Linux-tool raid6check controleert RAID6 sneller
Een wijziging in raid6check levert bij een test met een Linux-software-RAID6-array een verdrievoudiging van de snelheid op. De code is opgenomen in de Git-repository van mdadm, meldt Phoronix.

It was also quite a useful exercise in understanding how #mdadm handles failures, and a reminder that the reliability of a RAID array depends on rather more than the disks themselves.
It also surfaced some boot sequencing issues that had been hiding.

TIL regular mdadm `check` operations trigger the `Rebuild` warning. for all arrays at the same time.

ok so my goal now is that i'm going to use mdadm to set up software raid on my existing 2tb drives to turn them into a 4tb drive, with a backup being copied regularly to the new 4tb drive, using it as a backup. this way i get speed advantages but also 4tb of storage.

Lo que te ha pasado es un motivo por el que hay quien prefiere usar siempre RAID por software, nunca por hardware. En windows no se cómo es el tema, pero en Linux mdadm va de lujo.

Makes sense. Though I can't say I know how to setup Grub to boot from a MDADM RAID.
Not that I can afford the extra disks for a RAID setup anyway. ^^;

...and plug it into the internal USB hub I at some point added to the case. Boots fine, but only as a BIOS drive. I do a manual ZFS setup and debootstrap install, then I fuck around with GRUB for... a while... and eventually get it working on a system partition I've set up mirrored with mdadm.

RAID1'de 8 bayt bozdum: 400 okumanın 33'ü yanlış döndü, check 128 saydı, repair bozuk kopyayı sağlama yazdı. RAID5/6'da parite yeniden hesaplandı; raid6check suçluyu buldu.

Slot Zero Is Right: Which Copy Does md repair Believe?
I corrupted 8 bytes on RAID1: 33 of 400 reads came back wrong, check counted 128, repair copied the bad leg over the good one. RAID5/6 recomputed parity; raid6check found the culprit.

I'm in the process of converting an #mdadm RAID10 to a #btrfs RAID10 while preserving the data. My current strategy is:
· ✅ 1 of the 4 disks → btrfs
· ✅ enlarge that disk with another random btrfs disk
· ⏳ copy the 6TB borg repo from the remaining 3 mdadm disks to the new small btrfs pool
· […]

Setting Up RAID1 with LVM on Ubuntu
This guide covers building a software RAID1 mirror with LVM on Ubuntu using two 10TB drives. The combination of mdadm for mirroring and LVM for volume management provides redundancy against single drive failure while maintaining the flexibility to resize, snapshot, or extend storage without repartitioning. Overview The storage stack consists of mdadm software RAID1 at the base layer, with LVM physical volumes, volume groups, and logical volumes built on top of the RAID device.

If the box is dead but drives are intact, don't wait on the warranty fight: pull them and image first (ddrescue, read-only) before anything mounts them. Most consumer NASes use Linux mdadm/LVM or btrfs, so the array can usually be reassembled on a Linux box. What model?
