Live Storage migration between ceph on Ubuntu 20, does not work

[happyalexkg]

Hello, Team I tring use Live Migration with Volume Migration with Shared Storage (Ceph) on KVM (Ubuntu 20). But it's failed with:

2022-12-02 09:58:27,651 DEBUG [o.a.c.e.o.VolumeOrchestrator] (Work-Job-Executor-92:ctx-136c4df4 job-442/job-443 ctx-6b9bcc45) (logid:ca6829a0) Failed to migrated vm VM instance {id: "87", name: "i-2-87-VM", uuid: "0780ecb5-a878-4553-8d94-8538a3fff08c", type="User"} along with its volumes. Can't find strategy to move data. Source Host: ceph-osd01, Destination Host: ceph-osd02, Volume UUIDs: c252edd8-5119-4d70-b3b6-65bca49beeba

I'm tring migrate Vm from one Ceph Pool to Another Ceph pool. Both in same Zone and Cluster CloudStack 4.17.

@happyalexkg is this something you were able to do in older versions? I am not sure if this was ever implemented.

cc @wido @weizhouapache do you know if we ever supported live VM migration with storage, from one ceph pool to another ceph pool. I think if it's not in the same cluster, live VM migration won't work. @happyalexkg can you see if cold migration (VM off) works?

@rohityadavcloud @happyalexkg I have ever seen this error when live migrate vm on a ceph storage to another ceph storage. it works between NFS storage pools.

Technically Ceph can do a RBD migration from one to another Ceph storage pool, but this has to be in the same cluster. I don't think CloudStack supports this though.
