Creating local ISO SR failed -> Feature request
-
I followed: https://github.com/xcp-ng/xcp/wiki/Create-a-local-ISO-repository but ended up with an error, all the time:
admin@admin.net SR_BACKEND_FAILURE_226(, Invalid local path, )Via XCP-ng console, I created the parth (in this case /isos) by hand and redid the steps -> SR created.
It's probably missing anI suggest mkdir, if the directory doesn't exist.As the howto probably worked, I guess it got lost by one of the updates?
Edit: I didn't read carefully enough, but this can still be considered as a request (as I didn't see a GH repo to make them)
-
Your path needs to be the same directory your created on the xcp-ng host. You have "/test" in the path currently and not "/isos".
-
The screenshot is an example. If the option to create a "local" SR inside a mounted filesystem is given, it makes totally sense to check if the directory exisits and - in case it doesn't - to create one. There's IMHO no need to force someone to create it by hand before.
2nd step would of course be an option, to upload the ISOs via webconsole.
Edit: Fixed the startpost.
-
That's because how XAPI works. You can't create a folder remotely via the API, the path has to exist before.
-
As XOA needs the root password and IP of the XS/XCP-ng host, it has everything, it needs.
It could be SSH'ed to create the folder (could be a manual switch without check - if it fails, it fails).But I accept, if you don't want to go ways around XAPI.
-
That's precisely something we want to avoid: having to connect outside XAPI. Also we have no way to know if:
- root password is still enabled on SSH
- we have SSH access to the host (only 443 can be used for XAPI)
Last option is to use a XAPI plugin we build ourselves to do that. But it must be secure enough to avoid folder creation anywhere.
-
How hard is it to SSH in and manually create the folder? It's 10 seconds worth of work tops. And you probably will never have to ever touch it again.

It's about optimizing things and taking away extra/manual steps that disturbs workflow with rather low effort to implement
.
I'm not feeding your negative vibes on that, so discussion is over for me. Oliver said they don't want to do things beside what XAPI can do and thereby it's done. -
We are just talking, indeed
I'm always open to suggestions, and as I said, there's still one possibility (XAPI plugin) but it might be done carefully to avoid security breaches.Maybe having the folder created by default is another option. In the end, we could create that folder "by convention".

There may be something I didn't get, but if you don't want manual steps that disturb the workflow, I suppose you've got many hosts to install. If you've got several hosts to install, I hope you have a file server with an NFS or SMB share where you could put ISOs on?
-
I'm just installing it on a smaller number of independent servers. I can't use an ISO share for that.
But I'm not limiting that to me: Other people have to do the same stepts manualls.
It's one change, that - in the long run - can save thousands of manual steps in the community.
The feature is pretty nice for smaller environments, especially as new servers often don't have optical drives anymore and using iLO for that requires an advanced license, which is not super cheap (relative to the price of smaller servers).Edit: And yes, of course the 2nd thing would be an "upload" button, to use XOA to drop the ISOs there. (Or did I just miss that?)

That would be quite easy to do for future releases indeed.
-
One option, considering a single server, you would have a local SR. Create there a "ISO folder" and mount it, like ESXi do, using the XO interface to manage the files.

It's what the whole topic is about.
-
@cg Not create a folder inside the host, create it inside a Local SR. Unless I completely misunderstood the problem.
-
@Carlos-Raasch it doesn't work like that. You should keep the "VM" SR untouched, because you have no control on what XAPI/storage need or will do inside it.
-
@olivierlambert I thought of this possibility because looking at the host file system the local SR appears as a simple mount point.
Surely it must be a lot more complicated than that.

It's a mount point, but a SR rescan can fail if it doesn't have what's expected inside. That why we tend to avoid doing any manual step inside a SR.
-
Maybe ... is it possible to convert the ISO to VHD, to be properly stored in the SR? I did a quick search but only got Azure related stuff.
-
No it's not how it works in XAPI. You need a dedicated ISO SR using only *.iso file name/extension.
