RAIDing with LVM vs MDRAID – pros and cons?
In his answer to the question “mixed raid types”, HBruijn suggests using LVM to implement RAID vs the more standard MDRAID.

Can I create a software RAID 1 with one device
I have a single disk that I want to create a mirror of; let’s call this disk sda. I have just bought another identically-sized disk, which we can call sdb. sda and sdb have one partition called sda1 and sdb1 respectively.
New RAID array will not auto assemble, leads to boot problems
I had just asked this question where I was unable to boot after installing a new RAID1 Array. I was able to get to the terminal, but once I sorted that out I realized that my problem isn’t so much an fstab boot problem as an mdadm auto assemble problem.

1st attempt: Mounting disks alone
Mounting multiple devices at a single mount point on Linux
Is there a way to mount multiple hard drives to a single mount point? Let’s say I run out of space on /home and decide to add an extra hard drive to the computer. How do I scale the space on a mount point? If I use RAID, can I add drives on the fly to increase space as I run out of them? Is there an alternative to using RAID if I am not interested in maintaining a high level of redundancy?
bit rot detection and correction with mdadm
I’m about to re-organise all my HDDs in my home linux box nas and would like to use mdadm raid for data protection and its flexibility for reshaping the arrays. However, before I use mdadm for this I’d like to know how it handles bit rot. Specifically the kinds of bit rot that do not result in unrecoverable read error messages being sent from the HDD.
Linux raid disappears after reboot
My troubleshooting ability in Linux is not impressive, just so you know. I can follow instructions very well on the other hand. I have a Linux server with Linux raid. It was working well with no problems for about half a year but then I had a power failure and have been getting the same problem ever since. After rebuilding the raid all my files are still there, so that’s a good thing. When I reboot the server the raid device md0 is gone.
Can I get SSD rw performance while keeing data security if I combine SSD & HDD in btrfs RAID1
I have 2 storage devices; classical slow HDD (750GB, /dev/sda) and faster SSD (128GB, /dev/sdb). Currently I have installed Ubuntu & Mint on same btrfs partition on SSD (/dev/sdb5). My btrfs pool consists of /dev/sdb5.
