How to extend a filsystem on a AVA LUN

Hi all,

I have a DL585 running RHEL4 connected to an EVA 3000.
I have extended a LUN on the EVA.

The ext3 filesystem was initiallly created directly on the partion /dev/sdc1 (no LVM).

When I run fdisk, the new size of the /dev/sdc device is not detected.

I have rebooted the server, ran hp_rescan -a but the size with fdisk doesn't change.

TIA,

Best Regards,

Rui.

Re: How to extend a filsystem on a AVA LUN

The partition won't magically resize it's self, but the 'disk' (LUN) should show as being larger (the partition not taking all the available space any more).

If this is what is happening, then you need to use your favourite tool to resize the partition, then expand the filesystem.

Most people will use 'parted' (or 'gparted' if you prefer a GUI). From there, an 'resize2fs' or 'ext2online' call to resize the filesystem on that partition.
One long-haired git at your service...

hi Rui,

You may use the attached document for
(1) Resizing the ext3 filesystem. Verify the steps as per the documentation

(2) Procedure for extending LUN on EVA.
(The attachment to this contains VxVM related stuff that you may ignore.

Thanks,
Srikanth

Hi Stuart and Srikanth,

Stuart,

Fdisk is not returning the new size. Do I have to resize /dev/sdc prior to the partion?


Srikanth,

I can not read the attached doc. Can you upload it again?

Thanks!

Rui.
