sudo docker ps -a | grep -Ei 'trilio|tvault|workloadmgr|s3|dmapi|dm_api|datamover|data_mover|contego' # both controllers and computes # if RHOSP 16 or higher, use 'podman'

Then, compare the versions with the official documentation [1]. Navigate through the different hotfixes to find the one that matches all the versions of your WLM elements.

1. Grab the restore ID:

workloadmgr snapshot-list --workload_id a0e61dc0-14eb-4e43-8c4f-ae25ac4fa8c0
workloadmgr restore-list --snapshot_id 546b542a-9fba-4484-848d-da730b4e46c6

2. In the TVM logs, get the ID of the instance that was trying to spin up:

sudo cat /var/log/workloadmgr/workloadmgr-workloads.log* | grep CopyBackupImageToVolume.execute.*ENTER | grep <restore_id> | awk '{print $9}' | cut -f1 -d"," | sort | uniq

3. Grab the host from the OpenStack DB (inside the OpenStack controller):
