Hello Cephers,
I am unable to create the initial monitor during ceph cluster deployment. I do
not know what changed since the same recipe used to work until very recently.
These are the steps I used:
Ceph-deploy new <hostname> -- works
Dpkg -i -R <path to built deb packages> --works
Ceph-deploy mon create-initial - fails
Log:

[Myhost][WARNING] monitor: mon.myhost, might not be running yet
I checked the monitor log in /var/log/ceph and it does not have anything
unusual, just the pid for the ceph-mon process. However, there is no
/var/run/ceph/ceph-mon.myhost.asok. I do not know in which step this file is
created; hence I am not able to debug this issue. Any pointers wrt this issue
would be appreciated. I am using the BLKIN Ceph branch (wip-blkin) i.e. 9.0.1
Ceph packages built from source and my ceph-deploy version is 1.5.28.
Thanks,
Aakanksha
