Hi, 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. Did I miss a module that had to be loaded for this to work, or is premount the wrong place to try this? ( In the end I rolled back to a snapshot that worked, but I should know for the future. ) Regards, S Sent from phone, thus brief
