lvextend: "LogicalExtentsNumber" is bigger than the maximum value allowed.

Problem :

testnodep-root> lvextend -L 2097152 /dev/vg_wasdb_01/lv_data01 lvextend: "LogicalExtentsNumber" is bigger than the maximum value allowed.

In HP UNIX LVM, Logical Volume of maximum size would be created of LE = 65535

With PE Size of 32MB we can create logical volume of maximum size of 1.999969482421875 TB.

Now LV Size = (LV Size) 2097120 % PE Size (32) = 65535 (LE) which is max size logical volume we can create.

Solution:

If we recreate the Vg with PE SIZE more than 32, the above problem can be resolved

Suppose for example if we are creating Vg with PE size 128:

Now (LV Size) 2097120 % PE Size (128) = 16383.75, which is not reaching to the max size logical volume we can create.

With PE Size of 128MB we can create logical volume of maximum size of 7.9998779296875 TB
