Today's own virtual machine disk is completed, so I would like to add a disk, when mounted to find an error you must specify the filesystem type. (Note: My system environment is lcentos6.3 installed in VirtualBox virtual machine)
It turns out that the disk does not have a format partition resulting in the following actions:
1 First look at the current system situation, the new disk is SDB
code is as follows |
&nbs P; |
[root@test ~]# lsblk name & nbsp; MAJ:MIN RM SIZE RO TYPE mountpoint sr0 11:0 1 1024m 0 rom sda 8:0 0 8g 0 Disk ├─sda1 8:1&NBsp; 0 500m 0 part/boot └─sda2 8:2 0 7.5g 0 part ├─volgroup-lv_root (dm-0) 253:0 0 6.6G& nbsp 0 lvm / └─volgroup-lv_swap (dm-1) 253:1 0 992m 0 lvm [SWAP] sdb 8:16 0 8g 0 disk |
2) try to mount, error
The code is as follows |
|
[Root@test ~]# Mount/dev/sdb/disk |
Mount:you must specify the filesystem type
3) Format the disk
code is as follows |
&nbs P; |
[root@test ~]# mkfs.ext3/dev/sdb mke2fs 1.41.12 (17-may-2010) /dev/sdb is entire device, not just one partition! Do you want to continue anyway?

[root@test ~]# |
4) Successful Mount
The code is as follows |
|
[Root@test ~]# cd/disk/ [Root@test disk]# ls Lost+found
|
5) Increase boot boot
code is as follows |
&nbs P; |
tmpfs & nbsp; /dev/shm tmpfs defaults 0 0 devpts / dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs Defaults 0 0 proc /proc proc defaults 0 0 /dev/sdb /disk ext3 defaults 0 0 |
