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@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@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@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
