Backup of a Windows VM failed when the backup disk became full
the guest continued to run
Upon reboot the guest failed to start
Error: start failed

The logical volume info from lvdisplay looks like this:
--- Logical volume ---
LV Path /dev/pve/base-100-disk-1
LV Name base-100-disk-1
VG Name pve
LV UUID UBu5B1-6gQp-nSnH-NypB-S83B-h2tL-BLTx5Z
LV Write Access read only
LV Creation host, time bastet, 2018-08-08 10:59:57 -0700
LV Pool name data
LV Status NOT available
LV Size 155.00 GiB
Current LE 39680
Segments 1
Allocation inherit
Read ahead sectors auto

I've tried lvchange -ay /dev/pve/base-100-disk-1

no change: LV Status NOT available

I added /dev/pve/base-100-disk-1 to Datacenter storage
when selected the status reads
Enabled Yes
Active Yes
Content Disk image, Container
Type LVM
Usage 96.56% (449.00 GiB of 465.00 GiB)

What steps need to be taken
to get this logical volume active/available
mounted and/or recognized by the host
and the guest started?

Thank you,

SOLVED:

edited /etc/pve/qemu-server/100.conf
removed lines template: 1 and redundant non-existent virtio2: /dev/disk/by-id/UUID- blah...
cloned the guest to a new VM
started the cloned VM
