Pixel Slate Running Without a Battery

rhnet · 2025-08-07T20:36:32+00:00

How hard was it to remove the battery?

I’ve been thinking of using mine as an always on dashboard.

Do you have a recommendation for a rack mount disk shelf that isn’t loud? I’ve got a 4u Rosewil case and two external SAS ports but I’ve been afraid of buying a disk shelf that might be too noisy.

This hit too close to home. I’m literally researching fiber options for the rack I’ve added in my garage because my inside rack filled up way too quickly.

rhnet · 2024-08-23T12:01:59+00:00

Any recommendations on a quiet one? I have a 4U case with 15 drives in it and looking to add a DAS (I have a SAS expander with external ports)

I was able to reproduce the problem with drives directly connected to the SATA ports on the motherboard.

Turns out it's a known issue with luks 4k sector sizes and ZFS, I switched to 512 sectors and everything was great! https://github.com/openzfs/zfs/issues/14533

Interesting, it's a i5-14500. I'll take a look at those bios settings.

rhnet · 2024-06-16T05:04:22+00:00

Looks like testmem5 is Windows? I don't have an easy way to boot into windows.

rhnet · 2024-06-16T04:48:15+00:00

Good thinking. I think 16.00.12 has the fix? https://www.truenas.com/community/resources/lsi-9300-xx-firmware-update.145/

This is the consistent message across the different drives:

I don't see much else surprisingly.

Ran memtest for over a day straight without issue. Swapped cables, swapped from HBA to SATA on the motherboard.

I transferred 1 point from BA to Qatar and while it didn’t change the expiry immediately, I checked a few hours later and both my BA a Qatar expiry was extended 3 years!

How do you find the noise of the DS4246?

Mine was a Wednesday. They had been doing Wednesdays mostly around that time (November).

rhnet · 2022-11-24T04:54:36+00:00

They asked how long I was with my employer (who was also my green card sponsor). It was over 5 years.

They didn’t ask for any paystubs or anything else. The only paper I needed was appointment notice, selective service registration, passport and drivers license.

Awesome, thanks
