Hello
My upgrade from 15.2.12 to 16.2.4 is stuck because a mon
daemon failed to upgrade. Systemctl status of the mon showed
this error:
Error: open /sys/fs/cgroup/cpuacct,cpu/system.slice/...
It turns out there is no /sys/fs/cgroup/cpuacct,cpu
directory on my system. Instead, I have
/sys/fs/cgroup/cpu,cpuacct. Symlinking them appears to have
solved the immediate problem, but if I proceed with the
upgrade to 16.2.4, after reboot, all ceph daemons will
probably fail to start.
Is this an issue with ceph, podman (2.1.1), or the fact that
I am running Centos7?
Is it possible to upgrade from 15.2.12 to 16.2.4 on Centos7?
I thought that installing a version of podman that is
compatible with both would suffice, but apparently not...
Vlad
