Comment 3 for bug 1844642

it is not realy fixed for me. maybe not the identical scope but i hope for help:

the describe way up to this will work but if i try to backup a 2TB volume and convert to an image, cinder will crash.

command:
$ openstack image create --volume 3c9414bb-98bd-45d4-9b38-2b073e958f81 --disk-format qcow2 "test - snap - vol - img"

$ tail /var/log/cinder/cinder-volume.log

in the same way, the complete controller will unavailable and it will switch to the other one ... this is not so good :( i realy need this volume/image ...

greez & thx, volker...
