XenMotion Live Migration not available? #37

dlux95 · 2017-04-28T02:01:54Z

The Readme states that migration is supported. Trying to do that in XenServer 7.1 with Ceph jewel is not working.
XenCenter reports: You attempted to migrate a VDI to or from an SR that doesn't support migration
I don't see any errors in SMlog or xensource.log
Tracking that issue down to the xapi script that handles migration its about the capabilities listed in RBDSR.py
Missing capabilities compared to NFS: SR_CACHING, VDI_GENERATE_CONFIG, VDI_MIRROR and VDI_RESET_ON_BOOT/2 but because it is not missing any capabilities compared to ISCSISR that can not be the reason.
Hopefully you can resolve that issue,

Thank you in advance

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,
Roman

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,
Daniel

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
2 VMs - XenServer hosts in pool

Hi,

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.
Roman

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 Am 12.

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.
Roman

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

rposudnevskiy · 2017-05-19T12:45:25Z

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
