I had this config, but several months ago! How did you manage to have metadata for 4 PVs? Did you eventually restore an old metadata backup with vgcfgrestor(8)? > A few months ago I added a new disk, did a pvmove and removed a old disk. With remove you mean "vgreduce data /dev/TheEmptyPV"? If you just removed the physical device and your VG stayed online since then, vgscan now can't find it any longer. In this case, you need to pvcreate+vgcfgrestore a free disk and run ""vgreduce data /dev/TheFreeDisk" > So temporarly there were 4 disks in my VG. > > One way to fix my problem could be, that i somehow fake a pvmove. so only > the metadata is updated.
