Agora estou tentando recuperar os dados da invasão.
Eu usei 3 * 8TB HDD como RAID5.
De alguma forma, talvez um ou dois deles estejam quebrados.
Nesse caso, deparei-me com o mdadm e pvscan, lvscan usecase.
O que eu fiz é assim abaixo.
root@ubuntu:~# cat /proc/mdstat
Personalities : [raid1]
md127 : inactive sdf2[2](S)
523760 blocks super 1.2
md0 : inactive sdg1[1](S) sdd1[4](S) sde1[0](S)
12570624 blocks super 1.2
md1 : inactive sdb2[2](S)
523760 blocks super 1.2
em seguida, ative cada unidade.
mdadm -R /dev/md0
mdadm -R /dev/md1
mdadm -R /dev/md127
Todas as unidades são ativadas.
root@ubuntu:~# cat /proc/mdstat
Personalities : [raid1]
md127 : active (auto-read-only) raid1 sdf2[2]
523712 blocks super 1.2 [3/1] [__U]
md0 : active (auto-read-only) raid1 sdg1[1] sde1[0](F)
4190208 blocks super 1.2 [4/1] [_U__]
md1 : active (auto-read-only) raid1 sdb2[2]
523712 blocks super 1.2 [3/1] [__U]
então eu tento pvscan no entanto estes erro happne. o que posso fazer a seguir para recuperar meus dados? por favor me dê qualquer ajuda.
