Restart the toolstack on each server.

You should be able to delete the snapshots without causing any harm. A couple of things to keep in mind --

• If the snapshot is associated with an existing backup job, then the next run of that job will result in a full backup instead of a delta

• It may take some time for the snapshots to coalesce following deletion, so this could still affect your backups until they are completely removed

• If you want to delete the backups associated with the old job, then you can from the Backup > Health tab in XO

It is also possible to perform this activity from within XO as described here. There are some prerequisites for performing this action that you should review -- https://docs.xcp-ng.org/installation/requirements/#-pool-requirements

I would setup a Continuous Replication backup job to create a duplicate VM on the new storage repository. When you are ready to perform the cutover, shutdown the original VM, perform one final run of the CR job, and then start the new VM on the new pool.

Interesting read that mentions xcp-ng!

Yes, it's technically possible, as long as the underlying hardware is compatible. For example, you can't put a server using AMD processors into a pool with Intel processors.

The server being moved into the existing pool will lose its local storage and all VMs stored there, so you will need to migrate those VMs to the main pool before the server is merged. Afterwards, you can move them back if desired.

@BrianDLC The error ""EACCES: permission denied" should have pointed you to a permissions error to begin with.

Since we have no knowledge of how that script operates, it often makes more sense to refer you to their repo for help rather than us guessing at the reason for the issue.

@Ascar I suspect that Olivier means to register with the XO instance using this syntax --

xo-cli register [--allowUnauthorized] [--expiresIn <duration>] [--otp <otp>] <XO-Server URL> <username> [<password>]

You can run xo-cli without any parameters to get the full usage text.

@henry.lin0u812 I verified that it works correctly for me when using quotes around a password with spaces, so something else is happening on your end. I would verify the username, password and URL.

@CodeMercenary said in What's the recommended way to reboot after applying XCP-ng patches?:

In other words, can I just Install Pool Patches and then reboot the hosts starting with the master if I don't care if the VMs are shut down?

Yes

I haven't tried this, but did you try wrapping the password in quotes?

Technically, you can still perform the Install pool patches option to update all hosts at the same time. Then you should reboot the pool master, followed by the other pool members.

The issue is that rebooting any host or restarting the toolstack on any host will cause the VMs to start back up if they have the Auto power on option enabled.

@CodeMercenary You can disable each host in it's Advanced tab in XO, which will prevent these VMs from restarting during the patching process.

Just be sure to enable the hosts once the patching is completed.

@DustinB RPU isn't available in this case because the VDI aren't on shared storage.

This is how I setup my Postman --

This is on the root folder, and Auth Type for all requests are set to Inherit auth from parent. {{token}} is an environmental variable, so it can easily be updated in a single location. Also, this allows you to easily switch environments to go from XOA, XO from sources, etc.

Hi @PGibson,

FWIW, I believe it is trying to reach xen-orchestra.com, not .net. Did you configure a DNS server when you setup the static IP? Post the output of cat /etc/resolv.conf on the XOA VM.

Regards, Dan

You can migrate to XO VM the same as any other VM.

At which level are you wanting to add a network (pool, host, or VM)?

Hi,

I don't believe that this is available yet via the REST API, but you can do it using xo-cli.

Regards, Dan
