Thanks Paul - that's how I've set it up, and yes, if I run the command a
second time, it returns 0 bytes.

But wait - I don't recommend updating to the firmware that I've used for
the moment.  The read and write speeds seem to have dropped to the same
as the older SATA adapter+drive, i.e. the 50% boost has gone, despite
still using UAS.  Something else must have changed!

That first large unmap will happen only the first run after boot.  After
that it will only be the bytes that have changed since the last unmap.

So I would run a trim even (in the background) shortly after booting
your device.  Then on a weekly cron job.

Re: [SlimDevices: Unix] [How To] Using the Argon One case for the Pi 4B together with piCorePlayer (7.x)



Success!  With the 'unmap' provisioning mode made persistent by
following Paul's guidance for editing bootlocal.sh, I can now issue the
fstrim command after a reboot.


Code:

tc@pCPServer:~$ sudo fstrim -v /mnt/Music
  /mnt/Music: 45572067328 bytes trimmed



Just need to set up the cron job now.

That figure of 45572067328 bytes seems to be exactly equal to the amount
of free space on the drive.

This seems to be the key.  I downloaded the 141126_A1_EE_82 firmware
(from 'here'
(https://www.station-drivers.com/index.php?option=com_remository=353=startdown=4053=en)),
and the zip file includes a Windows executable to flash the firmware. 
The executable also tells you what version is already on the device.

It told me that the old SATA adapter (which supports trim with my
Sandisk SATA SSD) is (was*) at firmware 141126_A1_EE_83, whereas my new
Argon 40 M.2 SSD adapter was as 140704_A1_00_00.  If the lower number
corresponds to an earlier version, it seemed possible that an update to
a higher number might enable trim.

So I took a brave pill and decided that if I bricked the adapter then
I'm only out £18.  I updated the M.2 adapter to 141126_A1_EE_82.  (Note
that the update will FAIL if there's a disk drive attached - this is
what I tried first, because detaching the drive requires a small amount
of disassembly, and I was being lazy). 

Now when I inspect the adapter+drive as before under pCP I see:

Code:

tc@pCPServer:/mnt/sdb2/tce$ sg_vpd -p lbpv /dev/sda | grep Unmap
  Unmap command supported (LBPU): 1

  and

  tc@pCPServer:/mnt/sdb2/tce$ sg_vpd -p bl /dev/sda | grep unmap
  Maximum unmap LBA count: 4194240
  Maximum unmap block descriptor count: 1
  Optimal unmap granularity: 1 blocks

So now it looks as though the adapter supports trim and I can press on
and enable it.  It's odd that the Argon M.2 adapter, which I purchased
~18 months after the old SATA adapter, should have an apparently older
firmware.  I hope the update hasn't broken anything else, because I
can't find the 140704_A1_00_00 version to revert it. 

*I 'accidentally' loaded the 82 firmware over the 83 version that was
already on my old SATA adapter, so now of course I'm worried what
feature was added/fixed in that single digit increment!

If you read the threads, the Asmedia adapters are going to be dependent
on the firmware loaded on the adapter.

It doesn't surprise me that the M.2 drive is faster though...

It doesn't.  Both drives show up as identical devices with identical IDs
(is that possible?), and both are using the uas driver.

So given that unmap is supported by the old Sandisk SATA drive on what
appears to be the same adapter, the fact that it's not supported on the
new Western Digital M.2 SATA drive is unlikely to be the fault of the
adapter.

Thanks again Paul.  So it appears that the M.2 drive is using UAS after
all:

Maybe this explains why it is 50% faster than the previous SATA SSD -
I'll have to go back and recheck that one.

I did load the full Raspberry Pi OS onto a spare SD card and I got the
same '[Unmap command not implemented]'.  SO I starting to doubt what the
Western Digital Dashboard told me about Trim under Windows - I'll take
another look.

Ok, then I don't have to change to the M.2 SSD. It would also be a bit
expensive, as I am using a 2TB SATA SSD.
The longest operation is to create the LMS library completely new and
that is really fast since I changed the USB stick used for the database
(I think it is 30 minutes faster now). It took 48 minutes for ca. 85000
songs.

