Make sure to replace sda1 , sda2 , and sda3 with the device names you used for your partitions.
IMPORTANT: When working in the
/etc/fstab
file, do not leave any stray characters or
spaces in the file. This is a configuration file, and it is highly sensitive to such mistakes.
1 Open the
/etc/fstab
file in a text editor.
2 Locate the line that contains the
/boot
partition.
For example, if your
/boot
partition uses device sda1 and the Reiser file system, look for a
line similar to this:
/dev/ sda1 /boot reiser defaults 1 1
3 In the Device Name column, modify the mount location of the
/boot
partition from
/dev
to
/dev/evms
so it can be managed by EVMS. Modify only the device name by adding
/evms
to the path:
/dev/evms/ sda1 /boot reiser defaults 1 1
4
Repeat Step 2 and Step 3 to edit the Device Name entry in the lines for the
swap
and root (
/
)
partitions.
For example, change
/dev/ sda2
to
/dev/evms/ sda2
, and change
/dev/ sda3
to
/
dev/evms/ sda3
.
5 Save the file.
The changes do not take effect until the server is restarted. Do not restart at this time.
6 Continue with Section 2.2.4, “Edit the Boot Loader File,” on page 24 .
2.2.4 Edit the Boot Loader File
When you boot the system, the kernel reads the boot loader file for information about your system.
For Grub, this is the
/boot/grub/menu.1st
file. For LILO, this is the
/etc/lilo.conf
file.
You must edit the boot loader file to modify the mount location of partitions so they are mounted
under the
/dev/evms
directory. For example, change /dev/ sda1 to /dev/evms/ sda1 . Make sure to
replace the path for all lines that contain device paths in the files. You can modify the boot loader
file by editing fields in YaST, or use a text editor to modify the file directly.
IMPORTANT: When working in the boot loader file, do not leave any stray characters or spaces in
the file. This is a configuration file, and it is highly sensitive to such mistakes.
Using YaST
To modify the boot loader file in the YaST Control Center:
1 Log in as the
root
user or equivalent.
2 In Yast, select System > Boot Loader .
3 Modify the boot loader image so that the root file system is mounted as
/dev/evms/
instead
of
/dev/
.
3a Select the boot loader image file, then click Edit .
3b Edit the device path in the Root Device field.
