gparted sees the partition 'lvm2', however Dolpin (File Manager) does not see the drive and therefore not mounted.

i reading "You used the exact same name (ubuntu-vg) for your new volume group as the old volume group. You must give them unique names. You can rename one of the groups using vgrename and its UUID."askubuntu.com mount-unknown-filesystem-type-lvm2-member

Find the UUID with vgdisplay and then rename the volume group:

sudo vgdisplay
[sudo] password for administrator: /dev/sde: open failed: No medium found /dev/sde: open failed: No medium found --- Volume group --- VG Name new_lvm2 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 5 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size <931,01 GiB PE Size 4,00 MiB Total PE 238338 Alloc PE / Size 244 / 976,00 MiB Free PE / Size 238094 / 930,05 GiB VG UUID 96qWN4-1W7c-Kwvx-zLeA-9u83-h18g-qBZYAH

vgrename <VG UUID> new_name
sudo vgrename 96qWN4-1W7c-Kwvx-zLeA-9u83-h18g-qBZYAH new_lvm3
[sudo] password for administrator: /dev/sde: open failed: No medium found Processing VG new_lvm2 because of matching UUID 96qWN4-1W7c-Kwvx-zLeA-9u83-h18g-qBZYAH Volume group "96qWN4-1W7c-Kwvx-zLeA-9u83-h18g-qBZYAH" successfully renamed to "new_lvm3"

gparted sees the partition 'lvm3', however Dolpin (File Manager) does not see the drive and therefore not mounted.

next i tried this: mount unknown filesystem type 'lvm2_member' . means:

sudo bash
vgrename 96qWN4-1W7c-Kwvx-zLeA-9u83-h18g-qBZYAH new_lvm4
modprobe dm-mod
vgchange -ay
lvscan
# Create the mount point directory:
sudo mkdir /mnt/new_lvm4/
# Mount:
mount /dev/new_lvm4/root /mnt/new_lvm4/

Some information about comand before:

• LVM Infos germanvgdisplay show information to VG (Physical volume)
• Modprobe
• vgchange -a n is deaktivated the VG - Infos i german

# vgchange -ay /dev/sde: open failed: No medium found /dev/sde: open failed: No medium found 1 logical volume(s) in volume group "new_lvm4" now active
# lvscan /dev/sde: open failed: No medium found ACTIVE '/dev/new_lvm4/swap_1' [976,00 MiB] inherit
# sudo mkdir /mnt/new_lvm4/
# mount /dev/new_lvm4/root /mnt/new_lvm4/
mount: /mnt/new_lvm4: special device /dev/new_lvm4/root does not exist.
root@administrator-kdeNeon:/home/administrator#
# mount /dev/new_lvm4 /mnt/new_lvm4/
mount: /mnt/new_lvm4: /dev/new_lvm4 is not a block device.
root@administrator-kdeNeon:/home/administrator# 

For this error i reading here:

and tried:

# mount --bind /dev/new_lvm4 /mnt/new_lvm4/
root@administrator-kdeNeon:/home/administrator# 

however Dolpin (File Manager) does not see the drive and therefore not mounted.

any idea?

As I told you on matrix: There is no such option to mount a swap device. If you did not see any data LV in your VG then there is nothing to recover.
