I had to remove it. > Alois, then you probably lost data with the gone disk. Backup time :-( Please make sure that you've got backups of /etc/lvmconf/* and /etc/lvmtab* before you proceed. There's 2 options: a. you get a replacement drive (which can be a loop device) of the same size (4G), run pvcreate on it, restore the metadata onto it (vgcfgrestore) and run "vgscan ; vgchange -ay" b. you implement LVM2/device-mapper and run "vgscan ; vgchange -P -ay", which will activate your VG without the missing drive. This solution enables you to retrieve the data still accessable _but_ won't let you change your volume group configuration. We are working on an enhancement supporting such changes.
