lvmvgchange and open or not logical volume

Hi,

at this time I want to rename my volume group. Anyway, I did reboot into the single user with boot options init=-bin-bash (debian's testing2.6.17-1-686 runlevel 1 seems not to be a good option for my mountingpartioning problems)

$vgchange -an got: Can't deactivate volume group "volgrp1" with 1 open logical volume(s)

Interesting, $lvs got: LV VG Attr LSize Origin Snap% Move Log Copy% lvaptcache volgrp1 -wi-a- 1,00G lvhome volgrp1 -wi-a- 1,00G lvlocal volgrp1 -wi-a- 2,00G lvlog volgrp1 -wi-a- 512,00M lvopt volgrp1 -wi-a- 2,00G lvsquidcache volgrp1 -wi-a- 1,00G lvsrv volgrp1 -wi-a- 2,00G lvswap volgrp1 -wi-ao 1,00G lvtmp volgrp1 -wi-a- 2,00G lvusr volgrp1 -wi-a- 4,00G lvvar volgrp1 -wi-a- 1,00G

also interesting since, $catproc-swaps

is empty and disabled inetc-fstab: $catetc-fstab proc proc proc defaults 0 0 tmpfs tmp tmpfs nodev,nosuid,mode=1777,size=256m 0 0 tmpfs var-run tmpfs nodev,nosuid,size=1m 0 0 tmpfs var-lock tmpfs nodev,nosuid,size=1m 0 0

$lvm version

got: LVM version: 2.02.06 (2006-05-12) Library version: 1.02.07 (2006-05-11) Driver version: 4.6.0

Any solution, hints, ideas to disable the availability of the logical volumes in the volume group (vg) for renaming my vg? Or is there a bug?

Thanks Olaf
