16.9. Formatting RAID in the web console

You can format and mount software RAID devices in the RHEL 10 web console.

Formatting can take several minutes depending on the volume size and which formatting options are selected.

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.
You have connected physical disks and they are visible by the system.
You have created RAID.

Procedure

Log in to the RHEL 10 web console.
In the panel, click Storage.
In the Storage table, click the menu button ⋮ for the RAID device that you want to format.
From the drop-down menu, select Format.
In the Format field, enter a name.
In the Mount Point field, add the mount path.
From the Type drop-down list, select the type of file system.
Optional: Check the Overwrite existing data with zeros option, if the disk includes any sensitive data and you want to overwrite them. Otherwise the RHEL web console rewrites only the disk header.
In the Encryption drop-down menu, select the type of encryption. If you do not want to encrypt the volume, select No encryption.
In the At boot drop-down menu, select when you want to mount the volume.
In the Mount options section:
1. If you want to mount the volume as a read-only logical volume, select the Mount read only checkbox.
2. If you want to change the default mount option, select the Custom mount options checkbox and add the mount options.
Format the RAID partition:
- If you want to format and mount the partition, click the Format and mount button.
- If you want to only format the partition, click the Format only button.

Verification

After the formatting has completed successfully, you can see the details of the formatted logical volume in the Storage table on the Storage page.
