LogicalExtentsNumber is bigger than the max value allowed

[Popy]

Hi all,

I am trying to extend a LV to 275 GB but its allowing me only upto 265 GB. I have 1300 PEs(of 4 MB) free in that VG.
when I give,

lvextend -L 275000 /dev/vgdev04/lvol1

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

here is the Vgdisplay output...
--- Volume groups ---
VG Name /dev/vgdev04

Hi,

I think you have no enough PE free

1300 PE x 4 = 5200 MB free

What is the current size off /dev/vg04/lvol1

lvdisplay /dev/vg04/lvol1

Well - 275000 is NOT equal to 275GB...

1381 * 4 = 5524MB

Max is: 66881 * 4 = 267524

So, try lvextend -L 267524 /dev/vgdev04/lvol1

There is a limit of 65535 LE's. With your 4MB LE's, that is about 260000 and you're asking for 275000. You could use the -l option and specify 65535.

Hi:

Yes, you have tried to use more than 65,535 logical extents -- the limit for a logical volume.

Your only choice is to recreate the *volume group* ('vgcreate') and specify a larger extent size ('-s pe_size'). The default pe_size of four (4) is small for today's disks and file systems.

Regards!
