Maximum LE per lvol is 65335 (not sure about the exact number, but around that), which means in you case with a PE size of 4MB you cannot extend it to more then ~ 255 GB.

Which LV here did you try to extend ? and what was your command to do ?

[itrc55]

Hi,

And what is the solution now ?
OS is 11.31

Thanks

[itrc55]

Hi,

lvextend -L 307141 /dev/oravg/date01_lv
Warning: rounding down logical volume size to extent boundary at size "307140" MB.

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

Hi,

sorry - wrong idea - I delete my reply.

But Stephan seems to be right - you only can extend till 65335 * 4 MB = 261340 MB = 255 GB

V.

[Hakki Aydin Ucar]

You used more than max. LV value ine totally, and need to try smaller value

"307140" MB. > Mx. LV

OR you have to change Max. LV .

[itrc55]

Hi,

i tray with below this value bu is the same issue

lvextend -L 276480 /dev/oravg/date01_lv
lvextend: "LogicalExtentsNumber" is bigger than the maximum value allowed.

How to change Max. LV

Thanks

[V. Nyga]

276480 is not below 261340 ;-)

[V. Nyga]

From lvcreate (from HP-UX 11.11):
Option -l : Allocate space to the log. vol. specified in logical extends. Range 1 to 65535 (the implementaion limit) ....

So 65535 * 4 MB = 262140 MB as maximum.

From Option -L : ... allocated space in megabytes.
... range from 1 to 16777216 (the implementaion limit) ....

So maybe only changeable with the value of PE size ....(in Kernel?)

[itrc55]

Hi,

i increase the lvol to max size, becuase when i try to extend the lvol with 1 GB i facing the same error.

is there any way to change PE size from 4 MB to 16 MB for example.

my OS is 11.31

Thanks

[Stephan.]

There is no way to change the PE size as far as I know.

Backup, recreate vg with new parameters, restore would be my only solution.

Sorry to say ..

Best,

Stephan

Hi,

Looks confusing, which lv did you want to extend and what command do you perform.

Hi All,

thanks for your support, but the last question how to change this value Max_PE_per_PV by using vgmodify on 11.31. if i facing this issue on future

Thanks

[Hakki Aydin Ucar]

It cannot be changed unless the volume group is recreated from scratch as others said.

Hi,

how to check VG version? and is there any solution if i change the VG to other version ? and if there any solutions except
backup - remove Vg - create VG - restore

Thanks

[Torsten.]

>> how to check VG version?

It is in your vgdisplay output:

VG Version                  1.0

[itrc55]

Hi,

thanks for you replay, my VG version is 1.0 if i convert it to version 2.2, Is there any benefit from that to resolve my problem.

Thanks
