I could not mount some LVM ext4 filesystems on a server earlier this week and
was trying to work out what I had to do to make it work.
I had booted into break=premount ( added to the end of the linux line in Grub )
to fix an error in /etc/fstab that caused root from mounting
I could access volume groups via the LVM command:
% lvm vgs
VG #PV #LV #SN Attr VSize VFree
vg0 1 4 0 wz--n- <99.50g <28.11g
vg1 1 1 0 wz--n- <500.00g 1020.00m
but when I ran ,
% mount /dev/mapper/vg0-root /tmp/a
I recall a message stating the fs count not be mounted because of wrong file
system type.
1) Make sure the LV is activated, e.g. with vgchange -ay
2) The mount command in the initramfs may require to specify the
filesystem type explicitly with -t.
