ceph
I can ssh successfully my ceph osd nodes but when i am trying to copy ssh id i am getting below error can anyone guide why i am getting below errors.
[ceph@monitor ~]$ ssh-copy-id ceph@osd-0
/bin/ssh-copy-id: ERROR: failed to open ID file '/home/ceph/.pub': No such file or directory
(to install the contents of '/home/ceph/.pub' anyway, look at the -f option)
[ceph@monitor ~]$
I did eventually work out what was wrong. I had to manually change 'type host' to 'type osd' in our crushmap, which is different from Spongman's suggestion.
after booting rgw, I find that the owner of radosgw process is "root", not "ceph". command "ceph -s" also show that "100.000% pgs not active".
I search the clue "100.000% pgs not active", the post "https://www.cnblogs.com/boshen-hzb/p/13305560.html" tell how to solve it - change 'type host' to 'type osd' , as result, "ceph -s" show "HEALTH_OK" and the owner of radosgw process become "ceph", and rgw web service(7480) is listening.
The conversion from volume to image happens on the local disk of the controller. Check df -h while the conversion is running, your /var filesystem could be filling up if you haven't enough disk space. Check the directory /var/lib/cinder/conversion, this is where the volume is temporarily stored before uploading it back to ceph as an image. It's a good idea to have an own logical volume (if you use LVM) for /var/lib/cinder/conversion to prevent the filesystem from filling up. If you don't have enough local disk space you could just mount a shared filesystem (e.g. cephFS, NFS, etc.) to /var/lib/cinder/conversion.

your local public key is not found in
/home/ceph/.pubBy default, your SSH keys are in
/home/user/.ssh/key[.pub]You can specify the right key to use with the
-i(i for 'identity') option :ssh-copy-id user@server -i /file/to/use
