Re: Allocazione spazio superiore a 256 Gb

Ciao Damiano,

I'm gonna return in English,

You will need a minimal of jfs 3.3. JFS 3.3 has a limit of 1 TB.

What kind of filesystem do you use ?

# fstype -v /dev/vgxx/rvolx

Kind regards,

Re: Allocazione spazio superiore a 256 Gb

Ciao Damiano,

potresti mettere i prossimi post in Inglese in modo che tu possa avere l'aiuto di tutta la comunità di forum?

Translate in English of Damiano:
I wants to create a logical volume of 740 GB but I know that it is not possible to create one more than 256 GB.
How to do it?

Grazie e ciao!
Etto

Re: Allocazione spazio superiore a 256 Gb

Hi again,

There should be no problem creating a filesystem up to 1024 GB on a default 11.i OS.

Could you give us some more information about your volume group (vg01)

# vgdisplay -v vg01

Re: Allocazione spazio superiore a 256 Gb

Damiano,

it depends how you created volume group.
# vgdisplay vgXX
where vgXX is your volume group.
If it is with PE size of 4 Mbytes then you can create a logical volume with max size 256 MBytes.

Best regards,
Ettore

Damiano,

anche Robert ti sta chiedendo di darci maggiori informazioni sul volume group.
Perfavore inserisci l'output del comando

# vgdisplay -v vg01

Ciao.

Re: Allocazione spazio superiore a 256 Gb

I solved the problem recreating the volume group with the following flag:

vgcreate -s 16 /dev/vg01 ....

This gave me the ability to allocate blocks of 16 mb (default is 4 mb).

So I was able to define a logical volume greater than 256 Gb (up to 65535 LE of 16 Mb for a global amount of about 1 Tb).

Thanks a lot for help.
