VDI not showing in XO 5 from Source.

wgomes

Just ran the update on Xen today and still have the same problem. "no itens found" when I go to see the disks tab.

@wgomes yup thanks for bumping this topic, still having the problem too

@anthoinebThe problem still persists; when can we expect it to be resolved?

@Team-Storage

I am also having the same issue. Here is link on my forum post:

I have just started having this issue on one Pool yet 5 other pools are fine.
Running XOA 6.2.2.

@acomav it’s disappointing that there seems to be internal knowledge of:

(A) the issue with xcp-ng that triggers this problem but no one has shared the workaround in development to help us to fix it in xcp-ng

(B) the issue with XO failing to deal with this edge(?) case that was introduced in December still hasn’t been reverted.

I would have thought that if we were given the instructions for (A), someone could help with a patch for (B) or we’d just do it manually and (B) wouldn’t be needed.

If we have the information then we can help with the solution rather than feel like we’re living with a festering wound! Seems like a pretty important issue for enterprise software, and I haven’t heard that ‘if you pay money it will be quickly fixed’ - that’s both good and bad. I’d like to think it would be, but don’t want to feel like this community is a sales funnel either!

Anyway, xcp-ng and xo are a gift that I am very thankful for in my small business.

If the people on this thread can help in any way please let us know!

@andrewperry I have support with XOA so will create a ticket.

@andrewperry We're preparing a release of the workaround script that our developers made.

As for the proper fix, it's actually more complex that it may seem, and developers have been working on it for a few months already. If I understood correctly, it's related to the way VDI snapshots are reverted, with responsibilities shared between the storage stack and XAPI, the fixes requiring deep changes in both stacks.

@stormi that's awesome news, thanks for the news.

Digging deeper, I found that my ISOs in my NFS ISO SR have the snapshot-of metadata field populated, and pointing to a VDI that is definitely not its parent. In fact, that parent VDI reports that it is a snapshot-of itself! Hope this helps!

The simplest way to correct those is to forget the VDI and then rescan the SR.

Note: The ISO names will be lost if they were uploaded via XOA, which causes them to be renamed to .IMG files.
