Llinux system (Centos/Ubuntu/Debian) elastic cloud data disk home expansion | cloud disk one-click partition expansion

For Windows data disk expansion, please refer to: https://www.west.cn/faq/list.asp?unid=512 For Windows system, please refer to: https://www.west.cn/faq/list.asp?unid=2220 For Linux system disk, please refer to: https://www.west.cn/faq/list.asp?unid=905 I. Automatic Processing by Script Applicable to: data disk home partition upgrade, expansion, and merge; cloud disk (https://www.west.cn/faq/list.asp?unid=2249) upgrade, expansion, and merge. (Note: Do not execute in the 宝塔面板 terminal.) Enter the following command to execute: wget -O homeV31.sh http://downinfo.myhostadmin.net/vps/homeV31.sh && bash homeV31.sh && rm -rf homeV31.sh For data disk home upgrade, expansion, and merge, just press Enter or enter /dev/vdb. For cloud disk (https://www.west.cn/faq/list.asp?unid=2249) upgrade, expansion, and merge, you need to enter the specific disk name. If one cloud disk is mounted, the default disk name is /dev/vdc, and the default partition name is /dev/vdc1. If two are mounted, there will be an additional /dev/vdd (partition name /dev/vdd1). If an error occurs during execution, please check whether the disk name to be merged is correct. During execution, an error pause may pop up. If this prompt appears, enter Ignore. II. Manual Processing Method: The following is the procedure for adding a home partition on a Linux server. If you need to increase the size of the home partition after upgrading a VPS or cloud host, you can increase it by this method. Special reminder: After deleting a partition, you must create the partition first and then save. Clicking save after deletion will cause data loss. If you are not familiar with Linux, it is recommended to submit a maintenance ticket and our company will handle it manually, with a fee of 100 yuan. This operation is risky. To avoid data loss caused by misoperation, please back up your important data before operation! If it is a cloud disk upgrade and expansion, please note that /dev/vdb in the following command lines should be replaced with the actual disk name. For one mounted cloud disk, the default disk name is /dev/vdc, and the default partition name is /dev/vdc1. Notes: Gray content is displayed by the Linux system. Red content is the entered command. //Green content is the explanation of commands or displayed content. [root@west5066 ~]# df -vh //Check the disk name where the home partition is located. Our company generally uses vdb; the default name of a mounted cloud disk is generally vdc.

Use vi /etc/fstab to edit the partition table file, comment out the home partition, restart the server, and then proceed to the next step. //After restarting, you can mount /dev/vdb1 /home, then download and run the sh script. After completion, uncomment the partition table, restart the server to complete the expansion! [root@west5066 ~]# parted /dev/vdb // /dev/vdb here is the disk name. If this program is not available, run yum install parted to install it! If it is cloud disk expansion, the name defaults to /dev/vdc. GNU Parted 2.1 Using /dev/vda1 Welcome to GNU Parted!
