[arch-general] LVM volume not active / fails to mount at boot

For some reason, since the last LVM upgrade, one of my LVM volumes fails
to mount, causing the boot sequence to fail.
When I boot, I see the following:
[root at darsys12 ~]# pvs
PV VG Fmt Attr PSize PFree
/dev/sda4 vg1 lvm2 a-- 359.49g 319.49g
/dev/sdc vg2 lvm2 a-- 931.51g 431.51g
/dev/sdd vg3 lvm2 a-- 465.76g 165.76g
[root at darsys12 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
vg1 1 2 0 wz--n- 359.49g 319.49g
vg2 1 1 0 wz--n- 931.51g 431.51g
vg3 1 1 0 wz--n- 465.76g 165.76g
[root at darsys12 ~]# lvs
LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert
lvabs vg1 -wi-ao--- 10.00g
lvcache vg1 -wi-ao--- 30.00g
lvshare vg2 -wi------ 500.00g
lvhome vg3 -wi-ao--- 300.00g
As a result, there's no /dev/vg2/lvshare volume found, and trying to mount
it fails.
I can sometimes fix this issue by removing the volume from /etc/fstab,
rebooting, and then manually issuing "vgchange -ay vg2". But even this
doesn't seem to work reliably. It usually tells me it activates 1 volume,
but sometimes /dev/vg2/lvshare still doesn't show up.
Any idea what the problem might be here / how to fix?
Thanks,
DR
