Disk
Druid is an interactive program for
editing disk partitions. Users run it only within the Fedora Core
installation system. Disk Druid supports RAID and
LVM to provide more extensible
and reliable data storage.
Figure 6.3.
Disk Setup Screen
Disk Druid displays the following
actions in the installation program:
New
Select this option to add a partition or LVM physical volume to the disk. In the
Add partition dialog, choose a mount
point and a partition type. If you have more than one disk
on the system, choose which disks the partition may inhabit.
Indicate a size in megabytes for the partition.
Illegal Partitions
The /bin/,
/dev/, /etc/,
/lib/, /proc/,
/root/, and
/sbin/ directories may not be used
for separate partitions in Disk
Druid. These directories reside on the
/ (root) partition.
The /boot partition may not reside on
an LVM volume group. Create the
/boot partition before configuring
any volume groups.
You may also choose from three options for sizing your
partition:
Fixed size
Use a fixed size as close to your entry as possible.
Fill all space up to
Grow the partition to a maximum size of your choice.
Fill to maximum allowable
size
Grow the partition until it fills the remainder of the
selected disks.
Partition Sizes
The actual partition on the disk may be slightly smaller
or larger than your choice. Disk geometry issues cause
this effect, not an error or bug.
After you enter the details for your partition, select
OK to continue.
Edit
Select this option to edit an existing partition,
LVM volume group, or an LVM physical volume that
is not yet part of a volume group. To change the size of a
LVM physical volume partition, first remove it from any
volume groups.
Removing LVM Physical Volumes
If you remove an LVM physical volume from a volume group,
you will erase any logical volumes it contains.
Edit a partition to change its size, mount point, or file
system type. Use this function to:
correct a mistake in setting up your partitions
migrate Linux partitions if you are upgrading or
reinstalling Fedora Core
provide a mount point for non-Linux partitions such as
those used on some Windows operating systems
Windows Partitions
You may not label Windows partitions that use the
NTFS file system with a
mount point in the Fedora Core installer. You may label
vfat
(FAT16 or
FAT32)
partitions with a mount point.
If you need to make drastic changes to
your partition configuration, you may want to delete
partitions and start again. If your disk contains data that
you need to keep, back it up before you edit any partitions.
If you edit the size of a partition, you may lose all data
on it.
If your system contains many separate partitions for system
and user data, it is easier to upgrade your system. The
installation program allows you to erase or retain data on
specific partitions. If your user data is on a separate
/home partition, you may
retain that data while erasing system partitions such as
/boot.
Delete
Select this option to erase an existing partition
or LVM physical volume. To delete an LVM
physical volume, first delete any volume groups of which
that physical volume is a member.
If you make a mistake, use the Reset
option to abandon all the changes you have made.
Reset
Select this option to force Disk
Druid to abandon all changes made to disk
partitions.
RAID
Select this button to set up software RAID on your Fedora system.
Create a software RAID
partition
Choose this option to add a partition for software
RAID. This option is the only choice available if
your disk contains no software RAID partitions.
Create a RAID device
Choose this option to construct a RAID device from two
or more existing software RAID partitions. This
option is available if two or more software RAID
partitions have been configured.
Clone a drive to create a RAID
device
Choose this option to set up a RAID
mirror of an existing disk.
This option is available if two or more disks are
attached to the system.
LVM
Select this button to set up LVM on your Fedora system. First create at least one
partition or software RAID device as an LVM physical volume,
using the New dialog.
To assign one or more physical volumes to a volume group,
first name the volume group. Then select the physical
volumes to be used in the volume group. Finally, configure
logical volumes on any volume groups using the
Add, Edit and
Delete options.
You may not remove a physical volume from a volume group if
doing so would leave insufficient space for that group's
logical volumes. For example, if a volume group is made up
of two 5 GB LVM physical volume partitions, then it contains
an 8 GB logical volume. The installer would not allow you
to remove either of the component physical volumes, since
that would leave only 5 GB in the group for an 8 GB logical
volume. If you reduce the total size of any logical volumes
appropriately, you may then remove a physical volume from
the volume group. In the example, reducing the size of the
logical volume to 4 GB would allow you to remove one of the
5 GB physical volumes.
After you finish setting up and reviewing your partition
configuration, select Next to continue the
installation process.
