Started #zpool shinannigans. I'm switching from RAIDZ1 to Stripe storage type and want to remove two old, smaller drives. At the end, it should be one of those:

1. Same storage size, less power consumption, colder NAS, faster storage, and two empty drive bays.

2. Lost data, fire, and explosions.

#Proxmox / #KVM: Ist es geschickter, zwei als Datenspeicher genutzte #Raid1 als "Festplatte" in die VM zu geben, und dort #LVM aufzusetzen, um die beiden zu verbinden. Oder sollte ich LVM auch auf dem Host aufsetzen und als virtiofs in die VM geben?
Ich tendiere zu ersterem.

Ah, the thrilling saga of a #techie setting up a #FreeBSD home #NAS because apparently, Netflix wasn't entertaining enough 🤓. In a riveting tale of #RAID1 configurations and SSD slot descriptions, the author bravely sacrifices their social life to the gods of data redundancy 💾. Meanwhile, the rest of us are still trying to figure out how to connect our WiFi 📶.

Random update that hits both my #photog and #sysadmin roles; I ran out of disk space for my raw #photography recently. I have a home-made #NAS box with a pair of disks in #RAID1 running Rocky Linux and I needed to get more space. I spent an evening shopping around for the best value I could get in local disks and that required driving to three Canada Computers locations to pick up one drive at each so I could build a #RAID5 array and not deal with this again in the near future.

Ich brauche nochmal #Brainpower der #EDV #Bubble 🤣

Da mein bisheriges, betagtes, leistungsschwaches 1-Bay #QNAP #NAS sehr langsam ist, z.B. beim #rsync, habe ich inzwischen das #Ugreen #NAS #DPX2800 gekauft, mit 32 GB #RAM aufgerüstet und 2 #NVNE mit je 2 TB eingebaut.

Azf den beiden M.2 ist #Proxmox im #ZFS #RAID1 installiert. #Homeassistant und #TrueNAS laufen je in einer #VM.

TrueNAS soll nun einen #Datenpool in Form eines verschlüsselten ZFS RAID 1 auf 2 16 TB Festplatten bekommen. So weit so gut.

Nur: Wie bekomme ich die #Daten vom alten NAS, die in einer verschlüsselten #LUKS #Partition liegen, in den Datenpool?

Über #Netzwerk kopieren ist keine wirkliche Option. Das ist für ~ 10 TB Nutzdaten viel zu langsam.

Bitte #Boost für mehr Reichweite. 🙏

Excited for Btrfs RAID1's "preferred read device" feature in Linux 6.14. This allows to have one fast device, example SSD backed bcache device and other slow cheap hard drive. We can set the bcache deice as preferred read device so reads are always fast.
It also wears down only one disk reducing the chance of both the disks evenly wearing out which increases the chances of both of them failing around the same time.

From the pull request:

> more read IO balancing strategies (experimental config), add two new
ways how to select a device for read if the profiles allow that (all RAID1*),
the current default selects the device by pid which is good on average
but less performant for single reader workloads
- select preferred device for all reads (namely for testing)
- round-robin, balance reads across devices relevant for the requested IO
range

Oh boy, setting up this #RAID array is gonna be an overnight ordeal 🤪

Last time I manually set up raid (specifically #raid1) was with two 4 Tb drives. Which I do not recall taking too long; maybe an hour or two. Now I am doing four 12 Tb in #raid5. Good thing I am on summer break 😅

@var it’s nice to have a separate dedicated computer for managing the backup. You really need to have all backup disks attached to SATA. USB is not reliable for backup purposes because is likely to lose data when a sudden power outage occurs. So if you have (for example) 4 disks that all attach to SATA, that is a lot of IO happening, which you really don’t want when you are using your computer for other things that may need that IO, especially games or multimedia. You’ll notice the performance hit if it is backups are happening on a computer that you use for other things.

Also, it’s nice that the NAS comes with software that takes care of things like software RAID-1 or #ZFS for you. Some #NAS products will do #RAID1 in hardware for you.

How I switched us.slackware.nl from lilo to grub

Today I finally switched my US server from lilo to grub as its bootloader.

