[linux-lvm] rootfs on lvm2 and vgchange: Can't deactivate volume group "vg_sys" with 4 open logical volume(s)

[Arkadiusz Miskiewicz <arekm@pld-linux.org>]

Hi,

I'm using kernel 2.6.7 with lvm2:
[root@anduril /root]# lvm version
  LVM version:     2.00.17 (2004-06-20)
  Library version: 1.00.17-ioctl (2004-04-19)
  Driver version:  4.1.0

[root@anduril /root]# lvdisplay -C
  LV      VG     Attr   LSize  Origin Snap%  Move Copy%
  lv_home vg_sys -wi-ao 25.00G
  lv_root vg_sys -wi-ao  3.00G
  lv_tmp  vg_sys -wi-ao  2.00G
  lv_var  vg_sys -wi-ao 15.00G

root filesystem is on LVM (on lv_root) so I'm starting lvm from initrd:
LVM_SYSTEM_DIR=/tmp lvm vgscan --ignorelockingfailure
LVM_SYSTEM_DIR=/tmp lvm vgchange --ignorelockingfailure -a y vg_sys
it works fine.

Then when my initrscripts run vgscan && vgchange -a y to activate potential 
other vgs it complains:
Can't deactivate volume group "vg_sys" with 4 open logical volume(s)

I have no idea why it want's deactivate it if the command is ,,-a y'' so the 
task it to activate it. Reasonable would be: if active then do not touch.

[root@anduril /root]# vgchange -ay vg_sys
  Can't deactivate volume group "vg_sys" with 4 open logical volume(s)
[root@anduril /root]# lvchange -a y vg_sys/lv_tmp
[root@anduril /root]# lvchange -a y vg_sys/lv_home
[root@anduril /root]# lvchange -a y vg_sys/lv_var
[root@anduril /root]# lvchange -a y vg_sys/lv_root

vgchange -ay with verbose below.

(tested cvs version of lvm2 from today, too - same results)
