I am trying to mount a logical volume, under Debian 11.1.0. lsblk gives:
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sde           8:64   0 931.5G  0 disk 
sde1          8:65   0   243M  0 part 
sde2          8:66   0     1K  0 part 
sde5          8:69   0 931.3G  0 part
It is sde5 that I want access to. Trying to mount it:
root@debian:~# mount /dev/sde5 /mnt
mount: /mnt: unknown filesystem type 'LVM2_member'.
An internet search suggests use of lvdisplay to get a name that
can be used to mount it:
root@debian:~# lvdisplay
  WARNING: PV /dev/sde5 in VG debian is using an old PV header, modify 
the VG to update.
(and then lists disks for which there is no problem)
Any ideas on how I proceed from here?
