Eu instalei um armazenamento LVM no meu computador e eu tinha informações muito importantes dentro de /HFT .
Aqui está a maneira que eu instalei esse armazenamento LVM:
-
sudo pvcreate /dev/sdb1 /dev/sdc1
-
sudo vgcreate VG /dev/sdb1 /dev/sdc1
-
sudo lvcreate -n LV -L 3T VG
-
sudo mkfs .ext3 /dev/VG/LG (pode ser .ext4 )
-
mkdir /HFT
-
sudo mount /dev/VG/LG /HFT
Antes de reiniciar, obtive um bom armazenamento de 3 TB, pude ver claramente com df -h . Agora, depois de reiniciar o meu computador, se eu fizer df -h , eu tenho

Agora, /HFT ainda existe, mas está vazio.
Não sei se perdi tudo. Existe uma maneira de restaurar informações? Por que todo o procedimento foi esclarecido depois que eu reiniciei meu computador? Qual é a maneira correta de tal erro não ocorrer novamente no futuro?
