[linux-lvm] Compaq diskarray problems

[Jörgen Winqvist]

Hi,

I can't pvcreate LUN's on a Compaq raid controller. This LUN is 10 Gb.
I've compiled 8.0final.
(I had to comment #include "gnu/types.h" out  in liblvm.h).

Greateful for any help.

Regards

J�rgen

I did try that to begin with. Look further down my posting. Pvcreate
complains on the partition type whatever i change it to. It always says it
has 0x83.

Try the updated lvm tools (SRPM) at:

ftp://ftp.stelias.com/pub/adilger/

This includes a number of patches to the 0.8 final tools that were posted
on this list, but are not in the "official" tools.

Cheers, Andreas

[linux-lvm] Thanks! and Swap on LVM?

Thank you!!!  I usually stay away from SRPM's, but now that I've got
alien, it's not so bad.  'alien --to-tgz' is a dream.  A plus side to
all of this, my pvscan no longer segfaults! ;-)  Neither does my
vgscan! ;-)  I was actually going to sit down with gdb tonight and do
some backtracing when I saw your update.  Very nice to have a 1:00 in
the morning. ;-)  Again, thanks!

OH.  I've noticed a problem as of late.  While trying lvm on both the
2.4.0-test9 and 2.2.17, I have not been able to use an lv device as a
swap device.  The computer starts acting like it's got bad memory and
segfaults during compile time, most notably during kernel compiles.

Has anyone successfully used a lv parition as a swap device???

{good thing I had an extra HD}
