c on an Ubuntu 20.04 physical machine at the moment. I will try 
and get one setup with the latest g-c and see what I can see.

Hi Ken,

     Thanks for the detailed e-mail.. I struggle when I have to do
things out of the ordinary on linux. My drives are mounted through
Fstab. I have been running it this way for well over 15 years and it has
served me well. Here is a copy and paste of my fstab.

It runs 24/7.. All nine drives are on the same computer,nothing too
extreme...

I do have the drives bookmarked and that works ok,but not as nice as the
devices buttons.. I did get G-C working using devices,but as soon as I
quit the program it lost all the mappings.. When I read you were working
on a snap for GC I figured that was the answer. I tried several other
commander type programs,but they aren't GC..

Thanks again, Greg

Hello Greg,
How are you sharing the drives in your media server (nfs, samba, something 
else)? I have a somewhat similar situation and this is how I handle it.
I have 3 data servers. Each one has drives in pairs which I keep mirrored. The "a" drives 
in each pair are exported with nfs. The b drive in each pair is the backup. As I do not need access 
to the data at all times, I only bring up a sever when I need it. This adds a little wrinkle which 
you might not have. If I mount an nfs export from the Mate desktop (on CentOS 7 in this case) the 
file managment system "caja" goes berserk if the server shuts down with the mfs export 
still mounted. I therefor have server-on and server-off scripts which I run as needed.
On my CentOS workstation I have the following directory structure to access the 
server data:
/data/
/data/servers/
/data/servers/data14.1/
/data/servers/data14.2/
/data/servers/data14.3/
/data/servers/data18.1/
/data/servers/data18.2/
/data/servers/data22.1/
/data/servers/data22.2/
These are the mount points for drive 1a on server t14, 2a on server t14 etc. 
Here is the script to mount server t14:
#!/bin/bash
sudo mount t14:/media/data14.1a /data/_servers/data14.1
sudo mount t14:/media/data14.2a /data/_servers/data14.2
sudo mount t14:/media/data14.3a /data/_servers/data14.3
echo mounting finished
sleep 10
exit
And the unmount script:
#!/bin/bash
sudo umount --force -vvv /data/_servers/data14.1
sudo umount --force -vvv /data/_servers/data14.2
sudo umount --force -vvv /data/_servers/data14.3
echo un-mounting finished
sleep 10
exit
You could create a shortcut in Gnome-Commander to access the top of the mount tree 
/data/servers or even a shortcut for each drive. As g-c is not attempting to make the 
connection - and thus not using gnome-vfs - I would not expect any issues. This is not 
quite as handy as "device" buttons but...
If your media server is on-line essentially full time you might wish to look 
into autofs. It will automatically mount nfs exports when accessed. However, I 
have had bad luck using it when the servers are not on-line.
I have given myself NOPASSWD access to the sudo mount and umount commands in 
visudo so I am not bothered by being asked for a password each time I run a 
script. Ask if you need help with that. If you are using Samba (smb) to share 
the drives you could probably setup something similar on your Ubuntu 20.04 
machine. It has been a while since I have done that.

Thanks for the advice. I may take me a while to try them.. The devices I
am trying mount are  nine  Hard drives,each one is named Video 1-Video9.
This is on my media server.. I hope I can get it to work. I have
resisted up grading to Ubuntu 20.04,because of GC. If I can't get it
going,I may return to Ubuntu 18.04.. I have tried several commander type
file managers,but nothing compares to GC..
Thanks for the suggestions..

I'm also misusing the device buttons as graphical bookmarks by creating 
'pseudo-devices', which means, instead of the previous mount command, i'll 
insert into the 'device' field just a


/dev/null && cd
and it will change directory into what is configured as (not really a) 
mountpoint.
For example, insert '/tmp' there and you'll have a fast switch to the temp 
folder.
