Linux Server disk expansion method (figure) _linux

1, the system environment as follows:

2, for the system to add a new virtual hard disk, add the need to restart the virtual machine, otherwise the system is not recognized; The following figure,/DEV/SDC is a newly added hard disk;


3. FDISK/DEV/SDC create partitions for new hard drives:


4, Linux allows a primary partition of 4, then we create partitions for/DEV/SDC1
5, by default, the new partition format for Linux, we use LVM dynamic add disk space, it is necessary to modify the/DEV/SDC1 partition format LVM,LVM format ID 8e;
6, create and modify the success of the need to format the partition: MKFS.EXT3/DEV/SDC1
7, execution completed into the/ETC directory to see if there is a SDC1 folder, if it does not exist, then execute the command partprobe, and then execute the format command;
8, add new LVM to existing LVM group, to achieve expansion:
(1) LVM into LVM management
(2) LVM>PVCREATE/DEV/SDC1 initialization partition
(3) Lvm>vgextend VOLGROUP00/DEV/SDC1 the initialized partition into the virtual volume group Volgroup00-logvol00
(4) Lvm>lvextend-l +5g/dev/mapper/volgroup00-logvol00 expands the capacity of existing volumes
(5) Lvm>pvdisplay View volume capacity
(6) Lvm>quit
9, expansion of the file system: Resize2fs/dev/mapper/volgroup00-logvol00
