Linux system disk Mount information file

Set File system mount information (Etc/fstab) so that the boot can automatically mount the disk partition

File System mount

Method One: Directly hanging in, temporary effect

# format System (no file system without formatting, no data)    DD If=/dev/zero of=/dev/sdb1 bs=4096 count=10   --Create a virtual block device-file system    MKFS.EXT4/ DEV/SDB1    --format    mount-t ext4-o loop,noexec,noatime/dev/sdb1/mnt    --Mount    df-h  View Portal

Method Two: Edit configuration, Permanent effect

# 2-1-1  Edit configuration file

    Vim/etc/fstab      # Assume the following configuration:
Dev/mapper/volgroup-lv_root     /   ext4 (EXT2,PROC,XFS,TMPFS, etc.)   defaults   1           1 first column: device/information to be hung (UUID, Label disk partition) The second column: The point at which the disk is to be hung the third column: The file system to which to mount the fourth column: Mount option (read-only, write-only, etc.) column fifth: whether to back up (0 not backup, 1 backup) column sixth: If the system fails scan recovery, set parameter 1, no set 0              

# 2-1-2 Reload     mount-a# 2-1-3 df-h  View Portal

Method Three: Write the self-boot file, permanent effect

# Edit the profile file to start the disk    vim/etc/rc.local

        Mount-t ext4-o loop,noexec,noatime/dev/sdb1/mnt    # Write Mount

System Mounting considerations

Note The fstab file configuration error will cause the file system to not come up and can be rescued as follows
0 Modify/etc/fstab, but the files are read-only and need to be changed
Mount-o Rw,remount/
1 boot will not start after the prompt, enter the password, repair
2 Rescue Mode: Rescue
