Support #17271
Updated by Nico César about 4 years ago
If you have the following versions
linux kernel > 4.x
systemd > 247 (en debian family)
docker > 20.10
Is very likely that you have cgroupsv2 enable by default. You can check by doing
<pre>
if [ -e /sys/fs/cgroup/cgroup.controllers ]
then
echo "cgroupsV2 enabled"
fi
</pre>
Unfortunately Arvados 2.1 doesn't have support for cgrupsV2 so compute nodes need to have this disabled
this can be done by adding `systemd.unified_cgroup_hierarchy=0` to the kernel parameters.
Debian / Ubuntu:
in /etc/default/grub make sure that you have
GRUB_CMDLINE_LINUX="systemd.unified_cgroup_hierarchy=0"
<pre>
update-grub
</pre>
Fedora 31
<pre>
dnf install -y grubby
grubby --update-kernel=ALL --args=”systemd.unified_cgroup_hierarchy=0"
</pre>
