Bug 146180 – after upgrade to baselayout-1.12.4-r7 lvm2-2.02.06 udev-087, lvm2 can't export logical volumes

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Aben Siatris 2006-09-03 13:24:22 UTC]

system can't boot and mount logical volumes of volume group after upgrade.
I have /usr and /var partition as logical volumes, so my options are very limited.

vgdisplay don't show me any logical volume
vgscan found volume group vg0
in vg0 metadata is all configurations about logical volumes saved correctly. I have backup of metadata too
vgscan read correctly metadata from physical volumes
