[ceph-users] Re: non root deploy ceph 17.2.5 failed

[Eugen Block]

Hi,

I just retried without the single-host option and it worked. Also  
everything under /tmp/var belongs to root in my case. Unfortunately, I  
can't use the curl-based cephadm but the contents are identical, I  
compared. Not sure what it could be at the moment.

Hi, It is uos v20(with kernel 4.19), one linux distribution among others.
no matter since cephadm deploys things in containers by default. cephadm is
pulled by curl from Quincy branch of github.

I think you could see some sort of errors if you remove parameter
--single-host-defaults.

More investigation shows it looks like a bug with cephadm.
during the deploying procedure
,/tmp/var/lib/ceph/ad3a132e-e9ee-11ed-8a19-043f72fb8bf9/cephadm.059bfc99f5cf36ed881f2494b104711faf4cbf5fc86a9594423cc105cafd9b4e.new
is created through sudo ssh session remotely(with owner of root) and
/tmp/var/lib/ceph/ad3a132e-e9ee-11ed-8a19-043f72fb8bf9/ is changed to owner
of ssh user deployer. The correct thing to do instead is,  /tmp/var/ be
changed to the owner deployer recursively so that following scp can have
access permission.
I will see if having time to wire up a PR to fix it.

Thanks for help on this.
Ben

Hi,

could you provide some more details about your host OS? Which cephadm
version is it? I was able to bootstrap a one-node cluster with both
17.2.5 and 17.2.6 with a non-root user with no such error on openSUSE
Leap 15.4:
