10.5. Configuring manual partitioning

Procedure

1. Select disks for installation:

   1. Click Installation Destination to open the Installation Destination window.
   2. Select the disks that you require for installation by clicking the corresponding icon. A selected disk has a check-mark displayed on it.
   3. Under Storage Configuration, select the Custom radio-button.
   4. Click Done.

2. Detected mount points are listed in the left-hand pane. The mount points are organized by detected operating system installations. As a result, some file systems may be displayed multiple times if a partition is shared among several installations.

   1. Select the mount points in the left pane; the options that can be customized are displayed in the right pane.
   2. Optional: If your system contains existing file systems, ensure that enough space is available for the installation. To remove any partitions, select them in the list and click the - button. The dialog has a check box that you can use to remove all other partitions used by the system to which the deleted partition belongs.

   3. Optional: If there are no existing partitions and you want to create a set of partitions as a starting point, select your preferred partitioning scheme from the left pane (default for Red Hat Enterprise Linux is LVM) and click the Click here to create them automatically link.

      注意

      A /boot partition, a / (root) volume, a swap volume proportional to the size of the available storage and optionally some other partitions, depending on system properties, such as architecture, are created and listed in the left pane. These are the file systems for a typical installation, but you can add additional file systems and mount points.

3. Optional: Continue with adding mount points and configuring the individual mount points.
4. Click Done to confirm any changes and return to the Installation Summary window.

Procedure

1. Click + to create a new file system and related mount point. The Add a New Mount Point dialog opens.
2. Select one of the preset paths from the Mount Point drop-down menu or type your own; for example, select / for the root partition or /boot for the boot partition.

3. Enter the size of the file system into the Desired Capacity field; for example, 2GiB.

   If you do not specify a value in Desired Capacity, or if you specify a size bigger than available space, then all remaining free space is used.

4. Click Add mount point to create the partition and return to the Manual Partitioning window.

Procedure

1. To change the devices that a single non-LVM mount point should be located on, select the required mount point from the left-hand pane.
2. Under the Device(s) heading, click Modify. The Configure Mount Point dialog opens.
3. Select one or more devices and click Select to confirm your selection and return to the Manual Partitioning window.
4. Click Update Settings to apply the changes.
5. In the lower left-hand side of the Manual Partitioning window, click the storage device selected link to open the Selected Disks dialog and review disk information.
6. Optional: Click the Rescan button (circular arrow button) to refresh all local disks and partitions; this is only required after performing advanced partition configuration outside the installation program. Clicking the Rescan Disks button resets all configuration changes made in the installation program.

Procedure

1. From the left pane, select the mount point.

2. From the right-hand pane, you can customize the following options:

   1. Enter the file system mount point into the Mount Point field. For example, if a file system is the root file system, enter /; enter /boot for the /boot file system, and so on. For a swap file system, do not set the mount point as setting the file system type to swap is sufficient.
   2. Enter the size of the file system in the Desired Capacity field. You can use common size units such as KiB or GiB. The default is MiB if you do not set any other unit.

   3. Select the device type that you require from the drop-down Device Type menu: Standard Partition, LVM, or LVM Thin Provisioning.

      注意

      RAID is available only if two or more disks are selected for partitioning. If you choose RAID, you can also set the RAID Level. Similarly, if you select LVM, you can specify the Volume Group.

   4. Select the Encrypt check box to encrypt the partition or volume. You must set a password later in the installation program.

   5. Select the appropriate file system type for this partition or volume from the File system drop-down menu.

      注意

      Support for the VFAT file system is not available for Linux system partitions. For example, /, /var, /usr, and so on.

   6. Select the Reformat check box to format an existing partition, or clear the Reformat check box to retain your data. The newly-created partitions and volumes must be reformatted, and the check box cannot be cleared.
   7. Type a label for the partition in the Label field. Use labels to easily recognize and address individual partitions.
   8. Type a name in the Name field. The standard partitions are named automatically when they are created and you cannot edit the names of standard partitions. For example, you cannot edit the /boot name sda1.
3. Click Update Settings to apply your changes and if required, select another partition to customize. Changes are not applied until you click Begin Installation from the Installation Summary window.
4. Optional: Click Reset All to discard your partition changes.

5. Click Done when you have created and customized all file systems and mount points. If you choose to encrypt a file system, you are prompted to create a passphrase.

   A Summary of Changes dialog box opens, displaying a summary of all storage actions for the installation program.

6. Click Accept Changes to apply the changes and return to the Installation Summary window.

Procedure

1. Click Installation Destination to open the Installation Destination window.
2. Under Storage Configuration, select the Custom radio button. Click Done.
3. Click Done, the Manual Partitioning window opens.

4. Choose the /home partition, fill in /home under Mount Point: and clear the Reformat check box.

   图 10.1. Ensuring that /home is not formatted

   
5. Optional: You can also customize various aspects of the /home partition required for your Red Hat Enterprise Linux 10 system as described in Customizing a mount point file system. However, to preserve /home from your RHEL 9 system, it is necessary to clear the Reformat check box.
6. After you customized all partitions according to your requirements, click Done. The Summary of changes dialog box opens.
7. Verify that the Summary of changes dialog box does not show any change for /home. This means that the /home partition is preserved.
8. Click Accept Changes to apply the changes, and return to the Installation Summary window.

Procedure

1. From the left pane of the Manual Partitioning window, select the required partition.
2. Click the Device Type drop-down menu and select RAID.
3. Under the Device(s) section, click Modify. The Configure Mount Point dialog box opens.
4. Select the disks that you want to include in the RAID device and click Select to close the dialog box.
5. Click the File System drop-down menu and select your preferred file system type.
6. Click the RAID Level drop-down menu and select your preferred level of RAID.
7. Click Update Settings to save your changes.
8. Click Done to apply the settings to return to the Installation Summary window.

Procedure

1. From the Manual Partitioning window, create a new mount point by using any of the following options:

   • Use the Click here to create them automatically option or click the + button.
   • Select Mount Point from the drop-down list or enter manually.

   • Enter the size of the file system in to the Desired Capacity field; for example, 70 GiB for /, 1 GiB for /boot.

     Note: Skip this step to use the existing mount point.

2. Select the mount point.

3. Select LVM in the drop-down menu. The Volume Group drop-down menu is displayed with the newly-created volume group name.

   注意

   You cannot specify the size of the volume group’s physical extents in the configuration dialog. The size is always set to the default value of 4 MiB. If you want to create a volume group with different physical extents, you must create it manually by switching to an interactive shell and by using the vgcreate command, or use a Kickstart file with the volgroup --pesize=size command.

4. Click Done to return to the Installation Summary window.

For more information, see the Automatically installing RHEL document.

5. Optional: From the RAID Level drop-down menu, select the RAID level that you require.

   The available RAID levels are the same as with actual RAID devices.

6. Select the Encrypt check box to mark the volume group for encryption.

7. From the Size policy drop-down menu, select any of the following size policies for the volume group:

   The available policy options are:

   Automatic

   The size of the volume group is set automatically so that it is large enough to contain the configured logical volumes. This is optimal if you do not need free space within the volume group.

   As large as possible

   The volume group is created with maximum size, regardless of the size of the configured logical volumes it contains. This is optimal if you plan to keep most of your data on LVM and later need to increase the size of some existing logical volumes, or if you need to create additional logical volumes within this group.

   Fixed

   You can set an exact size of the volume group. Any configured logical volumes must then fit within this fixed size. This is useful if you know exactly how large you need the volume group to be.

8. Click Save to apply the settings and return to the Manual Partitioning window.
