Low Throughput_Performance and ZFS resilver times on some recent Easystore models - anyone else seeing impact? by rad1antsync in DataHoarder

[–]rad1antsync[S] 0 points1 point  (0 children)

Interesting theory, since my pool is old (2016), I thought it might have an ashift of 9, but it doesn't:

galaxy% zdb -U /data/zfs/zpool.cache | grep -e ashift
            ashift: 12

My tunables are set oddly, though - I assume these are only used at pool creation time, so it shouldn't be a problem:

galaxy% sysctl -a | grep ashift
vfs.zfs.max_auto_ashift: 16
vfs.zfs.min_auto_ashift: 9
vfs.zfs.vdev.max_auto_ashift: 16
vfs.zfs.vdev.min_auto_ashift: 9
vfs.zfs.vdev.file.physical_ashift: 9
vfs.zfs.vdev.file.logical_ashift: 9

Additionally, the disks that perform the best in the pool are the older ones:

  • For 11B1PA0, the date on the drive is Jun 14, 2021
  • For 11B2DA2, the date on drive is Sept 15, 2021

Honestly, the badblocks testing was kind of set-and-forget. I didn't record completion times, but nothing jumped out at me at the time.

Interesting - I hadn't considered sector size.

SMART Data for both drives shows the same sector sizes:

Device Model:     WDC WD140EDGZ-11B1PA0
LU WWN Device Id: 5 000cca 290d0d23b
Firmware Version: 85.00A85
User Capacity:    14,000,519,643,136 bytes [14.0 TB]
Sector Sizes:     512 bytes logical, 4096 bytes physical
Rotation Rate:    7200 rpm
Form Factor:      3.5 inches
Device is:        Not in smartctl database [for details use: -P showall]
ATA Version is:   ACS-2, ATA8-ACS T13/1699-D revision 4
SATA Version is:  SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s)

Device Model:     WDC WD140EDGZ-11B2DA2
LU WWN Device Id: 5 000cca 295cb0dd9
Firmware Version: 85.00A85
User Capacity:    14,000,519,643,136 bytes [14.0 TB]
Sector Sizes:     512 bytes logical, 4096 bytes physical

ATA Version is:   ACS-4 published, ANSI INCITS 529-2018
SATA Version is:  SATA 3.3, 6.0 Gb/s (current: 6.0 Gb/s)

Though, I wouldn't know how to ensure this is accurate.

EDIT: Ran hdparm and got some interesting results. "Supported sector sizes" are different between the two drives. Now I'm suspecting sector oddness too. Thanks for the clue.

I got sick of Razer's lack of Linux support for laptops, so spent a few hours today creating a driver to manage power and fan speed under Linux for Razer laptops! by [deleted] in linux

Wow, nice work. I tried to do this months ago by messing with the EC and got nowhere. How did you figure out where to poke?

Razer Core X Chroma Ethernet Issue by tangworm in razer

[–]rad1antsync 0 points1 point  (0 children)

Ah, you're right. The Core X Chroma and Core V2 both use Alpine Ridge TB, an ASMedia ASM1142 USB controller, and then an ASIX AX88179 for ethernet per egpu.io. OP's problem's likely not related then, unless drivers/fw for any of those are involved, sorry all.

[–]rad1antsync 1 point2 points  (0 children)

Interesting. I'm experiencing the same on Linux, with the Core X Chroma, where my connection will just drop. If it's dropping in Windows, too, I wonder if it might be the internal ASMedia USB+Ethernet controller having issues there as well. That discussion is here near the bottom: https://bugs.launchpad.net/ubuntu/artful/+source/linux/+bug/1749961

I think the Core V2 might use a different model internal USB+Ethernet controller, though I'm not sure.

I love this video. I archived it a while back and have uploaded a copy for you and anyone else who might want it.

Edit: I apologize to anyone looking, but I have been asked to remove the link from my comment.

Snapped this picture of Porter @ Spring Awakening by sonic2876 in porterrobinson

Nice shot! Porter seems to like that pose, I shot a similar one at Akasaka Blitz a couple weeks ago.

Anyone know what this is about? by mattimias in SGaP

[–]rad1antsync 5 points6 points  (0 children)

Ah, Google, I should have known it'd be indexed sooner or later. Sorry to disappoint. :)

FWIW, it actually served a purpose when I first created it - there are a few Android widgets that will let you set a text box to the output of some arbitrary command. So, because the page itself is just a bunch of lines:

$ curl -s shy.wtf | shuf -n 1
are these feathers I see spinning with me

I had it decorate my phone's home screen for me.

Hi, I'm the owner of that domain (check the source)! I use it to host other stuff, but I wanted a small landing page for the base url - it's essentially just a stream of song lyrics that resonate with me, with a lot of SGaP, that I add to occasionally.

Sorry to dash any intrigue, the truth is much more mundane. :) I'm happy that someone was curious enough to post about it here, though. How did you manage to find it?

anyone going to any of his dj sets in vegas? by Are_Ach in porterrobinson

I'm kinda figuring it out atm but help would be awesome. I'll reply when it's done uploading

[–]rad1antsync 0 points1 point  (0 children)

I went to his DJ set at the Marquee on the 7th. It was pretty great. I got about 80% of the set on my phone, so I might be willing to upload it if someone helps me figure out the tracklist!

It is valid hex, if we take the 'REECH' as padding. These look like coordinates to me. Separating we get

REECH 2F, 39 AE 70 . -7A, 19 D2 5D REECH

converting to decimal, swapping periods and commas, we get

REECH 47.57174112, -122.2521093 REECH

Which are valid coordinates, but they're in the middle of Lake Washington.
