centos 7.0 lvremove 이후 데이터를 복구하는 방법은 무엇입니까?

나는 어리석은 짓을 해서 다음 명령을 실행하여 논리 볼륨을 삭제했습니다.

lvremove -f /dev/cl_dhcppc4/home

그러나 즉시 백업 파일에서 lvm을 복원했습니다.

vgcfgrestore --file /etc/lvm/archive/cl_dhcppc4_00001-1231497433.vg cl_dhcppc4

하지만 이 논리 볼륨을 마운트하고 그 안에 있는 데이터에 액세스할 수 없습니다. lvm과 해당 fdisk를 볼 수 있습니다. 결과는 다음과 같습니다.

[root@localhost lk]# lvdisplay -m

LV 경로 /dev/cl_dhcppc4/home에서 데이터를 복원해야 합니다. Fdisk는 다음과 같은 결과를 제공합니다.

디스크를 마운트하려고 하면 nfs, ext3 파일 유형에 대한 파일 시스템 유형 오류가 발생합니다.

[root@localhost lk]# mount /dev/mapper/cl_dhcppc4-home /hd
mount: /dev/mapper/cl_dhcppc4-home is write-protected, mounting read-only
mount: unknown filesystem type '(null)'

[root@localhost lk]# mount -t nfs /dev/mapper/cl_dhcppc4-home /hd
mount.nfs: remote share not in 'host:dir' format

[root@localhost lk]# mount -t ext3 /dev/mapper/cl_dhcppc4-home /hd
mount: wrong fs type, bad option, bad superblock on /dev/mapper/cl_dhcppc4-home,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
