Title:
cephadm does not work with zfs root
I think the reason that ZFS behaves differently is because of this...
/usr/lib/python3.6/site-packages/ceph_volume/devices/raw/activate.py
from ceph_volume.util import system
# mount on tmpfs the osd directory
osd_path = '/var/lib/ceph/osd/%s-%s' % (conf.cluster, osd_id)
if not
Follow up - it does seem to be the tmpfs mount that activate creates
that causes the problem.
I manually started the activate container by running the podman command
from unit.run for the activate step, but just ran "bash -l" instead of
the actual activate command
Then I prevented the mount
For what it's worth, I've now had the exact same problem, which led me
here.
On a bare-metal 20.04 using full blank HDDs as OSDs (/dev/sda etc.),
installing using cephadm worked fine with an XFS root, but later on when
I reinstalled and tried ZFS root, I then got the same behaviour
described
We tried docker by itself then tried ceph ansible by itself to deploy.

for ceph ansible we used version 5

BTW, how did you install ceph-ansible? I can't find a 20.04 package in
the ansible ppa.

Title:
cephadm does not work with zfs
I was pretty much following this simple tutorial:
http://prashplus.blogspot.com/2018/01/ceph-single-node-setup-ubuntu.html
I'll try to add docker and ceph-ansible to the equation and see if I can
reproduce it.

We are using the latest Ubuntu 20.04 and we ahve tried ceph ansible +
docker deploy and both of those give us issues with zfs root fs. How are
you deploying?
If you give me your list of commands + image I can retry.

I've tried to reproduce the problem on a VM (that uses ZFS as rootfs)
setting up a single-node ceph cluster, but OSD is coming up correctly:
$ sudo ceph -s | grep osd
osd: 1 osds: 1 up (since 50m), 1 in (since 59m)
Could you provide more details about your particular ceph configuration
