What's the stigma behind using RAIDZ1?

So, I just thought of a related question. If I have the backups, is it better to let the system do the resilver (regardless of the RADZ used) or just re-copy from my backups? If you do have backups of your data, I would still replace the suspect drive and let the system resilver. Resilvering...

It's missing "SMR-Gate".

But still darn true!

Off-site backups are amateur. My backups are off-world.

HP ProLiant ML350 G6 server

Mainboard

(1) Xenon CPU (usage: 0% idle, 15% under full load)

48 GB ECC RAM

(2) 460W Power Supplies in Balanced mode (power draw: 195W idle, 220W under full load)

(original mainboard suffered a power backfeed and caught fire, replaced)

Drive Controller

LSI 9300-16i (16 internal port Host Bus Adapter)

Storage

HP SFF box with 8 SAS hot-swap bays (OEM)

Boot: (3) HP SAS HDD (300 GB 10.0K RPM (triple mirror)

Snapshots: Seagate SAS HDD (2 TB 7.5K RPM) (not nearly enough storage, will upgrade)

Data

8-drive RAID-Z3 (24 TB usable storage)

LFF 5-bay box stuffed with 6TB HGST SAS drives, (1) Noctua NF-P12

LFF 3-bay box stuffed with 6TB HGST SAS drives, (1) Noctua NF-A8

Backup: Buffalo TeraStation (x2) (not nearly enough storage, will upgrade)

Offline Backup: Eddie Van Halen drives (also not nearly enough storage, will upgrade)

UPS: APC RT 1500, freshly reloaded with new Pb packs.

TrueNAS SCALE 22.12.0 (awesome)

DETAILED HARDWARE AND BUILD NOTES (resource)

Link: Resources List (help)

TrueNAS is not as simple as videos make it look, though it is fairly easy to get a system running if you read the documentation and don't color outside the lines. Click the above link for a list of resources and help with how to do things in TrueNAS.

I sourced most of this from @Dice, it's too funny to not share.

anodos:
You need to change your problem so that lines up with my solution.
Ericloewe:
We're talking catastrophic PSU failure, massive undetected RAM failure, physical destruction, alien high-intensity degaussing beams, extreme heat or the presence of Linus from LinusTechTips in the same room as the server.
GrumpyBear:
Though the fans are rated for 800-1500 rpm (downhill, with a tail-wind, and a moon in the third phase of Venus and with 64-byte UDP packets)
joeschmuck:
I guess I could ask my Ex (she works for HGST) for some discount drives but they may be filled with C4 vs Helium.
DrKK:
you have Seagate Barracuda ST3000DM001. The correct storage configuration with this model hard drive is as deep in a landfill as possible.
DrKK:
OP, just for the record, having a "4 drive stripe", on a scale of ZFS stupidity from 1 to 10, is a 9.998, behind only having a "5 drive stripe". I hope that every byte of this data is either disposable, or is well backed up, sir. No offense; we care more about your data than your feelings. :)
Ericloewe:
It's actually using very advanced quantum sorcery, but since Unix is Unix, everything gets dumped into the decidedly classical standard output, so that people can do Unix things to it like "pipe it through SSH" or "pipe it into a file" or "pipe it straight to zfs recv" or "pipe it into cat and immediately get arrested by the Unix police because why the !%#& would you use cat to view a text file, much less a zfs replication stream".
Black Ninja:
My bad experience with Seagate stopped immediately after I stopped buying them :)
WI_Hedgehog:
- ZFS eats RAM like a fat man at an all-you-can-eat fried chicken buffet.
- I'm perhaps abnormally risk-adverse because I come from a Windows Server environment where the motto is, "If it ain't broke, it will be."
- Complexity killed the cat--#1010b times!"
- Why, for the love of God, did you buy hardware before you started asking questions????

ChatGPT: RTFM.
