to
/dev/evms/ sda2
Replace
sda2
with the actual device on your machine.
3c Edit any device paths in the Other Kernel Parameters field.
3d Click OK to save the changes and return to the Boot Loader page.
4 Modify the failsafe image so that the failsafe root file system is mounted as
/dev/evms/
instead of
/dev/
.
4a Select the failsafe image file, then click Edit .
4b
Edit the device path in the Root Device field.
4c Check the Other Kernel Parameters field and make changes if needed.
4d
Click OK to save the change and return to the Boot Loader page.
5 Click Finish .
6 Continue with Section 2.2.5, “Force the RAM Disk to Recognize the Root Partition,” on
page 25 .
Using a Text Editor
To edit the boot loader file in a text editor:
1 Log in as the
root
user or equivalent.
2 Open the boot loader file in a text editor.
For Grub, this is the
/boot/grub/menu.1st
file. For LILO, this is the
/etc/lilo.conf
file.
3 Locate the line that contains the
root=
parameter.
For example, if your root file system uses device sda1, look for a line similar to this:
kernel (sd0,0)/vmlinuz root=/dev/sda1 vga=0x31a splash=silent showopts
4
Modify the mount location from
/dev
to
/dev/evms
so it can be managed by EVMS.
For example, after the change, the line looks like this:
kernel (sd0,0)/vmlinuz root=/dev/evms/sda1 vga=0x31a splash=silent
showopts
5 Repeat Step 3 and Step 4 to locate other lines in the file that need to be similarly modified.
6 Save the file.
The changes do not take effect until the server is restarted. Do not restart at this time.
7 Continue with Section 2.2.5, “Force the RAM Disk to Recognize the Root Partition,” on
page 25 .
2.2.5 Force the RAM Disk to Recognize the Root Partition
The mkinitrd(8)
command creates file system images for use as initial RAM disk (initrd) images.
These RAM disk images are often used to preload the block device modules (SCSI or RAID) needed
to access the root file system.
You might need to force the RAM to update its device node information so that it loads the root (
/
)
partition from the
/dev/evms
path.
