Cannot create a Physcial volume by use ScaleIO volume

In order to add ScaleIO volumes as PVs you need to add the block type to the allowed types for LVM.

For centOS 7 (and possibly others)

1) Open /etc/lvm/lvm.conf

2) Add the line

types = [ "scini", 252 ]

below

# List of pairs of additional acceptable block device types found     # in /proc/devices with maximum (non-zero) number of partitions.     # types = [ "fd", 16 ]

3) Then go through the normal process of adding PV to a VG

(Refer to pages 316-317 of the ScaleIO User Manual)

I will warn you, that the OS does have to be booted and connected to the network in order for you to be able to mount the full LV. If you extend the root volume with a ScaleIO volume, you will not be able to boot anymore.

Thanks, It works.But if I reboot the machine, the Volume Group created by using ScaleIO volume are gone, disappear.I can found in /dev/.

I add the following line to the /etc/fstab file:

/dev/vg_sio/lv_sio      /mnt/sio                ext4            _netdev         0 0

And the system boot up print message

And I just not add the volume to PV , only mount the volume ! Here also has problem.

Am I lost some settings?I just follow the User Guide.
