If you do not configure the device to use EVMS, you must manage the device and all of its volumes
with its current volume manager (the default is LVM), and free space on the device cannot be used
for volumes you want to create using EVMS. Beginning with the Linux 2.6 kernel, any given device
cannot be managed by multiple volume managers. However, you can have different volume
managers for different devices.
The following procedures assume that you installed Linux with three partitions on a single SCSI
device named
sda
:
/dev/sda1 reiserfs /boot
/dev/sda2 swap swap
/dev/sda3 reiserfs /
IMPORTANT:
Make sure to modify the following procedures as necessary for your specific setup.
Section 2.2.1, “Disable the boot.lvm and boot.md Services,” on page 22
Section 2.2.2, “Enable the boot.evms Service,” on page 22
Section 2.2.3, “Edit the /etc/fstab File,” on page 23
Section 2.2.4, “Edit the Boot Loader File,” on page 24
Section 2.2.5, “Force the RAM Disk to Recognize the Root Partition,” on page 25
Section 2.2.6, “Reboot the Server,” on page 26
Section 2.2.7, “Verify that EVMS Manages the Boot, Swap, and Root Partitions,” on page 26
2.2.1 Disable the boot.lvm and boot.md Services
You need to disable
boot.lvm
(handles devices for Linux Volume Manager) and
boot.md
(handles multiple devices in software RAIDs) so they do not run at boot time. In the future, you
want
boot.evms
to run at boot time instead.
