Is XenMotion possible now? Need to reinstall a complete Pool because of misbehaving XenServer Hosts after applying RBDSR. I don't wan't to reinstall them twice in case it doesn't work yet.

Hi Daniel,
I tested the latest version (commit d7b62cf) on my test environment with migration of image from local storage to Ceph and back. It worked for me, but I can't give you any warranty that it will work in your case.
So you are welcome to test it and give feedback.
Thank you,

Hi Roman,
I did not expect any warranty. Corner cases are not the main issue but i wanted to know if anyone tested basic functionality before im going to invest time settung up my entire pool.
Thanks,

Hi again,
Can you explain your test environment a little bit?
I tried to clean out my hosts from the previous installation but all operations seem instable (sometimes they work, sometimes not). Reinstalled all hosts again and trying RBDSR again on clean hosts next week.

Hi Daniel,
My test environment consist of 5 VM under VirtualBox.
3 VMs - Ceph cluster

Hi Daniel,
Could you please give more details.
What type of storages did you use?
Did you migrate from Ceph or to Ceph? From which type of storage? It would be greate if you can provide the output if these commands:
xe sr-list
xe vdi-list
Thank you.
Best regards.

Hi,
I migrated from rbdsr storage to an nfs rbd ceph brigde (host mounting rbd and exporting xfs filesystem on it with nfs).
I will post some stripped versions of these outputs with only the storages in it that are relevant to the migration.
This morning i shut down the vm, detached the volume, migrated it to nfs rbd brigde from rbdsr, attached again and started the vm again. That worked on the second try.
I also migrated from the nfs rbd brigde to rbdsr with an error but i have no log from that event.
Thank you for your help,
Daniel

Hi Daniel,
I couldn't reproduce the error in my test environment. I checked live migration from RBDSR to NFS and back and it migrated flawlessly
I didn't use Ceph as backend for NFS storage but I think it should't be a reason of problem.
Could you test it again and if problem appears again please send me the /var/log/SMlog and /var/log/xensource.log files from your XenServer host
Thank you.
Best regards.

Hi,
Could it be that the vdi's or sr's are polluted with broken meta information from previous versions? If that could be the case, how do i cleam them?
Sincerely,
Daniel

Hi,
Yes, the meta information for vdi could be broken.
You can clean it using these command:
- Remove the vdi from xapi database using
xe vdi-forget uuid=here put uuid of vdi that you tried to migrate and received error - Rescan SR using
xe sr-scan uuid=here put uuid of RBDSR - Reattach the vdi to VM in XenCenter
