Has anyone built a ClusterCTRL image from scratch on any RedHat-ish release?

[Tony Brack]

Greetings All,

Yes: I know this all works on Debian flavors.

Before I go down a rat hole I may not need to, has anybody successfully installed clusterctrl on any RedHat flavor of Linux, and if so, how did you acomplish it? Is it a lost cause to start with? Are there some other repositories I should know about? Just wondering if anyone has experience doing this ...

I tried briefly to do this on almalinux and got the following behavior:

[bracka@almalinux ~]$ hostnamectl

        Machine ID: 5b54ae6140e745bbbe703795bffff63b

The python2 results are similar. I have not yet tried Fedora.

Thanks in Advance,

Hi,

 On AlmaLinux this will get the clusterctrl command running but I haven't been able to get the udev rules working yet.

TMPINSTALL=/tmp/clusterhat
dnf config-manager --add-repo https://repo.almalinux.org/almalinux/8/devel/almalinux-devel.repo

dnf --enablerepo=devel install python3-i2c-tools
dnf install git python3-pyusb python3 usbutils i2c-tools

git clone https://github.com/burtyb/clusterhat-image.git $TMPINSTALL

mkdir /usr/share/clusterctrl/

cp $TMPINSTALL/files/usr/sbin/cluster* /usr/sbin/
cp $TMPINSTALL/files/usr/share/clusterctrl/default-clusterctrl /etc/default/clusterctrl
cp $TMPINSTALL/files/etc/udev/rules.d/90-clusterctrl.rules /etc/udev/rules.d/
cp $TMPINSTALL/files/usr/lib/systemd/system/clusterctrl-init.service /usr/lib/systemd/system/
cp -r $TMPINSTALL/files/usr/share/clusterctrl/python/ /usr/share/clusterctrl/
echo 'TYPE=c' >> /etc/default/clusterctrl

systemctl enable clusterctrl-init
echo -e "\ndtparam=i2c1=on\n" >> /boot/config.txt
rm -rf $TMPINSTALL
reboot

Hi Chris,

It's working well so far and I'm still figuring things out. I am going to follow up with some of the stuff you are working on, but having said this, I did encounter a very minor shortcoming. I am testing/developing with a v2.4 hat and no fan, so not a big deal.

[bracka@coruscant clusterhat]$ sudo clusterctrl status
clusterhat:1
clusterctrl:False
maxpi:4
throttled:NA
hat_version:2.4
hat_version_major:2
hat_version_minor:4
hat_size:4
hat_uuid:de91a4ce-ac7f-11e9-a2a3-2a2ae2dbcce4
hat_vendor:8086 Consultancy
hat_product_id:0x0004
hat_alert:0
hat_hub:1
hat_wp:1
hat_led:1
hat_wplink:0
hat_xra1200p:True
p1:1
p2:0
p3:0

p4:0

[bracka@coruscant clusterhat]$ sudo clusterctrl fan on

Traceback (most recent call last):
  File "/sbin/clusterctrl", line 982, in <module>
    import RPi.GPIO as GPIO

Almalinux has its own unrelated issues ...

Hi, 

[bracka@coruscant clusterhat]$ sudo clusterctrl fan on

Traceback (most recent call last):

You can turn off fan support by commenting out the FANGPIO line in /etc/defaults/clusterctrl

Or you can install  RPi.GPIO that it's trying to use (for fan control and v1.x ClusterHAT) with something like this.

sudo yum install gcc python36-devel

pip3 install RPi.GPIO
