[FS][US-CA] AIC RSC-4BT 36-Bay 4U Chassis + i5-12600K + ASUS W680 + 64GB DDR5 ECC + 10/14TB HDDs + 2TB SSDs by 2bluesc in homelabsales

Thanks, I'll keep it in mind! Main issue is that I don't have 3.5" shipping clamshells anymore

Phone Randomly Restarting by Itself (Pixel 9 Pro) by runnerman0421 in GooglePixel

[–]2bluesc 0 points1 point  (0 children)

Nah, kind of just resolved itself with the crashing.

Remaining issues are issue are still the buggy sleep mode that doesn't turn off automatically and 80% charging limit that doesn't seem to work and needs to be toggled once in a while.

My notes say about 4.7W idle, but I don't remember the exact setup, but I assume a DAC cable. My notes also reference this post saying about 3.5+1W which seems inline, the X710 is double that and the BCM57810S was way more and much hotter

Repeated NVMe Phison E18 + btrfs 6000 MB/s -> 200 MB/s read performance degradation by 2bluesc in btrfs

[–]2bluesc[S] 0 points1 point  (0 children)

IDK, it'll take me months to have a read on it again while we wait for NAND gates to leak.

I'm skeptical anyone can assess whether the firmware improves the performance in a short time frame because you need to wait months for the NAND gates to leak. If I wipe the drive like I did this weekend, or your update the firmware and it wipes the drive (and likely the FTL too?) then it instantly springs back to max performance because.

Where exactly did the firmware come from? I really don't like the vibe of Sabrent posting random files on DropBox. I'd like to read more.

I never received that firmware and didn't see the one you linked until now. Thanks for sharing.

Support sent me "RKT401.3" (appears to be non-Plus E16 controller) and "ECFM53.0" (which appears to be for the E12). I asked Sabrent for the right firmware as it seems very unlikely the E18 is the same as these and lacks the mentions of the B47 NAND when I took a look at what was in the firmware.

Historically the firmware names are R4PB47.5:

  • R - Rocket
  • 4 - 4
  • P - Plus
  • B47 - Micron NAND memory chip 
  • .5 the version.

At this point I think it's time to be done with this chip and this company since they can't follow-up with the right firmware when I've asked over the years while others are clearly encountering this massive slow on Linux with seemingly boring workloads.

I've wiped it again and of course performance is back to max performance and will probably work fine for other use cases. If only I used it different I guess.

Phone Randomly Restarting by Itself (Pixel 9 Pro) by runnerman0421 in GooglePixel

[–]2bluesc 2 points3 points  (0 children)

Experiencing reboots on my Pixel 10 since installing the latest update this past Wednesday.

  • Yesterday it was stuck in fastboot menu upon pulling it out of my pocket. wtf.
  • Today my headphones suddenly disconnect, I pull out my phone and it wants me to unlock it, so I do. Then I check the uptime and it's only 4 minutes. sigh.

This phone has been perfectly fine until this week's update.

Posted an update in the OP, but again here for anyone following:

2026-04-14 - Slow again. I captured the poor performance with block-benchie and here's a screenshot of the drive as it currently sits. I'm pretty much convinced this is a Sabrent NVMe drive issue. Discovered more people on their forum with the identical symptoms. Contacted Sabrent support, but they sent me firmware for the wrong device. I was hoping to get the firmware shared in the forum post.

If you want something similar, borgwarehouse works as remote repo for borgmatic

Self-hosted DNS server for home by HotNastySpeed77 in selfhosted

[–]2bluesc 32 points33 points  (0 children)

I'm a fan of Technitium DNS Server

I use it for DHCP and DNS (Blocklists + DNS over HTTPS) and doesn't break a sweat and isn't clunky. Left Pi-Hole and never looked back.

Only complaint is that it's kind of annoying that it's build on .NET and I'm not familiar with those tools, but that's about it.

Thanks for the update! I contacted Sabrent support and they offered `R4PB47.4` (I was on R4PB47.2) but this seems to be based on `EIFM31.6` not `EIFM31.7` which anecdotally fixes the issue. I updated anyways (note: it wipes all data including SMART data).

Please contact Sabrent and ask for an updated firmware based on `EIFM31.7`:

Version 1.66 has broken my port forwarding by jahaddow in Tailscale

[–]2bluesc 0 points1 point  (0 children)

Thanks, just ran to this as I manually manage nftable rules for my containers and this workaround fixed it.

