En train de tester : cache ZFS en lecture (L2ARC) sur disque nvme. Ça améliore sensiblement les performances sur le desktop notamment au démarrage des fenêtres. Je pense en équiper mon serveur qui tourne nic.eu.org, signal.eu.org, mast.eu.org & al, assez chargé, et y ajouter un cache en écriture+miroir (ZIL). C'est @cquest qui m'avait fait une remarque à ce sujet qui me gratouille depuis. Ça devrait me permettre de prolonger la vie de la carte mère de cette machine, qui dépasse 6 ans déjà.
Avec #ZFS le ZIL/SLOG se prend toutes les écritures (quasiment aucune lecture sauf crash), mais n'a pas besoin d'être volumineux.
J'ai opté pour des #Optane en #3DXpoint qui ont une endurance à l'écriture sans commune mesure avec la flash. On trouve des 16Go pour une dizaine d'euros... format M.2 en NVMe.
Ce n'est plus fabriqué, mais j'ai constitué un petit stock d'avance vu le prix ;)
Weekend project: upgraded our #trueNAS system with #ZFS and a RAIDz1 pool from 4 TB to 16 TB. Easy peasy! #FreeBSD with ZFS was one of the best choices for our NAS. Combined with #restic it is the best backup solution.
Currently I have snapshots going back to mid 2022, which are being pruned according to a schedule, but I've already exceeded 5TB of storage.
I'd like something that'd perhaps slightly less convoluted, but also doesn't break the bank. I'd love to use straight ZFS #replication but that is priced out of my budget.
Going to have to build a #ZFS capable server now to backup too for my #HomeLab . I wonder what OS / Distro I should use as currently the old one is running Ubuntu ? Should I go with #FreeBSD or just stick with what I know Ubuntu ? 🤔
Finally uploaded my first post of the new year to my blog on how I install my #VoidLinux Root on #ZFS setup. If you spot anything wrong please don't hesitate to let me know. 😉
Debian 12 aka "Bookworm" is the latest stable release of the popular Linux operating system. I use Debian's live install image to create a minimal, console-only base configuration using the OpenZFS filesystem with native encryption.
Hatten gestern Nacht ca. 0:48 in #Duisburg wannheimerort #Stromausfall für einige Minuten gehabt. Zum ersten mal hat sich die Anschaffung meiner kleinen #USV für den #proxmox Server gelohnt. Er wurde ordnungsgemäß runtergefahren...
I think I should just give up on suspend to disk when using encrypted #ZFS as I don't use it anyway. It's just one of those things that bugs me. Do it just because it might be possible.
I'm going to encrypt my swap as per the above blog post and remove resume support by adding to my /etc/dracut.conf.d/zol.conf
omit_dracutmodules+=" btrfs resume "
Then I'll reconfigre linux and re run sudo generate-zbm and that will be the end to it. 🙃
I'm so lazy ! I've a blog page to write up on my current #VoidLinux#ZFS#ZFSBootMenu setup with installation instructions / suggestions and suggested tweaks. Yet here I am lounging in a bath. 🙄
Inspired by the example set by @JustineSmithies I'm closing out the year with a Void install on ZFS-Root + native encryption + ZFSBootMenu. :void: :linux:
#Linux#ZFS laptop users do you have any recommended settings that you add into /etc/modprobe.d/zfs.conf ?
Things like zfs_arc_max, zfs_txg_timeout and so on ?
I'm running on a 1Tb nvme drive and have 16Gb ram currently but will get around to upgrading it to it's 40Gb max soon.
Any tips appreciated. 😉
Just in case anyone is interested or better still has some tips on my newly setup #VoidLinux#ZFSBootMenu laptop which is a #ThinkPad Gen 1 P14s AMD with 16Gb ram. But I'll be upgradeding shortly to the full 40Gb. Anyway here is the output of arc_summary and free -h . If I run btop it deducts the arc ram used so without that and running 17 tabs on #Qutebrowser and one foot terminal I'm using 2.62Gb but with free -h it shows as 6.5Gb which obvs is for zfs usage. #ZFS
Thought I'd share a quick screenshot of some of the stats of my newly setup #ThinkPad .
Yes I've used a large swap but that's what I had before and well I can afford the space.
Just got #RiverWM rebuilt from Got on my #VoidLinux#ZFS adventure and looked out of the window to see the sky with oily like clouds. This picture just doesn't do it justice. #Aberdeenshire#Scotland
Well it's booted and I'm in as root for now. I see a few errors on screen there which I can hopefully resolve. Not sure about the "failed to lock /etc/exports.d/zfs.exports.lock: No such file or directory" ????
So all in all I take this as a win as I did expect it to boot first time. I have been documenting my steps though in case I need to redo this install. #ZFS#ZFSBootMenu#VoidLinux
Prepping ready for the big daily driver wipe tomorrow. Making sure I've backed everything up and printing off notes ready for the #VoidLinux#ZFS / #ZFSBootMenu install.
Fingers crossed this will go as smoothly as it did on my test laptop. 🤞 :void:
So this Christmas not only will I be merrily eating and drinking but I've decided I'm going to wipe my daily driver aka the #ThinkPad P14s Gen1 AMD and reinstall #VoidLinux . So this time instead of having an EFI boot partition and LVM encrypted swap and root. I'm going to have the usual EFI boot partition along with an un-encrypted swap partition and a fully encrypted #ZFS partition. Keeping the swap out of the zpool will allow me to use suspend to disk if I ever decided to use it.

@stfn I had a case of a faulty RAM socket in my #NUC — I wasn’t able to confirm it via memtest and I noticed because of stability issues (and random restarts) + #ZFS was reporting mismatching cksums. I tested in one socket at a time and figured which one was faulty (RAM sticks themselves were both healthy). Good luck on your hunt!
Allez zou, mise à jour de ma machine de bureau en FreeBSD 14.0 ! Aucun souci ça a très bien roulé, même avec les graphiques (un reboot de + nécessaire pour vérifier que les pilotes étaient bien configurés).
J'ai juste un problème de taille de curseur de souris sous X. Je n'ai pas de desktop manager, juste un window manager. Si vous avez une piste. #zfs #X11
@masek sicherheitshinweis: empfehle unbedingt den betrieb mit #zfs als mirror und/oder copies=2 mit regelmäßigem scrub cronjob.
ja, ich schreibe aus erfahrung…
Yo you #zfs heads. I'm using raidz in 3 2tb hard drives that is primarily going to be used for media storage. What are all the options I need! Tell me where all the bodies are!.
