Show LVM2 PV file systems and notice that the lvm2 package has to be installed in order to mount them #556

Open davidhedlund opened 1 year ago

davidhedlund commented 1 year ago

[I've also proposed this solution for GNOME: https://gitlab.gnome.org/GNOME/gnome-panel/-/issues/49]

These GNU/Linux distributions has LVM2 PV installed by default.

However, Ubuntu does not inform that it cannot mount LMV2 PV without the lvm2 package installed. So it's moderately difficult for people to find why disk drives with Ubuntu Server, nor Trisquel, are not mounted in Ubuntu.

Expected behaviour

I expected that the device is listed, and when you click on it a pop-up dialog box show something like gparted (see below): "The following list of software packages is requried for lvm2 pv file system support: lvm2."

LVM-on-LUKS, without the lvm2 package installed

It can be a disconcerting experience to enter a password and then suddenly the file system thumbnail disappear. This can lead people to believe that they have either entered the wrong password or that the file system is damaged, which could result in them deciding to delete it in a worst-case scenario.
