3.7. Formatting LVM-VDO volumes in the web console

LVM-VDO volumes act as physical drives. To use them, you must format them with a file system.

警告

Formatting erases all data on the volume. Creating a file system might take a long time.

Prerequisites

You have installed the RHEL 10 web console.
For instructions, see Installing and enabling the web console.
You have installed the cockpit-storaged package on your system.
You have created an LVM-VDO volume.

Procedure

Log in to the RHEL 10 web console.
In the panel, click Storage.
Click the LVM2 volume group that has the LVM-VDO volume you want to format and click the menu button [⋮] for the LVM-VDO volume.
In the drop-down menu, click Format.
In the Name field, enter the logical volume name.
In the Mount Point field, enter the mount path.
From the Type drop-down list, select a file system.
Optional: Select Overwrite existing data with zeros, if the disk includes any sensitive data and you want to rewrite them. Otherwise the web console rewrites only the disk header.
From the Encryption drop-down list, select the type of encryption.
From the At boot drop-down list, select when you want to mount the volume.
In the Mount options list, choose the appropriate settings:
1. Select the Mount read only checkbox if you want to mount the volume as a read-only logical volume.
2. Select the Custom mount options checkbox and add the mount options if you want to change the default mount option.
Format the LVM-VDO volume:
1. If you want to format and mount the LVM-VDO volume, click Format and mount.
2. If you want to only format the partition, click Format only.

Verification

Verify the details of the formatted LVM-VDO volume on the Storage tab and in the LVM2 volume group tab.
