In my hometinylab one of my "servers" is running XCP-ng based on Xenserver (the other "server" of two). For more details look at the drawing of my setup. For the moment the XCP-ng host used in my hometinylab is low on memory (only 4Gb of memory installed). But nevertheless it can be used to learn and to discover how a virtualization host works. Because I am not using enterprise level hardware, XCP-ng is one of the virtualization software platforms that almost work on everything out of the box. The only drawback is the management tools to install and to configure. We will have a look at Xen Orchestra Web Interface for Xenserver (XOA), also the windows management tool XCP-ng center and the command line interface in other future posts. Other sofware that I used is Advanced IP Scanner.
The migration steps. 1. Stopping the services that use the dataset. (recommended). 2. Replicating the dataset to the new pool. 3. Verify that all data is replicated. 4. Put in operation the new dataset. 5. Delete the old dataset when satisfied (or not). The video tutorial can be found by clicking on the title or the picture below. How to migrate a dataset from one pool to another in TrueNAS CORE 1. Stopping the services that use the dataset (recommended). Go to the services tab and what I do if not certain of which services are used by the dataset I let only running the services from which I am cetain that they do not use the dataset. Also, control jails and Virtual Machines to be sure that they do not use the dataset. In the video I do not stop the services to show it is possible. 2. Replicate the dataset to the new pool. a. go to Tasks --> Replication Tasks b. add new replication task c. select source location (example select on this system source /mnt/volume1/VM iso) d. sel...
