Thanks a lot for your help, Varada. Since I was deploying Ceph via ceph-deploy I could not see the actual errors. Low disk space led to a failure in creating monfs. Things are now working fine. Thanks, Aakanksha From: Varada Kari [mailto:Varada.Kari@xxxxxxxxxxx]
Could you try starting the monitor manually and see what the error is? Like ceph-mon –i <id> --cluster ceph &. Enable more logging (debug_mon).

On Behalf Of Aakanksha Pudipeddi-SSI I am still unable to get past this issue. Could anyone help me out here? Thanks, Aakanksha From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of Aakanksha Pudipeddi-SSI 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: [ceph_deploy.cli][INFO ] Invoked (1.5.28): /usr/bin/ceph-deploy mon create-initial [ceph_deploy.cli][INFO ] ceph-deploy options: [ceph_deploy.cli][INFO ] username : None [ceph_deploy.cli][INFO ] verbose : False [ceph_deploy.cli][INFO ] overwrite_conf : False [ceph_deploy.cli][INFO ] subcommand : create-initial [ceph_deploy.cli][INFO ] quiet : False [ceph_deploy.cli][INFO ] cd_conf : <ceph_deploy.conf.cephdeploy.Conf instance at 0x7fee2e80b7a0> [ceph_deploy.cli][INFO ] cluster : ceph [ceph_deploy.cli][INFO ] func : <function mon at 0x7fee2e7e5aa0> [ceph_deploy.cli][INFO ] ceph_conf : None [ceph_deploy.cli][INFO ] default_release : False [ceph_deploy.cli][INFO ] keyrings : None [ceph_deploy.mon][DEBUG ] Deploying mon, cluster ceph hosts myhost [ceph_deploy.mon][DEBUG ] detecting platform for host myhost ...

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 |
