[linux-lvm] vgscan eating memory

[Tarmo Samuel <sam@smartlink.ee>]

Hello,

after upgrading to Slackware 10.0, I ran into a problem with LVM2.

system: Slackware Linux 10.0
kernel: 2.6.7-mm5
Official slackware packages:
device-mapper-1.00.17
lvm2-2.00.15

Problem: lvm vgscan runs, eats up more and more memory until it gets 
OOM-killed.


When run, it says:

  Reading all physical volumes.  This may take a while...
  Ignoring additional label on /dev/hda11 at sector 1

and keeps on munching the disk.

(/dev/hda11 is a LVM partition)

I'm not sure how to debug it. strace shows n * 
(read,ioctl(BLKBSZGET),_llseek) and a few brk's occasionally..... No 
errors get logged or displayed, except the fishy notice about additional 
label.

When I use the OLD lvm2 binary (2.00.08), it works just fine (was 
running the same kernel and same version of device-mapper before, too).

Neither of the lvm packages have any patches applied to them. 
Slackware's package is ./configured with --enable-static_link and 
--with-lvm1=internal. My old package was configured with --with-lvm1=shared.

Any hints would be welcome.
