Hi,
There are 2 scenarios
1. Migration from one pool to other works perfectly when instance is not
running.
2. When instance is a running
Individual volumes can be migrated without any issue.
If I perform instance migration to another host by selecting “migrate
storage” its getting failed. Though storage pool is shared across all the KVM
hosts.
This is the case I have raised for the same:
https://github.com/apache/cloudstack/issues/8190
As I said I can do migration of either root/data disk separately even when VM
is running, however if I select option "instance migration with storage" its
giving error. Below are the steps I'm trying to achieve
select instance: click on migrate instance to another host option,
select target host and select migrate with storage option, choose
storage and click okay.
EXPECTED RESULTS
instance should migrate to target host along with the volumes/disk migration as
specified in the above steps.

Punitha HS

Hi Punitha,
It can depend on case-by-case basis for managed storage. For Powerflex live VM
migration with storage between two storage pools seems to be supported as per:
https://urldefense.com/v3/__https://github.com/apache/cloudstack/pull/7408__;!!LpKI!jAqmOTlAzvlR0avgaUyh-aMePM5QvJFShB7Xxhbb840HnXMXtx98V28RduSdwqI9_4M097CNTwS33GVLMgBr-Bs$
[github[.]com] and
https://urldefense.com/v3/__https://docs.cloudstack.apache.org/en/4.18.1.0/adminguide/storage.html*migrating-a-instance-root-volume-to-a-new-storage-pool__;Iw!!LpKI!jAqmOTlAzvlR0avgaUyh-aMePM5QvJFShB7Xxhbb840HnXMXtx98V28RduSdwqI9_4M097CNTwS33GVLxSLjHRg$
[docs[.]cloudstack[.]apache[.]org]
Quoting the docs: "In case of KVM and PowerFlex/ScaleIO storage, live migration
of instance’s root disk is allowed from one PowerFlex/ScaleIO storage pool to
another, without stopping the instance."
It could be that you've hit a limitation or even a bug. If your env matches the
recommended and supported PowerFlex setup, then you could log an issue at
Github.

Hi,
I'm using PowerFlex storage.
Individually I'm able to migrate volumes from one storage pool to other pool.
However when I select migrate storage during VM migration its giving error.
Failed to migrate VM [VM instance
{"id":28,"instanceName":"i-2-28-VM","type":"User","uuid":"9babb438-0e57-4d1a-9551-09a17bcf8989"}]
along with its volumes due to
[com.cloud.utils.exception.CloudRuntimeException: Copy volume(s) to storage(s)
[{volume: "45", from: "8", to:"7"},{volume: "44", from: "8", to:"7"}] and VM to
host [{vm: "28", from: "9", to:"10"}] failed in
StorageSystemDataMotionStrategy.copyAsync. Error message: [Migrating a volume
online with KVM from managed storage is not currently supported.].].
