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:
