[linux-lvm] using 160GB IDE drives under linux with LVM.

[linux-lvm] using 160GB IDE drives under linux with LVM.

[Terje Kvernes]

  first, I'm sorry for asking here, but I'm close enough on topic (I
  hope :) and I know there are bright heads who deal with linux at
  this level out there.  I've also looked through google, and at the
  kernel IDE-documentation.  and the little thing that lingers is
  128GiB.

  fdisk is only able to address 128GiB, that's rather obvious.  if I
  make one partition, it's about that size, and if I make two
  partitions, the first one 100GiB, the last one will only be about
  28GiB.  if I pvcreate the device itself it helps a little, but not
  much.  /proc/lvm/global then returns the size as 134152192KB.

  now, I've added SCSI-devices that where > 500GiB with ease into LVM,
  but here I stumble.  is there some easy solution out there that I've
  missed?

  the box currently runs vanilla 2.4.16, only patched with LVM-1.0.1
  from 26/11.  patches or anything people want to toss at this will be
  highly appreciated.  we have two of these beasts from Maxtor, and
  stand to loose about 60GiB of space, which isn't all that neat.

Why make a partition at all?  Why not just make a physical volume out of
the whole disk?

NAME
       pvcreate - initialize a disk or partition for use by LVM

SYNOPSIS
       pvcreate  [-d|--debug] [-f[f]|--force [--force]] [-y|--yes] [-h|--help]
       [-v|--verbose] [-V|--version] PhysicalVolume [PhysicalVolume...]

DESCRIPTION
       pvcreate initializes PhysicalVolume for later use by the Logical Volume
       Manager  (LVM).   Each  PhysicalVolume  can  be a disk partition, whole
       disk, meta device, or loopback file.  For DOS disk partitions, the par­
       tition  id  must be set to 0x8e using fdisk(8), cfdisk(8), or a equiva­
       lent.  For whole disk devices only the partition table must be  erased,
       which will effectively destroy all data on that disk.  This can be done
       by zeroing the first sector with:

       dd if=/dev/zero of=PhysicalVolume bs=512 count=1

       Continue with vgcreate(8) to create a new volume group on  PhysicalVol­
       ume,  or vgextend(8) to add PhysicalVolume to an existing volume group.

Whats your Extent size? if its the default 4MB that allows you to address
256GB in that volume group.... Please do a vgdisplay -v

You only use that disk for linux? do you need it to be partitioned at all?
Do you want the whole of the disk to be available under LVM?  You could do
your pvcreate on the whole device that would get arround partition table
addressing problems.

This is a kernel IDE driver limit.  You need to patch with Andre Hedrik's
IDE patches to support IDE devices over this size.

Is this specific to 2.4.X kernels?  I'm running 2.5.0, and I just noticed
that the 160 gig drives I was using are also partitioned at only 128Gigs.

    No, it's at the IDE driver level. There are patches to get around
    this that are being considered for the mainstream kernel (Andrei H.
    I believe). 

    Brave man running 2.5.0, the dot-zero release of a development
    kernel.

The IDE stuff didn't go into the 2.5 tree until 2.5.2-something.

[Kirby C. Bohling]

Why is he brave, it is just a converted 2.4.15-pre5 with a change to the 
version number if I remember correctly that has a filesystem bug when 
you umount during a reboot.  As long as he doesn't reboot and/or umount 
his data is save. :-)

    I thought there were more changes than that. 

    2.5.x is the development series, not the stable series.

Not that the 2.4.x series is very stable anyway, with problems of different sorts (APIC for example)..

    And problems with the high memory VM (DAMHIK), and...

    But if the stable series isn't, how is the unstable going to be
    better?

  like I said, if I pvcreate the device itself, /dev/hdc,
  /proc/lvm/global then returns the size as 134152192KB.  so it's
  still off.  :/

  nope.  I have two other 100GB drives in the box.

  yes, please.  :)

  oddly enough, that doesn't seem to work either.  unless 134GB is
  160GiB.  and unless my math is _very_ off, this seems strange.  :)

  at least I'm not the only one who can't spell his name when looking
  for the patches, "Andre Hedrick".  right then.  I'm patching and
  compiling now. 

  aah...  thank you.  152.62GB.  now that looks more like the sort of
  Gib / GB tradeoff I can live with.

No-one seems to have mentioned the nub of the issue:

    /dev/hda would have been 128 GiB in size.

So trying different tools/techniques won't help you one bit!!!

The problem is the IDE limit. IDE has 28 bits to address the block. The
block is 2^9 bytes. So the maximum device size is

    2^(28+9) B = 128 GiB ~= 137 GB.

Maxtor have addressed this limit with their "Big Drive" scheme
(http://www.maxtor.com/products/bigdrive/ - read the white paper), which
extends the address size from 28 to 48 bits. This extends the maximum
device size to

    2^(48+9) B = 128 PiB ~= 144 PB ~= 144,115,188 GB

This of course means an updated version of the ATA interface
specification, which in turn means that you need different software
drivers.

In the Linux world this means you need kernel patches in order to access
the portion above 128 GiB.

I am very pleased to learn that Andrei has made a patch. Now I can
cheerfully go out and buy 160 GB drives knowing that I can get Linux to
see the whole drive - cool!

One wonders how long it will take the other operating systems to catch
up with Linux (again) :-)

That's just "134152192 KB / 1024 MB/KB / 1024 GB/MB = 127.937 GB"
which is close enough to 128 GB ;-)

Of course they are not. But if you are having problems with one kernel and can't get around it it might be a good idea to test another kernel...


Oh, by the way... have a look at http://www.linux-ide.org/ -...
