Bir sunucuda bir disk hatası oluştu ve sürücüyü LVM'den çıkarmadan önce değiştirdik.
Sunucu, her biri kendi ses grubuna (VG) sahip 4 fiziksel sürücüye (PV) sahiptir. Her VG'nin 2 veya daha fazla mantıksal hacmi vardır (LV'ler). Artık LVM, eksik sürücüden şikayet ediyor. Bu nedenle, sistemden silmemiz gerekenden öksüz kalan iki LV ile birlikte bir VG (vg04) sahibiz.
Sorun şu ki, herhangi bir LVM komutu çalıştırdığımızda şu 'okuma başarısız' hatalarını alıyoruz:

Kayıp VG ve LV'ler önemli değil, sadece onları kaldırmak istiyoruz.
Gördüğünüz gibi, bugüne kadar şanssız bir şekilde yapılan tüm önerileri denedik.
