[linux-lvm] Vgscan problem

[Heinz Mauelshagen]

Hi Patrick,

the error number tells you that the amount of logical extents found in
the mapping tables for e specific logical volumes differs from the
amount expected -> metedata inconsistency.

Could you provide a complete "vgscan -d" output to better anaylze this?

In the meantime please save your /etc/lvmconf/ VGDA backup files to
enable you to restore a consistent state of your VGDAs to the PVs.
Please read vgcfgrestore(8) for this issue.