Re: [SlimDevices: Unix] [How To] Using the Argon One case for the Pi 4B together with piCorePlayer (7.x)

My M.2 SSD and adapter have arrived, and I've been investigating with
the tools described in the 'blog post that Paul linked to'
(https://lemariva.com/blog/2020/08/raspberry-pi-4-ssd-booting-enabled-trim).

I first of all investigated my existing Sandisk SATA SSD drive that's
connected via a cheapo SATA-to-USB adapter. The indications are that
it's unmap-capable (but not enabled), and that it's using 'Bulk-Only
Transport' (BOT) and not UASP. No great surprises there, and I guess I
could implement unmap as per the instructions in the blog post.

Code:

tc@pCPServer:/mnt/sdb2/tce$ fstrim -v /mnt/Music
fstrim: FITRIM: Operation not permitted

tc@pCPServer:/mnt/sdb2/tce$ sg_vpd -p bl /dev/sda

I then used the same commands on the new 'M.2 SATA drive'
(https://www.amazon.co.uk/gp/product/B078WYS5K6) connected via the Argon
adapter. If I'm reading the output correctly, then this setup is NOT
unmap-capable, and is also using the BOT driver, rather than UASP.
That's a bit of a surprise, given the blurb on the 'Pi Hut page'
(https://thepihut.com/collections/raspberry-pi-cases/products/argon-one-m-2-raspberry-pi-4-case)
about UASP support. Perhaps I need to do something to enable it, or
perhaps I'm misreading the output.

I also did a few rudimentary speed tests, as per the instructions on
'this page' (https://elinux.org/RPi_SD_cards#Terminal_Commands).

I found that my old SATA drive achieves a write speed of around 150MB/s
and read speed of around 210MB/s.
The new M.2 SATA drive achieves a write speed of around 245MB/s and a
read speed of around 300MB/s.

These are all somewhat short of the 5Gbps possible under USB3, but hey,
at least the new M.2 drive seems to be about 50% faster than the SSD
I've been using. And since it's only used to store a largely static
music collection, both drives are more than fast enough.

I agree!  The case seems extraordinarily effective without the fan. 
I've yet to test the fan at higher temperatures, but it doesn't seem to
be particularly useful at lower temperatures - when the CPU is sitting
at 40 degrees, if I turn the fan on to 100% it barely drops the
temperature by one or two degrees.  It may be different when the server
is inside my router cupboard though, so I'll treat this as merely a bit
of extra security.

Hi chill

I have an Argon one case (no fan), if these are your defaults, I don't
think your fan will ever turn on. :D

This works perfectly.  The argononed.conf file can now be edited while
the script is running, and the changes are applied on the fly.  In fact
I moved the whole fanconfig block inside the loop, so that the script
will continue to operate with the defaults even if the conf file is
deleted.


Code:

def temp_check():
  # fanconfig = ["65=100", "60=55", "57=30", "55=10", "30=0"]
  # tmpconfig = load_config("etc/argononed.conf")
  # tmpconfig = load_config("/home/tc/argononed.conf")
  # if len(tmpconfig) > 0:
  # fanconfig = tmpconfig
address=0x1a
prevblock=0
while True:
fanconfig = ["65=100", "60=55", "57=30", "55=10", "30=0"]
tmpconfig = load_config("/home/tc/argononed.conf")
if len(tmpconfig) > 0:
fanconfig = tmpconfig
temp = os.popen("vcgencmd measure_temp").readline()
temp = temp.replace("temp=","")
val = float(temp.replace("'C",""))
block = get_fanspeed(val, fanconfig)
if block < prevblock:
time.sleep(30)
prevblock = block
try:
bus.write_byte(address,block)
except IOError:
temp=""
time.sleep(30)



This is useful for testing purposes - I changed the conf file to contain
a single entry, '35=100', and within 30 seconds the fan came on at 100%.
I renamed the conf file, and within 30 seconds the fan turned off again
in accordance with the defaults in the python script.

Excellent - thanks Paul, that's a really useful post.  I've received
word that my M2 SSD and the Argon One adapter/tray will arrive today, so
I'm looking forward to having a play.  In the meantime I'm going to try
this out on my existing SATA SSD.

