# CentOS ### CentOS-8 - 20200528 * A volume group named `rootvg` includes the base `/dev/vda` disk. * `/dev/vdb` is mounted by default to `/data` but can be added to `rootvg` so you can extend `rootlv` (the / mount point) as necessary. * A base 15GB of storage is allocated to the OS volume (rootvg) in addition to the `/data` storage. ### CentOS-7 - 20200528 * A volume group named `rootvg` includes the base `/dev/vda` disk. * `/dev/vdb` is mounted by default to `/data` but can be added to `rootvg` so you can extend `rootlv` (the / mount point) as necessary. * A base 15GB of storage is allocated to the OS volume (rootvg) in addition to the `/data` storage. ### CentOS-7-cPanel - 20200528 * A volume group named `rootvg` includes the base `/dev/vda` disk. * `/dev/vdb` is mounted by default to `/data` but can be added to `rootvg` so you can extend `rootlv` (the / mount point) as necessary. * A base 15GB of storage is allocated to the OS volume (rootvg) in addition to the `/data` storage. * The filesystem layout is well suited for cPanel as it includes the following base mount points as logical volumes: * `/`, `/usr`, `/var`, and `/home` which can all be extended because they are part of the `rootvg` volume group. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
