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.
NOTE: Recent patches to mkinitrd might resolve the need to do this task. For the latest version
of mkinitrd, see

You should see the following devices mounted (with your own partition names, of course) for
these two partitions:
/dev/evms/sda1
/dev/evms/sda2
dev/evms path information for the root (/) partition:
/sbin/mkinitrd -f evms
This does not take effect until you restart the server.
Section 2.2.6, "Restart the Server," on page
When your system restarts, the kernel loads the init-ramdisk, which runs the EVMS tools
to activate your volumes and mount your root file system. Then your boot scripts run the
EVMS tools once more to make sure your /dev/evms/ directory correctly reflects the
current state of your volumes. Finally, the remaining EVMS volumes are mounted as specified
in your /etc/fstab file. Everything else on your system should start up as you would
normally expect.
