[linux-lvm] LVM2 strange behaviour

[linux-lvm] LVM2 strange behaviour

[Fred Donck]

Happy new year all,

I am new to the mailing list and a new user of Linux LVM although i have
been using similar technologies for years on Solaris and AIX.

I have some strange behaviour i am encountering on a newly installed
machine.

$> lvm version  
  LVM version:     2.00.08 (2003-11-14)
  Library version: 1.00.17-ioctl (2004-04-19)
  Driver version:  4.3.0
$> 

The machine is newly installed with Gentoo linux 2004.3, latest version.
I installed according to
http://gentoo-wiki.com/index.php?title=HOWTO_Gentoo_Install_on_Software_RAID_mirror_and_LVM2_on_top_of_RAID

and seems to work fine. The RAID-1 partitions work perfectly but the LVM
volumes behave weird.

When i reboot the machine using `shutdown -r' the volumes do not come
online because during boot the vgscan fails with a segfault. I have to
manually do a vgscan and reboot again, then things work ok. Same things
happen when i reboot now: vgscan segfaults, manual vgscan, reboot --> all
ok.

What could be the problem?

Thanks,
Fred

Very funny, I made the same mistake like you. Please upgrade your LVM2 
to the newest version. B-)

Read the thread 'Very long startup times of the lv*-tools'[1][2] for 
further details.
