Como posso recuperar os dados / dados excluídos corretamente?

Question

Eu apaguei acidentalmente o volume thin de pve / data no proxmox. Muito próximo segundo eu percebi isso e eu tentei recuperá-lo como abaixo

lvremove /dev/pve/data
ls -lrt /etc/lvm/archive
head /etc/lvm/archive/pve_00059-189435924.vg
vgcfgrestore pve --test -f /etc/lvm/archive/pve_00059-189435924.vg

  TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated.
  Consider using option --force to restore Volume Group pve with thin volumes.
  Restore failed.
vgcfgrestore pve -f /etc/lvm/archive/pve_00059-189435924.vg --force

achei que foi restaurado corretamente, aqui está a saída

lvdisplay

Mas está inativo e não pode ser usado. Não consigo criar nenhuma VM nesse espaço. Mostra erro

  Using default stripesize 64.00 KiB.
  Thin pool pve-data-tpool (253:4) transaction_id is 0, while expected 54.
TASK ERROR: create failed - lvcreate 'pve/vm-107-disk-1' error:   Aborting. Failed to locally activate thin pool pve/data.

Estou tentando ativá-lo, mas não tenho sucesso.

lvchange -a y pve/data

Thin pool pve-data-tpool (253:4) transaction_id is 0, while expected 54.

Alguém pode me ajudar a resolver esse erro.

Tente executar partprobe ou até mesmo reinicialize seu dispositivo.
