显示sdm中卸载的路径
因此，我尝试将 /dev/sdm 安装到 /mnt/grid/11 但输入命令后
mount /dev/sdm /mnt/grid/11
回mount: /dev/sdm is not a valid block device
还检查了fdisk /dev/sdm
回fdisk: cannot open /dev/sdm: No such device or address
但实际上设备 sdm 仍然存在，因为我可以访问该目录
ll /dev/sdm
brw-rw---- 1 root disk 8, 192 Mar 6 07:02 /dev/sdm
问题是为什么它说 /dev/sdm 不是有效的块设备，尽管系统似乎可以识别该设备。
谢谢
