Team,
When deleting an iscsi disk , it gets stuck in deleting, and find the error logs in the PEtaSan logs,

consul kv delete -recurse PetaSAN/Disks/00456 to delete the particular disk, but the error pointing to no snapshot for the  image,
How can i fix this ?

I  trigger the python script from /opt/petasan/scripts/util/delete_iscsi_disk.py, but getting similar error.

Is there another way to delete the these disks ?

Pls help

Noticing that , it keeps retrying and deletes the disk finally.

if the iSCSI disk is not started in the UI, you can use ceph rbd command to delete image.
