When I set up my NAS (running Fedora Server 44) I fell into the same trap as @VileLasagna; I used ZFS so I'd get proper RAID across my disks.

Not that I could afford to replace one if it dies. Thanks AI techbros, I love it.

Anyway, I'm stuck being unable to "dnf upgrade" the system because I'm waiting for zfs to catch up with the kernel. 😓

Установка Arch Linux на ZFS

Привет! Меня зовут Денис, я 3D-художник и Linux-энтузиаст. Более 8 лет Arch Linux является моей основной и единственной операционной системой. Сегодня хочу рассказать об установке Arch Linux на ZFS. Почему ZFS? Однажды я решил собрать stripe (RAID0) на ноутбуке с двумя дисками. Хотелось сохранить привычную структуру директорий и не думать о том, на каком диске что лежит. На тот момент я уже использовал ZFS на файловом сервере, а на ноутбуках - Btrfs + LUKS2. Загрузить Arch Linux с RAID на btrfs у меня не получилось. С ZFS, напротив, не возникло никаких трудностей. Задача:

Arch Linux на ZFS для людей: новый TUI-установщик archinstall_zfs

Установка Arch Linux на ZFS всегда была не очень тривиальным делом: нужно знать много тонкостей, прочитать кучу статей и различные вики, разобраться с флагами создания датасетов и пула, с конфигурацией initramfs и с тем, какие systemd сервисы стоит включать, с параметрами командной строки ядра и правильными конфигами. Если ставить вручную, то установка занимает целый вечер, с вдумчивым раскуриванием мануалов перед черной консолью. А можно ли проще?

Is #zfsonlinux a good idea?

I am quickly realizing that a 2x 1TB mirror ZFS pool does not, in fact, give me a whole lot of space (rather, only 1TB of it, how shocking). Confronted with the realization that I do actually have more than 1 TB of data I'd like to put on the pool, I need to expand my ZFS array.

How should I go about doing this?

I have another old (08/'15 with okay stats) 1TB drive laying next to the server, and a 3TB drive that I can probably shovel stuff off of. Should I make another vdev with the 1TB + 3TB drives in another mirror I guess? I hate to waste that space, but I don't have the money right now to buy drives / a proper server. I would upgrade to Raid-Z1 and make it 3x 1TB, but that's not possible. So I think another mirror vdev of 1+3TB is my best choice right now, and then later down the line when I get a job I build a *proper* server with actual/better/larger drives and transfer it (*the whole pool) over.

Sound like a plan? Thoughts?

Домашняя лаба. Как собрать домашнюю инфраструктуру мечты

Мой первый опыт на Хабре получился не очень положительным, и, признаюсь, до сих пор смотря на комментарии и оценки, мне стыдно и больно где-то внутри. Потому в имя исправления ошибок молодости решил написать серию статей о том, как дома собрать свою "идеальную" хранилку, или сервак, или мини облако. Поделюсь опытом, своими знаниями и пониманием, а также мыслями, которые могут помочь выполняя похожую задачу для себя.

#ZFS on #Linux observations:

1. ZFS on #Solaris is awesome.
2. My experience with ZFS on Linux has been terrible.

I'm using a Dell #R720 configured as a NAS server, with a Dell PERC H310 controller that natively supports JBOD, running Gentoo Linux. The Dell replaced a succession of two SunFire X4540s, both of which were absolutely rock-solid as NAS servers (until their system controller boards failed) and never once had a ZFS error reported except when a drive physically failed. With the R720, I get hot and cold running errors reported. I'm using all Samsung 870 Evo solid-state drives, in two #RAIDZ arrays, one of eight drives and one of six. I am at this very moment in the process of cleaning up the arrays ... again.

What I can't figure out is why.
— Is ZFS on Linux really that terrible?
— Does ZFS on Linux just somehow not work well with SSDs?
— Does the PERC controller in the R720 not work well with SSDs?

I wasn't originally running SSDs in this array; my first attempt was using 2.5" spinning rust drives. I rapidly discovered two things:
1. As far as I can determine, all 2.5" mechanical hard drives 2TB or larger on the market are SMR drives;
2. OH MY GOD, SMR DRIVES (especially, I am told, in ZFS) ARE UTTERLY FUCKING HORRIBLE except on WORM (read once, write many) applications in which you don't really care how slow the original write is. RAIDZ write performance on the Dell on brand new 2.5" SMR drives was four to six times slower than RAIDZ write performance on the X4540 with older and slower CMR drives on older and slower SCSI/SAS controllers. Despite newer, "faster" drives on a newer, faster controller, the SMR array was utterly unusable.

Now, I'm not experiencing any problems with SSDs in any of my other systems, Windows or Linux, INCLUDING the R720, except with ZFS. The boot drives on the R720 are an mdraid mirror formatted XFS and have never thrown a single error.

So this is really leading me to wonder a crucial question:

Is there something I don't know about #ZFSonLinux that causes it to not work well with #SSD drives? Do I need to just forget about running ZFS on my NAS and let the PERC controller create hardware RAID5 volumes?

(And if anyone wonders "why don't you just run a commercial NAS appliance?", well, I tried that route. I tried one of the very latest generation QNAP servers that run ZFS storage on a Linux OS. Oh my god, I can't even begin to speak to how horribly bastardized it was. QNAP may well be a good NAS choice if you only care about Windows and SMB and never ever want to look under the hood or try to accomplish anything except through the web front-end, and don't already have an existing backup solution that you want to continue using.)

Oooof. While poking at how best to install ProxMox with ZFS, I discovered one of the disk pools on my fileserver has two disks...but isn't a mirror. 😱 Now to scrounge through spare disks to see if I can push the data off it to rebuild into a mirror...
