Cloud Server Linux re-mount the specified directory (non-expandable)

The new Hong Kong cloud server, the system can only be installed on the merchant's console.

The system is separate from the hard drive, and the root directory space is only 10G. Need to reset the relevant directory size, such as:/usr,/var,/home and so on.

The following is a subtotal of your own workaround.

First, the initial partition situation (plus a 300G unpartitioned hard disk):

[[email protected] ~]# df-th file system    type      capacity  used with  available percent mount point/dev/mapper/vg_cloud-lv_root              ext4     8.1G   484M   7.2G   7%/tmpfs        tmpfs     2.0G    91k   2.0G   1%/dev/shm/dev/sda1     ext4     508M    51M   431M  11%/boot

[Email protected] ~]# Fdisk-l | lessdisk/dev/sdb:311.4 GB, 311385128960 bytes255 heads, sectors/track, 37857 cylindersunits = cylinders of 16065 * 51 2 = 8225280 bytessector size (logical/physical): bytes/512 bytesi/o size (minimum/optimal): bytes/512 bytesDis K Identifier:0x0473169adevice Boot Start End Blocks Id System

Second, partition the hard disk, format, and mount to the/mnt/disk300g node.

[Email protected] ~]# fdisk/dev/sdb    #分区的时候之分一个区/dev/sdb1[[email protected] ~]# mkfs.ext4/dev/sdb1    #格式化分区, Note Your system's file format (ext2, ext3, EXT4), which you can view with df-th. [[email protected] ~]# mkdir/mnt/disk300g && mount-t ext4/dev/sdb1/mnt/disk300g    # mount to node/mnt/dis300g[[emai L protected] ~]# df-th file system    type      capacity  used with  available percent mount point/dev/mapper/vg_cloud-lv_root              ext4     8.1G   484M   7.2G   7%/tmpfs        tmpfs     2.0G    91k   2.0G   1%/dev/shm/dev/sda1     ext4     508M    51M   431M  11%/boot<span style= "color: #cc0000; Background-color:rgb (255, 255, 255);" >/DEV/SDB1     ext4     307G   3.3G   288G   2%/mnt/disk300g</span>

third, the replication root directory needs to be reset the size of the directory node under/mnt/disk300g, the following are/usr,/var,/home for example.

[[email protected] ~]# cp-av/usr/var/home/mnt/disk300g/[[email protected] ~]# ll/mnt/disk300g/total usage 28drwxr-xr-x.  2 root root  4096 September  homedrwx------.  2 root root 16384 May  16:38 lost+founddrwxr-xr-x root root  4096 September   9 usrdrwxr-xr-x. Root Root
   4096 September   9 var

backup/usr,/var,/home directory, and mount the relevant directory under/mnt/disk300g/to the root directory.

You should then be able to see the contents of/usr,/var, and/home as before the backup.

V. Boot/restart auto mount (equivalent to step four operation).
