The “vgcreate” command is a Linux system administration utility that is used to create volume groups (VGs) on a Linux system. Volume groups are a logical collection of one or more physical volumes (PVs), such as hard disks, partitions or RAID arrays. By grouping physical volumes into a volume group, you can create a single virtual pool of storage that can be used to create logical volumes (LVs) which can be used to store data.
If you encounter the below error while running the command vgcreate:
vgcreate: command not found
you may try installing the below package as per your choice of distribution:
| Distribution | Command |
|---|---|
| Debian | apt-get install lvm2 |
| Ubuntu | apt-get install lvm2 |
| Alpine | apk add lvm2 |
| Arch Linux | pacman -S lvm2 |
| Kali Linux | apt-get install lvm2 |
| CentOS | yum install lvm2 |
| Fedora | dnf install lvm2 |
| Raspbian | apt-get install lvm2 |
vgcreate Command Examples
1. Create a new volume group called vg1 using the `/dev/sda1` device:
# vgcreate vg1 /dev/sda1
2. Create a new volume group called vg1 using multiple devices:
# vgcreate vg1 /dev/sda1 /dev/sdb1 /dev/sdc1
Summary
After the volume group has been created, you can create logical volumes within it using the “lvcreate” command. You can also resize, rename, and remove volume groups using the “vgresize”, “vgrename”, and “vgremove” commands, respectively.
Overall, the “vgcreate” command is a powerful tool for managing storage on Linux systems. It allows you to create a single virtual pool of storage that can be used to create logical volumes, which can be used to store data for a wide range of applications and use cases.
