Import from VMware fails after upgrade to XOA 5.91

khicks

Hooray, fix_xva_import_thin works! Huge thanks to @florent for the fix!

FWIW, jumping around between commits was a breeze thanks to that external tool.

FYi, jumping into various commits is simply a git checkout <target commit>

@acomav said in Import from VMware fails after upgrade to XOA 5.91:

redid the job with a snapshot from a running VM to a local SR. Same issue occurred at the same time.

I too did the same thing; it didn't work for me either.

He is what did work:

Ran quick deploy
https://xen-orchestra.com/#!/xoa
It installs an older version (don't remember the version).
I had it do one upgrade which takes it to XOA 5.90.
Once it did that, it let me do the import from esxi.

olivierlambert

5.90 is the current stable release channel, without the speed improvement (and the bug). We'll have a patch release for 5.91 (current latest) that will solve it

archw

@olivierlambert
Thanks!

florent

@khicks : that is a great new

@archw @jasonmap @rmaclachlan I pushed a new commit to the branch fix_xva_import_thin , alignining the last block to exactly 1MB . Could you test if the imports are working now ?

For those who have an XOA and want to help, please open a tunnel and send me the tunnel yb chat ( not directly in this topic) , and I will patch your appliance

FOr those who use XO from the source , you'll need to change branch

@florent

Over the weekend I spun up an XO instance from source. This morning I changed to 'fix_xva_import_thin' after your post. Unfortunately, still the same failure for me. Only notable difference I see is that your ${str} addition for the log now comes back as " undefined"

Here are my logs:

I patched my XO source VM with the latest from 5th Feb and still had the same error.
"stack": "Error: no opaque ref found in undefined

It may be I am not patching correctly so I have added a XOA trial and moved to the 'latest' channel and have ping @florent with a support tunnel to test in the morning.

florent

@acomav you're up to date on your XOA

I pushed a new commit , fixing an async condition on the fix_xva_import_thin branch . Feel free to test on your XO from source.

rmaclachlan

Thank you @florent for all your help! We got the VM to import now, I will try the other failed VM outside business hours but I expect it will work now as well!

@florent Nice! This latest change allowed my migration to complete successfully. Seems like the peak transfer speed was about 70Mbps. 4.77GB in 5 minutes. I'm guessing the thin/zeros made this so fast?

yay
the thin make it fast(espcially since it only need one pass instead of two in the previous api), XCP is a little faster to load xva , and there is some magic . No secret though, everything is done in public

we invested a lot of time and energy to make it work fast, and we have more in pipeline, to make it work in more case ( vsan I am looking at you) or to access more easy the content of running VM

rmaclachlan

Just a quick update - I imported a handful of VMs today and was even able to move over the VM that failed on the weekend so I think that patch works @florent

acomav

@florent
Thanks. I have kicked off an Import but it takes 2 hours however....the first small virtual disk has now been successful whereas it was failing, so I am confident the rest will work. Will update then.

Thanks

@acomav

Import completed. Great work @florent.

Hi, a question about these patches and thin provisioning.

My test import now works, however, it fully provisioned the full size of the disk on an NFS SR.

[root@XXXX ~]# ls -salh /mnt/NFS/d8ad046d-c279-5bd6-8ed7-43888187f188/
total 540G
4.0K drwxr-xr-x  2 root root 4.0K Feb  6 09:33 .
4.0K drwxr-xr-x 27 root root 4.0K Feb  1 21:22 ..
151G -rw-r--r--  1 root root 151G Feb  6 10:45 1c3b93da-de07-4a4f-8229-60635bc2f279.vhd
 13G -rw-r--r--  1 root root  13G Feb  6 09:43 1eae9130-e6eb-45be-ae25-a7dcb7ee8f4e.vhd
171G -rw-r--r--  1 root root 171G Feb  6 10:51 751b7a5f-df32-4cb1-9479-e196671e7149.vhd

The two large disks are in an LVM VG on the source and combined, use up 253 GB of the 320 GB LV. They are thin provisioned on the VMware side.

Am I wrong to expect the vhd files on the NFS SR to be smaller than what I see? Does LVM on the source negate thin provisioning on the xcp-ng side?

Not a big deal, I am just curious.

Thanks

florent

thank you all, now time to do a patch release

LVM is thick provisionned on XCP side : https://xcp-ng.org/docs/storage.html#storage-types

olivierlambert

@acomav How big are you original VM disks? (eg the total disk size on VMware)

acomav

@florent The VM is on an NFS SR which is thin provisioned. LVM is inside the VM on the virtual disks.
