#sata

4 posts4 participants0 posts today

Since I started to use the #debian kernel instead of an #armbian legacy kernel on my #RockPro64 I had a few crashes. Most of them seemed to have been related to #sata, because they stopped after I exchanged the sata pcie with another one of the same type.

I had another #oops afterwards and decided I should look for a #watchdog to reboot the system in case of trouble.

After reading a bit about watchdogd the most simple solution I found is:


root@TEST:~# cat /etc/cron.d/watchdog 
@reboot   root wdctl -s 180 
* * * * * root echo "1" > /dev/watchdog

I'm testing it on a non-productive board and it seems to be good. It works for a forced oops echo c > /dev/sysrq-trigger and if I stop cron.

But it doesn't work in the state after a simple halt: the system tries to start and hangs after showing the first line of u-boot output.

Die Bandbreiten scheinen zu stagnieren, beim Internetzugang, bei USB/TB, im (W)LAN, sogar bei einigen PC-Schnittstellen. Im Podcast diskutieren wir die Gründe.

Follow-up to this note:

At one of the times the current #Armbian #linux kernel didn't crash, but booted on my #RockPro64 I installed #GotoSocial and yes: no more strange error messages running it. The only time I remember that I updated a linux kernel to make an application work.

Preparations to get the production system running with the newer kernel:

  • in case of problems I'd need to know my way back to boot the old kernel: u-boot recap and learning
  • test suspected problems with the #sata #pcie ctrl beforehand (get a second Pine64 sata ctrl for the test system)

Meanwhile Dragan had patched the device tree and asked to check on a few reboots whether this would make a difference or cause any regressions.

Further down the #RabbitHole the tunnel forks…

Chris Vogel's microblogNoteFollow-up to this note: I decided to test...

I've never been fond of #JMicron #USB bridges! #SATA or #NVMe! (#ASMedia ain't much better?)

It's just a pain in the rear to pull #SMART reports off the drive!

NO, i friggen DO NOT WANT TO fumble around with "-d", and quirks, and shiz!

Tools on friggen #Windows (#CrystalDiskInfo) CAN DO it, so SHOULD smartmontools on #Linux, automatically!

(back in the 480mbps USB 2.0 days - things were BETTER - current #Linux code hasn't caught up)

…or is it #Firmware?

Here's an odd question. Is it possible to daisy chain hard drives? Like, can I use one SATA port with a ribbon that has connectors for two hard drives. I think this was possible on my old IDE computer, but no idea with modern hardware.

I want to dual boot, and all the suggestions are a drive for each OS, but my laptop has very little physical space and all of the SATA ports are filled. That said, I might be able to shove a small M.2 SATA drive in there. I asked on the hardware company's forum and they were less than helpful.

Still looking into building a #computer in the next few months, though I'm waiting for situations to change a little before I commit to anything.

Looking at various #motherboard options, specifically those with a 120 Watt #AMD #AM5 #CPU Socket so I have a good upgrade path. Right now I've gotten it down to a few, but I notice that some of these have multiple #M.2 #SSD slots, and while I do plan to have one of them, I would like the option to have an #HDD, due to the cost-to-storage ratio.

So I'm wondering, is there a way to put a #SATA drive in an #M2 slot? I'm sure someone has made some sort of adapter...

The nodes themself also came out a lot cleaner, left them in there for months longer than I previously had between cleanings. And it shows well on the last photo where I only cleaned half of the #USB<->#SATA #SSD adapter. This probably means I only have to clean them twice a year. And once the enclosure is fully done, only once a year 🎉

This weekend I learned that #NAS systems like #TrueNAS are less limited by network bandwidth than by their #SATA backplanes. I'm only getting sustained SATA speeds of 400 MB/s over a 10 Gbps link when running unquantized #LLM models. That's unusable.

I'd expect a 10-wide RAIDZ2 vdev to provide better read performance than that, but apparently not with my current setup. I'm not yet convinced that an #iXsystems SATA enclosure would do any better.

I think that #CAMM is a bad design compared to #SODIMM & #DIMM...

Still, just gimme regular-ass socketed Chips & #DIMMs ffs!

  • Also we don't need to make the THINN-nest machines ffs - just make them #repairable and #serviceable and #upgradeable, because #AntiRepairDesign is way more unsustainable than the 0,1% of idiots who give a shit about whether their #DDR5-RAM can do 6400MT/s or 4800MT/s, simply because most users won't notice that at all (unlike switching from a 2,5" #SATA-#HDD running at 5400rpm to an #NVMe-#SSD that maxes out #PCIe 4x connections.

#FACT: #RAM & #SSD|s are inevitably dying due to age and use and like #ThermalPaste need to be #replaceable for a device to work longterm!

I'd rather have a #THICC af #laptop that actually survives my daily use than some flimsy #tablet that snaps in half if I sneeze at it.

  • No seriously, most devices can't even fit proper ports and cooling fans for no good reason whatsoever!

Also I think it's insulting to frame basic things like "stability" as a negative.

@alterelefant @Heidi As of now, we can see stuff like the #ExaDrive, a 100TB 3,5" SSD for #online - #archival storage.

  • As #Helium-filled #SMR-#HDD|s struggle to meet the demand for storage at an acceptable thermal & power envelope and price, #SSD|s will inevitable take over as not only the more robust media but also cheaper, more dense and easier to use.

As for the #NeoFloppy that thing could be made - I'm just not good enough layouting PCBs with the precision needed for #PCIe signalling...

  • Needless to say if constant write speed and lifetime in writes is secondary, then a stack of cheap #SATA-SSDs already beats #LTO-9 tapes unless you need to backup literal #Petabytes and need the fancy features like #WORM media.

That being said, it's inevitable that even WORM as a feature may be copied over.

  • In fact #ZFS can already offer many features of #LTFS, including read-only snapshots and thus append-only #archives.

Until there are #COTS solutions tho, LTO #Tape and other options will OFC remain dominant and relevant.

  • Still I'd happily see storage vendors take up the NeoFloppy and build something off it.
