2.2.6 Reboot the Server
1
Reboot the server to apply the post-install configuration settings.
When your system reboots, 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.
2 Continue with Section 2.2.7, “Verify that EVMS Manages the Boot, Swap, and Root
Partitions,” on page 26 .
2.2.7 Verify that EVMS Manages the Boot, Swap, and Root
Partitions
1
At a terminal prompt, enter the EVMS Ncurses command as the
root
user or equivalent:
evmsn
2 Review the output to verify that EVMS shows the
/boot
,
swap
, and root (
/
) partitions as
active in EVMS.
You should see the following devices mounted (with your own partition names, of course)
under the
/dev/evms
directory:
/dev/evms/sda1
/dev/evms/sda2
/dev/evms/sda3
2.3 Configuring LVM Devices After Install to Use
EVMS
Use the following procedure to configure data devices (not system devices) to be managed by
EVMS. If you need to configure an existing system device for EVMS, see
Section 2.2, “Configuring
an Existing System Device to Use EVMS,” on page 21 .
1 In a terminal console, run the EVMSGUI by entering the following as the
root
user or
equivalent:
evmsgui
2 In the Volumes panel, review the names that EVMS reports as compatibility volumes, find the
devices that represent the devices you want to manage using EVMS, then write down the
names for future reference.
For example,
/dev/sdb1
.
3 In a text editor, edit the
/etc/fstab
file to use the EVMS volume names.
For example, change the following entry for an LVM2 volume from this
/dev/sdb1 / reiserfs defaults 1 2
to this
/dev/evms/lvm2/sdb1 / reiserfs defaults 1 2
IMPORTANT: Make sure not to leave any stray characters or spaces in the line.
