Cannot create lvol of 2TB

[fsumair_1]

Hi,

I have a system running 11.23 integrity. I have created a vg with extend size of 32MB. And now trying to create a lvol of 1.9GB but it create lvol of only 1 Tb

Is there any patch for this or am i missing something.

Regards
Sam

when you create this vg what is your extent's size?

#vgcreate -e

[Srimalik]

Assuming 19.GB as 1.9TB

AFIK 11.23 does not support logical volumes greater then 2TB in size.

As you are trying to create a 1.9TB volume it should work. Not sure whether a patch is available.

[fsumair_1]

Extent size is 32

[Jeeshan]

what is your "Max PE per PV" value?

[fsumair_1]

It would be default as we did not defined it.. while creating VG

[Jeeshan]

without defining it in large values, its not allowed to create such kind of large lvol.

Sam,

Post the output of "vgdisplay -v" for the volume group in question.

Thanks but I have seen this document before and there is nothing useful that can help me in this situation.

It says the Max Extents per PV default for version 1.0 is 1016, so that's 32 Gb.
You would need 64K to get 2 Tb.
You may want a larger extent size and larger max extents.

Please provide the command you are running for creating LV of 1.9GB

also

vgdisplay -v vgname
