Must have been a "pvcreate -ff /dev/hda4" to achive the recreation, while /dev/hda4 was a member of VG "debian" still. > > And now, I get: > > root@ttyp0[root]# vgscan > vgscan -- reading all physical volumes (this may take a while...) > vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of > volume group "debian" from physical volume(s) > vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created > vgscan -- WARNING: This program does not do a VGDA backup of your volume > group > > root@ttyp0[root]# pvscan > pvscan -- reading all physical volumes (this may take a while...) > pvscan -- inactive PV "/dev/hda2" is associated to unknown VG "debian" (run > vgscan) > pvscan -- inactive PV "/dev/hda3" is associated to unknown VG "debian" (run > vgscan) > pvscan -- inactive PV "/dev/hda4" is in no VG [23.85 GB] > pvscan -- total: 3 [57.24 GB] / in use: 2 [33.38 GB] / in no VG: 1 [23.85 > GB] > > How can I recover my vg?

Fetch and build them and run "vgreduce --removemissing debian".
