Free PE / Size 2124556 / 8.10 TB

6 Create a new logical volume on “vg00”, using the following command:

lvcreate -l <Free_PE_value>-i <#_of_physical_volumes> -I 32

-n lvol1 vg00

where <Free_PE_value> is the “Free PE” value you noted in the

preceding step and <#_of_physical_volumes> is the number of

physical volumes. If we continue with the example used in the previous

steps, you would type:

lvcreate -l 2124556 -i 4 -I 32 -n lvol1 vg00

The output confirms the creation of the logical volume:

Logical volume “lvol1” created

NOTE If the command outputs several lines about a file descriptor leaked

on lvdisplay invocation, ignore them.

7 Check if the adsk_lvm startup script has been installed by the DKU to

enable automatic logical volume reassembly upon reboot:

chkconfig --list | grep adsk_lvm

If the script is properly configured, the command output is the following:

adsk_lvm 0:off 1:off 2:on 3:on 4:on 5:on 6:off

If the command output is different, enable the script by typing:

chkconfig --add adsk_lvm

chkconfig adsk_lvm on

Creating the XFS Filesystem on the Logical

Volume

After having created the logical volume, you are now ready to create and

mount the XFS filesystem.

To create and mount an XFS filesystem:

1 Identify the optimal agsize value for your array by running the mkfs.xfs

command. Type:

mkfs.xfs -d agcount=128 -f /dev/vg00/lvol1

This command displays diagnostics information similar to the following

(your values may differ):