Re: [SlimDevices: Unix] [How To] Using the Argon One case for the Pi 4B together with piCorePlayer (7.x)

sg3_utils.tcz is uploaded to the repo.
busybox does have lsusb command, but its limited in output. You can get
the USB identifiers from dmesg.or you can download the full bloated
usbutils.tcz extension.
I did not build lsscsi, as more than likely you only have one device
listed, and that info is not even needed for the udev rule.

Neither of these you will need long term, so you can just download them,
and load them when you want.

For those that didn't know
"tce-load -wi sg3_utils.tcz" - Will download, install and put this in
your onboot.lst, so it is automatically loaded every time
"tce-load -w sg3_utils.tcz" - Will just download the extension and
dependanciesnot do anything more
"tce-load -i sg3_utils.tcz" - Will install a previously downloaded
extension, but does not add to onboot.lst.

I would recommend this process.
1 - Figure out your settings from the instructions.
2 - Create the udev rule anywhere on your system.
3 - In the file /opt/bootlocal.sh (Before pCP starts), copy the rule
from where ever you saved it to /etc/udev/rules.d
4 - Reload the udev rules and trigger udev.
5 - Create a script to run after pCP starts to run the initial fstrim
operation, since the unmap data is only maintained in the kernel.
6 - Run your periodic fstrim via a cron script.

Here is my bootlocal

Code:

cp /opt/80-samsung-t5.rules /etc/udev/rules.d/
udevadm control --reload-rules
udevadm trigger

Code:

fstrim -v /mnt/mountpoint > /var/log/pcp_trim.log

When I look at the code, block is simply the percent value for the fan
of the matching fan entry:

Code:

fancfg = int(float(curpair[1]))



curpair[1] is what is behind the "=" and int(float(...)) will simply
make an int of this value. If someone used eg. "10.3" it will result in
a "10".


Code:

but if fanconfig changes then I think the link between block and prevblock 
will be broken.



Yes, that has to happen! Even if the temperature changes, block will
change if it's in a new range.
The value of block will be given to the hardware of the Argon case in
the line:

Code:

bus.write_byte(address,block)

I'm not so sure - I don't know what 'block' looks like (coming back from
'get_fanspeed'), but if fanconfig changes then I think the link between
block and prevblock will be broken.  Probably not important for one
iteration of the loop, but I'd want to look more closely at what
happens.

As for the performance penalty for reading the file every 30 seconds, I
think it will be negligible.  I have a similar shell script (to turn my
own fan on and off via GPIO).  That reads an external file quite happily
every 5 seconds with no apparent ill-effects!

Mine is telling me this:

The USB stick in the other USB 3 port is telling me the same.

Sure, but what I haven't grasped yet is whether 'enabling' it for a
specific drive is something that is done in the drive's firmware (so it
would show as 'enabled' under any trim-capable OS), or whether it just
configures the current OS to enable it for that drive.  I suspect the
former, but I need to read that blog more carefully.

Thank you very much. I changed the description accordingly.

I also don't know python, but I would make it the following way:

Code:

while True:
temp = os.popen("vcgencmd measure_temp").readline()
temp = temp.replace("temp=","")
val = float(temp.replace("'C",""))
fanconfig = load_config("/home/tc/argononed.conf")

But I don't know what happens to the performance then, because every 30

You can try it. :-)

Thank you.  My existing SATA SSD, connected to USB3 via a SATA-to-USB
adapter, gives the response below to fstrim.  It's the same response
that my USB3 flash drive gives.  It's a different response to the one
suggested in that blog post ('fstrim: /: the discard operation is not
supported'), but I guess the interpretation is the same - trim isn't
enabled.

Code:

sudo fstrim -v /mnt/Music
  fstrim: FITRIM: Operation not supported

If you have tools to a) determine whether trim is supported in firmware
and b) enable it if so, then they could be useful, but don't rush - I'll
see what I get with the new M.2 SATA drive when it arrives.

fstrim is supported.   I have the other tools, I just never packaged

Re: [SlimDevices: Unix] [How To] Using the Argon One case for the Pi 4B together with piCorePlayer (7.x)



Trim support rarely documented in the controller documentation.  But in
general, USB controllers do not support the online trim.   Some do
support kernel 'unmap'  (The kernel keeps track of what needs trimmed)

Here is a quick article I found, which at least describes what's going
on.
https://lemariva.com/blog/2020/08/raspberry-pi-4-ssd-booting-enabled-trim
There were not as nice of writeups availiable when I set this up on my
Samsumg T5 SSD.  

