A thorough guide to persistent storage identifiers in Linux has been missing. These identifiers should be preferred when referencing and accessing devices - and filesystems too. This guide tries to fill that gap: it explains where the identifiers come from, their priorities and reliability. It covers the most widely used storage device types - SCSI, NVMe and ATA, but it also covers Device-Mapper (with its subsystems like LVM, LUKS and dm-multipath), MD RAID, partitions, virtio, MMC, pmem and filesystem identifiers included. The information provided should help readers navigate the identifier space and choose the right ones with confidence.
Hi Peter. Thanks for offering to write this up for Fedora Magazine.
I skimmed your current version. One concern I have is that it appears to be more of a information reference than a guide or a demo. One of the main goals of Fedora Magazine is to promote free/libre and open source software. The information you’ve put together will be useful, but it would probably fit better as a page in the Fedora Project’s official documentation. Would you mind uploading your content to the the Quick Docs? I think what you have would make for a good Understanding and administering storage page under the Usage and customisation section.
Once you have the content in Quick Docs, then you might write a smaller article that demonstrates some common storage configuration tasks using Fedora Linux and that article could reference your larger guide for details.
One advantage of having your reference material in the Quick Docs is that you (or others) can easily update it in the future as needed.
