卸载并重启后磁盘消失

我的磁盘消失了：

# df -h
Filesystem                    Size  Used Avail Use% Mounted on
.
.
/dev/mapper/vg1-osblv02       5.0T   61G  4.7T   2% /data/osb-pool-1
/dev/mapper/vg01-osblv01      1.8T   45G  1.7T   3% /data/osb-pool-0
 .
 .

但在我强制卸载dev/mapper/vg1-osblv02并重新启动后，我再也看不到它了：


# df -h
Filesystem                    Size  Used Avail Use% Mounted on
 .
 .
 .
#

因此重启后我看不到有关此内容的更多信息：

重启后：

# lsblk

当我检查 /etc/fstab 时，我得到了这个：
