extendfs licence problem

[Mustafa Gulercan]

Hi gurus;
i would like to extend vxfs file system on HP-UX 11.23 ia64.
From 2TB to 3TB.
i did extend vg and lv.and after while i am extending file system i took this error;

# extendfs -F vxfs /dev/vgpstn/lvpstn
extendfs: You don't have a license to run this program

Any suggestions will be pleased

regards;

Hi:

The limit for a logical volume on 11.23 is 2TB:

--- Logical volumes ---
LV Name /dev/vgpstn/lvpstn
LV Status available/syncd
LV Size (Mbytes) 3085888
Current LE 48217
Allocated PE 48217
Used PV 2

then how can be LV size 3 TB ?

[Geoff Wild]

You need onlinejfs to be able to grow a "filesystem" over 2 TB.

Hi (again):

Read the footnote in the document I cited.

Size of a LV 11.11 & 11.23 --- 2 TBytes
[I/Os beyond 2TB will be rejected]

Page 11 of this doc:

http://docs.hp.com/en/5991-2762/5991-2762.pdf

"However, only file system
upto 32TB has been qualified and will be supported as of this stage.Also, the OnlineJFS
license is required to create file systems over 2 TB and under 32TB. The EBFS license is
required to create file systems over 32TB."

Hi :

...and to add to Geoff's pointer, the document he references ALSO notes:

"LVM, also supports creation of VxFS file system, of size, less than or equal
to 2TB."

..also on page-11...

we have no Online JFS at this system.
So now i have to roll back to 2 TB size LV.
can i use lvreduce?
OR
would it be risky mounting now for a while without reducing LVM?

[James R. Ferguson]

HI:

Since you haven't been able to extend the filesystem housed within the logical volume, you should be able to safely 'lvreduce' the logical volume without corrupting the filesytsem therein. Be very careful not to reduce the logical volume to less than the extent of the filesystem.

Of course, a backup of the filesystem beforehand is the proper insurance to avoid the unforseen :-)

what about mounting now for a while without reducing LVM?

[James R. Ferguson]

Hi Mustafa:

> what about mounting now for a while without reducing LVM?

My answer would be the same as before. You should be able to use the filesystem without problems despite the fact that its container (the logical volume) is larger.

Pls read the above explanations.
without Online JFS there is no way to extend file system more than 2TB.

Thanks for Gurus'.