Please note the warnings in the blog.

Re: [SlimDevices: Unix] [How To] Using the Argon One case for the Pi 4B together with piCorePlayer (7.x)



I've tweaked the python script to make it slightly easier to use a
separate config file under pCP.  I changed the 'tmpconfig' line as
folows:


Code:

#   tmpconfig = load_config("etc/argononed.conf")
tmpconfig = load_config("/home/tc/argononed.conf")
  



Then I put this argononed.conf example file in /home/tc


Code:

#
  # Argon One Fan Configuration
  #
  # List below the temperature (Celsius) and fan speed (in percent) pairs
  # Use the following form:
  # min.temperature=speed
  #
  # Example:
  # 55=10
  # 60=55
  # 65=100
  #
  # NOTE: Lines beginning with # are ignored
  #
  # Start below:
  55=10
  60=55
  65=100



To make any changes in this file take effect the python script needs to
be restarted, e.g. by (backing up and) rebooting (or the process can be
killed and then restarted from the command line).  This means there's
very little benefit compared to editing the python script itself.  But
at least with this method the python script can be left untouched.

If I knew anything about python I'd have a go at making it re-load this
'argononed.conf' file every time it checks the temperature, so that it
can be changed on-the-fly without restarting the script.  But I think a
few default temperature settings are good enough that I can put off
learning python for a bit longer :-)

That is clear, also it is only a M.2 SATA SSD not an M.2 NVMe SSD, so it
will not be faster as an external attached USB 3 SATA SSD.

Just so you are aware, although pretty fast the, full speed of the M.2,

Also I saw a list with adapters that work together with the Pi 4 and it
is on this list.
Here is the list (German forum, it is the one with the link to

According to 'here'
(https://thepihut.com/products/argon-one-m-2-raspberry-pi-4-case), the
Argon M.2-to-USB adapter supports UASP.  What can I use under pCP7 to
check/test trim support?

Looks like Argon is supplying the M.2 to USB3 converter.  I hope they
did their homework, as there are some adapters that don't work well with
the PI4.

Not sure how well these adapters are supported with trim support either.

It seems that the only connection between the M.2 SSD tray and the RPi
is that little rigid USB link piece that connects to the RPi's lower
USB3 socket.

So if you wanted to go down that route, I would imagine that you could
shut down the RPi, remove that junction piece, and connect the tray to
your Mac with a 'USB3 male-to-male cable'
(https://www.lindy.co.uk/cables-adapters-c1/usb-c449/2m-flat-usb-3-0-cable-type-a-male-to-a-male-black-p6683)
instead.

I also thought about it. But I attach the SSD with my music data often
to my Mac to synchronise it with the music stored there (the SSD is in
HFS+ format and a 1:1 copy of my iTunes/Music library and it is mounted
ro on the Pi). So the integrated SSD will be a little bit complicated to
attach it to the Mac and the Pi.
For PCP I am using the SD card and I have an extra USB Stick for the LMS
library in one USB 3 port.

Oh, I didn't know that this exists. The difference to the V1 are the
full size HDMI connectors instead of the micro HDMI and that there is an
infrared receiver installed (you can install it on your own on the V1
boards).

I've just ordered that M.2 SSD add-on tray and a suitable SSD.  I think
it's worth it to make a neat all-in-one server that will occupy a
minimum of space in my router cupboard.  It'll just have power and an
ethernet cable connected to the back, and a USB3 flash drive for
booting, including a separate partition for the LMS cache and boot/root
backups.

No, the V2 does not have the SSD space below ('although I note that it
can be added'
(https://thepihut.com/products/m-2-expansion-board-for-argon-one)). 
It's this one:
https://thepihut.com/collections/raspberry-pi-cases/products/argon-one-raspberry-pi-4-case
I have no idea if there was a V1, or how it differs - it's simply the
one currently offered by Pi Hut!

Many thanks for your reply to it!

It is really great! You wrote V2, so you have the one with the M.2 SSD
at the bottom?
There is also another one for Audio tasks:

Oh, I didn't know that, but it explains why they worked on my old

I will change the text!
