这样格式化会有什么后果?
[root@localhost ~]# ll /dev/sdb*
brw-rw----. 1 root disk 8, 16 3月 16 22:40 /dev/sdb
brw-rw----. 1 root disk 8, 17 3月 16 22:30 /dev/sdb1
brw-rw----. 1 root disk 8, 18 3月 16 22:30 /dev/sdb2
brw-rw----. 1 root disk 8, 19 3月 16 22:30 /dev/sdb3
我把/dev/sdb给格式化了,这回有哪些后果?
mkfs.ext4 /dev/sdb
mke2fs 1.41.12 (17-May-2010)
/dev/sdb is entire device, not just one partition!
无论如何也要继续? (y,n) y
