Folding Forum

I have 9 headless RPi machines each configured with 4 CPUs assigned.
Only 6 show on the tampabay_tech client machine list.
None show in the Tampabay (#1066617) team list.
All are Ethernet connected to the same router.
Software is Bookworm and fah-client_8.4.9_arm64.deb
The /etc/fah-client/config.xml file has not been edited.

The status is:
CS0 - RPi 5b w/4GB mem - connected & folding & machine is listed
CS1 - RPi 4b w/4GB mem - connected & folding & machine is listed
CS2 - RPi 4b w/4GB mem - connected & no work & machine is listed, "HTTP_SERVICE_UNAVAILABLE: {"error":"No appropriate assignment"}, DNS lookup failed for assign1.foldingathome.org
CS3 - RPi 4b w/1GB mem - fah-client active, running & machine is not list
CS4 - RPi 4b w/4GB mem - fah-client active, running & machine is not list
CS5 - RPi 4b w/1GB mem - fah-client active, running & machine is not list
CS6 - RPi 4b w/4GB mem - connected & folding & machine is listed
CS7 - RPi 4b w/4GB mem - connected & folding & machine is listed
CS8 - RPI 5b w/8GB mem - connected & folding & machine is listed

I've tried rebooting, reinstalling the OS and fah-client without success.
I've not found any documentation that addresses these issues.
This is my first exposure to Linux and F@H. I'm a complete novice.
I'm looking for guidance.

Maybe add account-token to config.xml?

No joy. Each config.xml file contains:
<config>
<account-token v="soc6FsocM29qxM296ZdoF6Zd9abIq9aa97s5g972x2I"/>
</config>

CS0 boots and is folding. CS1 through CS8 fail to start fah-client.service. The logs did not contain anything useful.

If they stopped launching after you edited config.xml, then you probably have an xml error.

You might want to remove
StandardOutput=null
from the service file.
Temporarily, of course.

sudo systemctl edit fah-client

The service file was empty except for the comment lines. I tried adding StandardOutput=null.
The results were the same so I removed it. The machine list includes CS0 folding; CS1, CS2, CS6, CS7, CS8 are disconnected; CS3, CS4, CS5 are not listed.
The config.xml file contains
<config>
<account-token v="soc6FsocM29qxM296ZdoF6Zd9abIq9aa97s5g972x2I"/>
</config>

CS1 - CS8 failed loading fah-client.service. The logs did not have any applicable entries.

This is a lot of struggle for the machines, which either never or very very rarely receive any work.
Majority of them are too slow to fold, others will still be disabled because of the constraints enveloping all the ARM on Linux, with 4 cores or less

I would surmise that a RPi 5 would have sufficient computing power. Why would a RPi software version be offered if the CPU couldn't handle the load?

Software is not specifically for RPi. It is for ARM on Linux. ARM has some exotic stuff which is very capable, yet very not available to common people.
Looking at the list of yours, 80% of your devices are RPi 4s, which are too slow 95% of the time

Thanks for the info. I'll find a different project.
