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

Hi,

I am getting following errors while trying to extend lvol.

Anyone please let me the possible cause for the same?

IMHO there is no doubt about this "problem".

Your command lines are not visible.

Hi,

Can we change the PE size online? Its 11v3 and VG ver1.0

I believe if i will change the PE size from 16 MB to 32 MB then i would be able to extend the LVOL as for 11v3 the max PE for lvol is 65535.

My confusion is that can we change the PE size of a vg? and steps to change the VG?

[Patrick Wallek]

No, the PE Size for a VG cannot be changed once the VG has been created.

The things that can be changed, via the 'vgmodify' command are:

Max PE per PV

Max Number of LVs in the VG

Max Number of PVs in the VG

HI,   On VG ver 1.0 Logical volume extend max size  is limited to

Maximum number of logical extents per logical volume 65535 * PE size