The reason for doing it now, is that I usually do not have a remote IP console (KVM) to that physical server which is located in a US datacenter whereas I live in Europe. This server's storage is configured as software RAID1

@samurro
I had to ditch LVM. You just can't remove a drive and boot without manual intervention in initramfs.

The complete process is described here: https://dahlem-consulting.de/install-debian-on-raid1

I tried this solution https://serverfault.com/a/1144562 at least the installer goes through without a grub error, but the system still doesn't boot after the installation is through. Installing #debian 12 on a software #raid1 with #uefi seems like a high ask of the debian installer...

@robertdahlem The question is how do I get a raid on my installation partition going. I want to have a #raid1 across two smaller disks where root is installed, the installer now fumbled (grub error) when I tried to do it manually.

I am looking for a tutorial/advice/best-practice on how to setup a #debian server with multiple disks on #ext4. Machine for now should just be used as a fileserver until we integrate the #infrastructure into #proxmox. Still I am unsure how to format the disks. Looking at previous setups we used #raid1 for the root partition and #raid6 for all additional disks. I am just not sure how or where #lvm should come into play...

Struggling to get #fedora #fedora40 server to install with root mountpoint on a #BTRFS #RAID1 file system.

Perhaps it's just not allowed? Perhaps grub can't handle it this early?

Update: I went with a #RAID1 setup. The plan is to have also a #NAS in my #network where I can backup the internal drives to.

Slowly but steady my #Homelab is becoming better and better 😄

Si vous vous demandez comment (et le pourquoi du comment) redonder la partition de démarrage d'un ordi en #raid1 logiciel sous #linux , je viens d'écrire cet article (où j'apprends aussi un truc terrible sur les disques durs récents 😦)
https://mkir.ch/2023-11-05/copier-partition-boot-efi-raid1-linux-mdadm.html

I've made my first modification to the #Linux kernel, ever. 🎉

I have changed the function that decides which drive to read from in a #RAID1 setup in such a way that it always picks the drive that with the shorter queue, which is normally the #SSD code.

This gives me better drive utilisation in my mixed setup of one #CMR hard drive and one #SMR hard drive. Can't really say if performance is better, but the numbers look better.

I just forced one value to be always 1, which is a dirty hack. Maybe I can improve on it and actually turn it into a kernel patch some day. Improving life for everyone! ✨

@hook my recent read on #btrfs #raid1

"In short, the very promise of btrfs-raid1 is an invitation to experience catastrophic data loss: the typical use case is quite a few disks, typically of uncertain origin at best, in a topology that is unusually failure-susceptible."

Acabo de restaurar un RAID-1 que tengo en la laptop del radio shack. Un pequeño conector me permite poner otro disco donde usualmente iba el CD/DVD y entonces tener 2 discos y la posibilidad de tener redundancia. Es de las mejores cosas que pueden hacer y es de las mejores cosas de GNU/Linux #mdadm #raid1 #raid #storage #hdd #discoduro #redundancia #linux

@atoponce
Unfortunately, #md likes to regard single-unit #RAID1 sets as degenerate. (As do, I think, most #RAID systems.) Which I personally consider unfortunate. I would like my Linux filesystems to be on single-unit RAID1 sets, with #LUKS #encryption on top of that, so I can do backups by adding a unit, letting it sync/settle, and then removing it for off-siting.

And I'm not sure where -- or indeed, whether -- #LVM should fit in that design.

🇬🇧 Spring upgrade of home server (homelab) complete.

Shifting from an HP 800 Mini (which I recently sold here) to a slightly larger asrock Deskmini X300 minipc with an AMD Ryzen 7 5700G CPU. The asrock chassis is interesting in that it allows to install two NVMe drives (unfortunately, no hw raid1 for nvme) and two 2.5" drives. I used the latter two slots to install two 2.5" 2 TB drives, which work in raid1

So, can y'all help me raise some funds to get this for MajorNetwork?

Just out of pure curiousity, but does anyone in their #HomeLab have a #StorageAreaNetwork or #SAN for short? I am contemplating setting one up with a few #SBCs or low wattage machines, with all #RAID1 set-up instead of #RAID10 on a single machine.
