Incomplete volume groups will be activated read-only. 7 PV(s) found for VG vg1: expected 8 Logical volume (lv1) contains an incomplete mapping table. 7 PV(s) found for VG vg1: expected 8 Logical volume (lv1) contains an incomplete mapping table. 1 logical volume(s) in volume group "vg1" now active Which looks like it might have worked, but in /dev/mapper I have: crw-rw---- 1 root root 10, 63 May 30 02:48 control brw------- 1 root root 254, 0 Oct 25 13:20 vg1-lv1 But I can't mount vg1-lv1 (its ext2 - but it says "must specify fs type). What is wrong? Have I misconfigured lvm / dm? are there any lines I need in my config file? Are there any tools I can run to get more info? The array was built with LVM1 & 2.4.18, I'm now using LVM2/DM under 2.6.11.10 Also, It looks like it has done something, because if I try to deactivate it with "vgchange -P -a n vg1" I get: Partial mode. Incomplete volume groups will be activated read-only. 7 PV(s) found for VG vg1: expected 8 Logical volume (lv1) contains an incomplete mapping table. Can't deactivate volume group "vg1" with 1 open logical volume(s) Any help greatly appreciated. Kind regards, Tom