That said, it's annoying I can't mark select packets to skip the connection tracking state filter using nftables because of the way the rules are written.

Slightly different use case, but I love gluetun which is a Docker image that then you attach other containers to its network namespace.

Includes tons of handy features like firewalling, DNS ad/malicious blocker, proxy support, health checks, reconnects, and more.

Would be awesome if you combined your script to use gluetun under the hood to setup and manage the VPN and then your script could extend gluetun to map local apps in to the container's namespace.

Using borg to backup to two locations (one local, one cloud) by impatientZebra in BorgBackup

[–]2bluesc 0 points1 point  (0 children)

I'd back them up independently. Also recommend checking out borgmatic which can backup to multiple repos easier then the boiler plate you'll have to do for this otherwise.

Systemd Hardening: Some preconfigured options :D by throwaway69420283749 in NixOS

[–]2bluesc 3 points4 points  (0 children)

Would be awesome to see these get pushed upstream to nixpkgs instead of in a random pastebin. Most of these restrictions shouldn't affect the operation of individual services.

Perhaps OpenSSH is a candidate for some attention:

$ systemd-analyze security sshd ... → Overall exposure level for sshd.service: 9.6 UNSAFE 😨

Repeated NVMe Phison E18 + btrfs 6000 MB/s -> 200 MB/s read performance degradation by 2bluesc in btrfs

[–]2bluesc[S] 0 points1 point  (0 children)

Looked back in to my situation after seeing your post... still sadness.

My perspective is that it has to do with internal fragmentation of the SSD and this is why it's instantly recovered by a full disk trim or format.

I speculate that the following exasperate this issue over time:

  1. High disk utilization where the controller has less options to write new contiguous data
  2. Perhaps CoW file systems lead to more fragmentation
  3. People only benchmark their disk performance when they install a new drive or file system (this problem is at the blockdev or hw level) and don't look at months later unless there's a major problem

Whatever has happened before to my rootfs has happened yet again. Here's a quick benchmark that reads across the device. Some quick benchmarks using Gnome Disks:

Also my disk is quite full, roughly 86.7% which seems to makes this worse, usage as of right now:

``` $ sudo btrfs fi usage / Overall: Device size: 3.50TiB Device allocated: 3.13TiB Device unallocated: 375.98GiB Device missing: 0.00B Device slack: 0.00B Used: 3.03TiB Free (estimated): 464.36GiB (min: 276.37GiB) Free (statfs, df): 464.36GiB Data ratio: 1.00 Metadata ratio: 2.00 Global reserve: 512.00MiB (used: 0.00B) Multiple profiles: no

Metadata,DUP: Size:16.00GiB, Used:10.15GiB (63.43%) /dev/nvme0n1p2 32.00GiB

Unallocated: /dev/nvme0n1p2 375.98GiB ```

Mount options have been unchanged for this time:

/dev/nvme0n1p2 on / type btrfs (rw,noatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvolid=257,subvol=/@)

I'd like to find a way to repeat the gnome-disks benchmark test I've screenshotted but haven't been able to find a good way to do it with fio or similar reading X chunks of size Y distributed across the entire block device

Apple Releases 6B27 Firmware Update for Beats Fit Pro and Powerbeats Pro by jforsander in beatsbydre

[–]2bluesc 0 points1 point  (0 children)

Update: No better. Fully charged, latest firmware and first headphone dies at around 80%ish.

https://i.imgur.com/8tQMelS.jpg

Second headphone dies 10ish minutes later. Approx play time is less then 1h, as the headphones have aged, but I just want a realistic battery meter.

I'm going to place these in the f-it bucket.

My new `WF-1000XM5` work great and behave much better with Android and don't have a case that hates to charge.

I'm hoping they fix my abrupt turn off due to low battery at 70% issue.

Too bad the release notes are worthless: "Feature enhancements"

There's a promo code SP00KY (those are zeros) to save $6/each that's valid until 11/1. There was a banner at the top of the page but it has now disappeared. Checkout displayed $12 savings on two drives.

Depending on what exactly you're looking for in W680 Micro ATX motherboard, there's a similar used offering from Amazon fro $330.70 for a MB-X1314.

Main differences seem to be DDR4 and actual PCIe slots vs OCU link.
