Steven Pritchard: RAID - Data Recovery with Open-Source Tools (part 7)
It's becoming increasingly common (in 2009) on desktop PCs to use some form of BIOS-based software RAID. In most cases dealing with a single-drive failure in a software RAID isn't terribly difficult. For example, with NVIDIA's software RAID, even when one drive out of a stripe (RAID 0) set fails, if the drive is recoverable, you can simply clone it to a new identically-sized drive and the RAID will just work. Unfortunately, this isn't so simple with Intel's software RAID, which appears to store the serial numbers of the drives in the RAID metadata, meaning an exact clone won't work. While it would most likely be possible to simply edit the RAID metadata using hexedit to update the drive information, a somewhat simpler solution is to make a backup clone of the drives in the array, then re-create the RAID exactly as it was before in the RAID BIOS, then boot into GNU/Linux and run testdisk on the RAID device. More on that in part 8.

Simos Xenitellis ☛ Simos Xenitellis: How to install and setup the Incus Web UI
Incus is a manager for virtual machines (VM) and system containers. There is also an Incus support forum.
Typically you would use the
incuscommand-line interface (CLI) client to get access to the Incus manager and perform the tasks for the full life-cycle of the virtual machines and system containers.In this post we see how to install and setup the Incus Web UI. Just like the
incusCLI tool that gets access to the REST API of the Incus manager (through a Unix socket or HTTPS), the Incus Web UI does the same over HTTPS. I assume that you have already installed and setup Incus.
