Okay, you're talking in the context of OpenStack.
You can also check the Nova compute.log for more contextual details of
why the operation failed.

It means, according to libvirt, there's an unfinished `blockcopy` (Copy
a disk backing image chain to destination ) operation.
If you can find the associated libvirt guest name, you can try the
below maybe.
For the Nova libvirt guest that you're trying to create a snapshot of,
find the location of its current block device:
$ virsh domblklist instance-YYYYYYYYY
Then check if there are active block operaations for that disk:
$ virsh blockjob instance-YYYYYYYYY /path/to/libvirt/disk/ --info
If there is any operation and if it is a test environment, you can
run the below to abort the block operation in progress:
$ virsh blockjob instance-YYYYYYYYY /path/to/libvirt/disk/ --abort.
Please the man page of `virsh` for more details.
