a follow-up, the disks on an-worker1175 T396703 and an-worker1199 T409060 are still in a degraded state and have not yet been added to the RAID.
The previous ticket was closed before the remaining steps could be completed. This ticket is intended to track the final RAID work and ensure both systems are fully restored to a healthy state.
Just took care of an-worker1175:
