Resizing Disk Space in Ubuntu Server v16.04.2 at VMware ESXi v6 Virtual Environment 【中文】

【Problem】VM client's disk space is almost full, we must resize it.
【Solution】

• VMware

1. shutdown VM client
2. Configuration >> Hard Disk 1 >> Disk Provisioning >> Provisioned Size >> enlarge
3. start up VM client

• use PuTTY/SSH connect to VM client

• list all disk partitions

• ls -al /dev/sda*

• create a new disk partition






sudo fdisk /dev/sda

• p >> show all partitions
• n >> create a new partition
• p >> select a physical partition
• 3 >> create /dev/sda3
• enter >> input start sector address
• enter >> input end sector address
• t >> transfer partition format into Linux LVM
• 8e >> select partition format as Linux LVM
• p  >> show all partition
• w >> execute partition process and then exit

• reboot system






sudo reboot --r 0

• create physical volume






sudo pvcreate /dev/sda3

• extend current Volume Group to physical volume, show VG Name, find Volume Group and VG Name, VG Name = Volume Group Name






sudo vgdisplay






sudo vgextend  ApaMoodle-pv /dev/sda3

• extend primary Logical Volume, find LV Name, such as /dev/ApaMoodle-pv/root. Then extend the Logical Volume size (GBs).






sudo lvdisplay






sudo lvextend -L +250G  /dev/ApaMoodle-pv/root

• adjust file system to latest allocated space






sudo resize2fs /dev/ApaMoodle-pv/root
