о ужас! все сломалось! блин, забыл vgreduce перед pvremove! не паникуем:

# pvcreate /dev/sda2 --uuid 'L5hT2P-fPEa-Lumy-agV1-Aluk-PqTK-OATJJO'
  Couldn't find device with uuid 'L5hT2P-fPEa-Lumy-agV1-Aluk-PqTK-OATJJO'.

тут обязательно указываем uuid из предидущих сообщений если забыли! и теперь проверим:

# pvdisplay
  --- Physical volume ---
  PV Name               /dev/sda2
  VG Name               pve

фух! тома на месте! теперь делаем как надо:

# vgreduce pve /dev/sda2
  Removed "/dev/sda2" from volume group "pve"
# pvremove /dev/sda2
  Labels on physical volume "/dev/sda2" successfully wiped

теперь без всяких вопросов!
на будущее: если задали вопрос – НЕ ТОРОПИТЕСЬ ГОВОРИТЬ YES !!!
