Disk

The disk page provides disk partition management and LVM logical volume management features.

Disk Management

Disk Information

The top of the page displays basic information for each disk:

• Disk Name: Such as vda, sda
• Type: System disk or data disk
• Size: Total disk capacity
• Partitions: Number of partitions
• Disk Type: HDD, SSD, etc.

Partition List

Each disk shows its partition information:

Column	Description
Partition Name	Partition device name, such as vda1, vda2
Size	Partition capacity
Used	Used space
Available	Available space
Usage	Usage percentage
Mount Point	Mount directory, such as /, /data
File System	File system type, such as ext4, xfs
Actions	Unmount and other operations

Mount Partition

Mount an unmounted partition to a specified directory:

• Partition: Select the partition to mount
• Mount Path: Mount directory, such as /mnt/data
• Mount Options: Mount parameters, such as defaults,noatime
• Auto Mount on Boot: Whether to write to fstab for automatic mounting on boot

Format Partition

Warning

Formatting will erase all data on the partition!

• Partition: Select the partition to format
• File System Type: ext4, xfs, btrfs, etc.

Initialize Disk

Warning

Initialization will delete all partitions and data on the disk!

Initialize the entire disk as a single partition:

• Disk: Select the disk to initialize
• File System Type: ext4, xfs, btrfs, etc.

Auto Mount Configuration (fstab)

Display mount configurations in /etc/fstab:

• Device: Device name or UUID
• Mount Point: Mount directory
• File System: File system type
• Options: Mount options
• Actions: Remove configuration

LVM Management

LVM (Logical Volume Manager) provides flexible disk space management with support for dynamic partition resizing.

Physical Volume (PV)

Physical volumes are the foundation of LVM, typically a disk partition or an entire disk.

Create Physical Volume:

1. Select device (unused partition or disk)
2. Click Create Physical Volume

Volume Group (VG)

A volume group consists of one or more physical volumes, representing a storage pool concept.

Create Volume Group:

1. Enter volume group name
2. Select physical volumes to add
3. Click Create Volume Group

Logical Volume (LV)

Logical volumes allocate space from volume groups, equivalent to traditional partitions.

Create Logical Volume:

1. Enter logical volume name
2. Select volume group
3. Set size (GB)
4. Click Create Logical Volume

Extend Logical Volume

Dynamically extend the size of a logical volume:

1. Select the logical volume to extend
2. Enter extension size (GB)
3. Check Auto Resize File System (recommended)
4. Click Extend Logical Volume

Tip

The advantage of LVM is that logical volumes can be extended online without unmounting partitions or restarting the system.
