Dear all
I did an upgrade of my Ubuntu 16.04.2 system and when I rebooted my key volume group won’t activate properly. If I do a pvs, vgs, or lvs all the volumes appear good but dmsetup doesn’t show any information
For example I do this and I see the volume (VM70POOL is the VG I am interested in)
>vgs
VG #PV #LV #SN Attr VSize VFree
VM70POOL 1 11 0 wz--n- 1.82t 1.08t
ubuntu-vg 2 2 0 wz--n- 3.64t 48.19g
and
root@vmhost:/var/log# lvdisplay /dev/VM70POOL/health-root-1610
--- Logical volume ---
LV Path /dev/VM70POOL/health-root-1610
LV Name health-root-1610
VG Name VM70POOL
LV UUID jVkRfy-tQ6M-D9RM-xcvO-NxGX-24RY-jQv1r1
LV Write Access read/write
LV Creation host, time vmhost, 2016-11-16 10:10:58 +0200
LV Status NOT available
LV Size 64.00 GiB
Current LE 16384
Segments 1
Allocation inherit
Read ahead sectors auto
But I can’t activate the volume — I get
root@vmhost:/var/log# vgchange -ay VM70POOL

0 logical volume(s) in volume group "VM70POOL" now active
and in kern.log we have "kernel: [ 3819.113149] device-mapper: table: 252:6: linear: Device lookup failed"
Indeed there is no /dev/dm-6 or above
and dmsetup ls shows no sign of the volume
root@vmhost:/var/log# dmsetup ls --tree -o device

└─ (8:5)
ubuntu--vg-root (252:4)

For the record
root@vmhost:/var/log#root@vmhost:/var/log# pvdisplay
--- Physical volume ---

smartmon shows no problem with the disk though I realize that doesn’t necessarily mean anything
FWIW, in one posting I found that someone with a similar problem had there was a suggestion to do vgscan —mknodes
This had no effect.
I have rebooted the machine too
Any suggestions gratefully received?
Many thanks
Scott
