The machine is mounted on two hard drive items have files to be written in the Mount directory, so need to boot mount, Google a bit, the original is easy AH
Refer to this article
When using multiple solid-state drives on a Linux system, by default only mount the system disk, to use the other disk, we need to mount the hard drive, the following is a brief introduction, I am on the new hard disk operation method.
To view a hard drive in the system that is not mounted
sudo hdparm-i/dev/sdb hard disk hardware installation, this command tests whether the Linux system can find the mounted unpartitioned hard drive.
Since we do not need partitions here, we do not have to partition the operation.
Format the hard drive
Use the command sudo mkfs-t ext3/dev/sdb1/dev/sdb1 as a descriptor for the new hard drive on Linux. The new hard disk partition created above is formatted into EXT3 format, which will wait for a while to end automatically.
Set the volume label for a new hard disk
sudo e2label/dev/sdb1/code/code is the name under the root directory of the/DEV/SDB1 new hard drive
Set mount point
sudo mkdir/code//Create mount point under root path
Set up automatic mount
Use the command sudo vim/etc/fstab to edit the file, and the file's configuration list is as follows:
File system mount point type options Dump Pass
A b c d E F
A refers to the device name of the file system. Initially, the field contains only the device names (such as/DEV/SDA1) for the partition to be mounted. Now, in addition to the device name, you can include a label or UUID
B file System mount point. The file system contains all the data in the entire directory tree structure under the mount point, unless one of the directories mounts another file system
C file system type. The following are the most common file system types (EXT3,TMPFS,DEVPTS,SYSFS,PROC,SWAP,VFAT)
D mount command options. The Mount option includes Noauto (which does not mount the file system on startup) and RO (read-only mount file system), and so on. Add a user or Owner option to this field to allow the user to mount the file system. Multiple options must be separated by commas. Information about other options is available in the Mount Command man page (---o option)
E dump file system. This field only makes sense when you are backing up with a dump. The number 1 indicates that the file system requires a dump, and 0 does not need to dump the
F file system check. The number in the field indicates whether the file system needs to be checked with fsck. 0 means that the file system does not have to be checked, and the number 1 indicates that the filesystem needs to be checked in advance (for the root file system). The number 2 indicates that after the root file system check is completed, the file system is checked again
we need to write the configuration to the file in the format above, note that each tab is used to separate each other, our configuration information is as follows:
/dev/sdb1/code ext3 defaults 1 2/DEV/SDB1 The identifier for the hard disk
and then remember to save the file.
Reboot to see if mount successful
use the df-h command to view the partition space usage, and you can see that the/code is automatically mounted. The results of the view are as follows:
FileSystem Size Used Avail use% mounted on
/DEV/SDA1 139G 121G 12G 92%/
Varrun 1.3G 68K 1.3G 1%/var/run
Varlock 1.3G 0 1.3G 0%/var/lock
Udev 1.3G 32K 1.3G 1%/dev
Devshm 1.3G 0 1.3G 0%/dev/shm
/DEV/SDB1 924G 11G 867G 2%/code
Seeing our/code is already on the top, it's done.

adds the following Line Note tab-separated
/dev/sda1 /data ext3 defaults 1 2
/dev/sdb1 /backup ext3 defaults 1 2

Set the volume label for a new hard disk
E2label /dev/sda1 /data
e2label /dev/sdb1 /backup
Sudo e2label/dev/sda1/data/data is the name of the/dev/sda1 new hard drive root directory
