# 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

::: danger Warning
|
|
Formatting will erase all data on the partition!
|
|
:::
|
|
|
|
- **Partition**: Select the partition to format
|
|
- **File System Type**: ext4, xfs, btrfs, etc.
|
|
|
|
### Initialize Disk
|
|
|
|
::: danger 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`:
|
|
|

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