Whats next?
I have found that smartctl(8) version 7.2 has trouble decoding some
of the statistics for my Intel SSD 520 Series drives (Debian
Stable), while smartctl(8) version 7.3 does a better job
(FreeBSD-12.3-RELEASE-amd64). So, perhaps you are seeing bad
information from smartctl(8) version 7.2.
Debian backports does not seem to offer smartmontools 7.3.
Debian Testing and Unstable have smartmontools 7.3.
Alternatively, Samsung does make software tools for their storage
products. Unfortunately, I believe the tools are Windows
applications; so, they require a Windows installation.
Have you tried smartmontools 7.3 and/or Samsung tools?
smartmontools is A: not found, but synaptic says 7.2-1. And B: no,
synaptic won't let me fiddle with that.
AIUI you have a HBA/RAID card in that computer. I suspect that you
also have USB devices and/or other connected hardware. What happens
if you disconnect everything? If the problem goes away, do a search
and find the problem hardware.
Not a raid card, just another $20 6 port sata card, its software
raid. There is no drive activity
of any kind when it hangs. The only indication of life at all is a
row of color changing leds on
the front edge of the mobo are cycling the colors, possibly a little
slower that they are right now.
I assume you understand that expansion cards can have extension
firmware that runs during POST, which can delay or halt POST (?).
Similarly, the motherboard firmware goes through a USB enumeration
process during POST and connected USB devices must have compatible
firmware; issues can cause delays and/or halt POST (?).
Does the boot process change when you disconnect all of the drives?
When your remove the card? If so, use a process of elimination to
find the problem item(s).
I've considered that disconnect as my usb tree looks like a 50 yo
weeping willow.
Everything but the keyboard and mouse buttons can be disconnected by
about 6 usb cables.
Getting these 88 yo knees down on the floor to see about plugging
them back in is a
bit of a chore so they don't get disconnected very often.
That is why they invented knee pads and/or (great?) (grand?) children.
Does the boot process change when you disconnect all USB devices and
connect the keyboard directly to the motherboard? Different ports?
Different keyboards? If boot changes, use a process of elimination to
identify the problem keyboard(s), port(s), and/or USB devices(s).
This is the main computer of a 7 machine home network that by the
time they are done arguing
about who won next Teusday's election, might have 4 more bannana pi's
to connect to.
I'd like to have bought rpi4b's w/8G's but their scarcity has ran the
price above $300.
Much newer bananna pi's BPI-M5's with 4G are $90. And have faster usb
as all 4 ports are usb3.1.
Do like I did with the rpi4b running my biggest cnc lathe, and move
all the high traffic stuff
to a $30 SSD and get uptimes in years. I have an automatic 20kw
standby and the pi has a small
ups. That made the pi into a workstation, building its own real-time
kernel AND linuxcnc from a git pull if
the buildbot at linuxcnc.org gets a tummy ache.
All the more reason to figure out why the server is misbehaving and
fix it.
