XCP host rebooted: VM's wont start anymore :-(
-
@prensel Oh and even reinstalling XOA doesnt work anymore also. bash -c "$(curl -sS https://xoa.io/deploy)" returns without errors but also without creating the XOA
-
@olivierlambert I had two hosts running once but one (xcp-ng-01) was switched off long before this happened. The only host running now is the xcp and didnt gave any (known) issues before,,

In your host, can you do a
xe host-listplease? -

- Please use Markdown syntax over your console copy/paste, I edited your post.
- You need to have the other host online if you want to boot the VM in question.
-
@olivierlambert Ah ok, sorry about the markup.
I cant restart the other host back online because it doesnt exist anymore. -
So why not removing it from the pool then? It's not meant at all to run with a "ghost" machine in a pool.
-
@olivierlambert I just did remove the host but when trying to restart the VM it stiil complains about the SR missing. How can I change this setting for this VM ?
-
Is this SR available?

So you want to start a VM that has a disk on a host which you removed.
-
@olivierlambert
I can see the vhd file on the local disk of this host and it has always been there afaik. The other host wasnt used for this VM. And the VM was running fine without the other host being present for several months. So I assume the disk on this host ? -
Well, you can display the VM disk list with a
xe vm-disk-list uuid=<VM UUID>.Then you can find info on those disks with, for each, a
xe vdi-param-list uuid=<VDI UUID>.Then, you'll see on which SR are each disks, and you'll understand why the VM can't boot.
-
I'm trying to understand how it is possible that this vm has been running for a few months without the other host being present ? Where would have the vhd file been stored ?
I have a copy of the vhd file here, can I create a new vm with that ? -

Your

I really cant see the problem
