[SOLVED] Automatic Mounting of Removable Devices

[bradleypariah]

I have two ext4 1TB HDDs (in addition to my system SSD), and although I am able to mount both drives just fine in Dolphin, they do not show up under System Settings > Removable Storage > Removable Devices > Attached Devices.
The drives are not listed under "Disconnected Devices" either. The window is completely empty.

I have checked the box for "Enable automatic mounting of removable media," and "Mount all removable media at login," but when I reboot, these drives are not mounted.

I don't know if I'm doing something wrong, or if I should submit a bug.

My removable drives appear under root/media/.

My removable drives appear under root/media/.

I know. And they are indeed there. I can mount them and everything. However, they are not able to be auto-mounted upon login, which is something I was able to do in 18.04. Nothing whatsoever shows up in System Settings > Removable Storage > Removable Devices > Attached Devices.
That window used to have a list of every drive the computer had ever seen.
There doesn't seem to be a way to manually add a location to be auto-mounted.

Although I wouldn't call this "solved" in the traditional sense, since I didn't actually do anything to proactively fix it, it is nonetheless fixed. After rebooting several times, the drives just showed up where they were supposed to.

External drives are in /media/(your name)/(name of drive)

Which brings up a question, the regular partitions that are mounted automatically are in /etc/fstab.
It used to be manually mounted partitions would be listed in /etc/mtab but I just saw that's no longer true.
Is there another place where I can find them?

Maybe this will give you the results youre looking for?

systemd-mount --list

They are for me on focal. /etc/mtab is just a link to /proc/self/mounts. A bare mount command lists the same mounts in the same order, formatted slightly differently. Both are illegible IMO.

The findmnt command produces a more readable listing. There's still too much dreck, so I filter its output to remove the sys, proc, dev, and run mounts, and reformat it a bit to suit the width of the terminal window.
For example

target                 source   fstype options
/                      sda2     btrfs  rw, noatime, ssd, space_cache, subvolid=2241, subvol=/@_focal
├─/mnt/top             sda2     btrfs  rw, noatime, ssd, space_cache, subvolid=5, subvol=/
├─/home                sda2     btrfs  rw, noatime, ssd, space_cache, subvolid=2242, subvol=/@home_focal
└─/media/john/pics     sdb4     ext2   rw, nosuid, nodev, relatime

That last one is a udisks mount requested by dolphin.
