12 Type w to save the new partition table.
13 Repeat steps 2 through 9 for each disk or LUN device identified in step
1.
Assembling the Disk or LUN Devices into a Lo-
gical Volume
After you have formatted each disk or LUN device as a partition, you must
assemble the LUNs into a single logical volume on which you create the XFS
filesystem.
This procedure does not cover creating fault-tolerance and assumes that the
LUNs are RAID-protected, as is the case with Stone Direct XR-series arrays.
To assemble a logical volume:
1 Verify that the disk or LUN devices are detected by the operating system.
Type:
fdisk -l | grep dev
All devices appear in a list similar to the following example (your values
may vary):
/dev/sdb1 1 180482 1449713663+ ee EFI GPT
/dev/sdc1 1 180482 1449713663+ ee EFI GPT
/dev/sdd1 1 180482 1449713663+ ee EFI GPT
/dev/sde1 1 180482 1449713663+ ee EFI GPT
Partitions created with the parted command for arrays with 450 GB disks
are marked “EFI GPT”.
Partitions created in fdisk for arrays with smaller capacity disks are marked
“Linux LVM”.
NOTE Other devices of different types may be listed before and after the
GPT or LVM devices.
2 Create a physical volume on each of the devices using the following
command:
pvcreate<list of devices>
where <list of devices> is a list of all the devices in the storage
array. For example, if you have four devices, ranging from /dev/sdb1 to
/dev/sde1, you would type:
