[ceph-users] ceph plugin balancer error
Hi, I am running test on ceph mimic 13.0.2.1874+ge31585919b-lp150.1.2 using openSUSE-Leap-15.0 when I ran "ceph balancer status", it errors out. g1:/var/log/ceph # ceph balancer status Error EIO: Module 'balancer' has experienced an error and cannot handle commands: 'dict' object has no attribute 'iteritems' what config need to be done in order to get it work?

weird thing is that, g1:~ # locate /bin/python /usr/bin/python /usr/bin/python2 /usr/bin/python2.7 /usr/bin/python3 /usr/bin/python3.6 /usr/bin/python3.6m g1:~ # ls /usr/bin/python* -al lrwxrwxrwx 1 root root 9 May 13 07:41 /usr/bin/python -> python2.7 lrwxrwxrwx 1 root root 9 May 13 07:41 /usr/bin/python2 -> python2.7 -rwxr-xr-x 1 root root 6304 May 13 07:41 /usr/bin/python2.7 lrwxrwxrwx 1 root root 9 May 13 08:39 /usr/bin/python3 -> python3.6 -rwxr-xr-x 2 root root 10456 May 13 08:39 /usr/bin/python3.6 -rwxr-xr-x 2 root root 10456 May 13 08:39 /usr/bin/python3.6m my default python env is 2.7... so under dict object should have iteritems method Chris ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

I have tried to modify /usr/lib64/ceph/mgr/balancer/module.py replace iteritems () with items(), but I still got following error g1:/usr/lib64/ceph/mgr/balancer # ceph balancer status Error EINVAL: Traceback (most recent call last): File "/usr/lib64/ceph/mgr/balancer/module.py", line 297, in handle_command return (0, json.dumps(s, indent=4), '') File "/usr/lib64/python3.6/json/__init__.py", line 238, in dumps **kw).encode(obj) File "/usr/lib64/python3.6/json/encoder.py", line 201, in encode chunks = list(chunks) File "/usr/lib64/python3.6/json/encoder.py", line 430, in _iterencode yield from _iterencode_dict(o, _current_indent_level) File "/usr/lib64/python3.6/json/encoder.py", line 404, in _iterencode_dict yield from chunks File "/usr/lib64/python3.6/json/encoder.py", line 437, in _iterencode o = _default(o) File "/usr/lib64/python3.6/json/encoder.py", line 180, in default o.__class__.__name__) TypeError: Object of type 'dict_keys' is not JSON serializable it seems to me that ceph mgr is complie/written for python 3.6 but balancer plugin is written for python 2.7... this might be related https://github.com/ceph/ceph/pull/21446 this might be opensuse building ceph package issue chris ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

Hi Chris: I suggest you raise your openSUSE Ceph-related questions on the openSUSE Ceph mailing list instead of ceph-users. For info on how to join, go to https://en.opensuse.org/openSUSE:Ceph#Communication The version of Ceph currently shipping in Leap 15.0 is built against Python 3 and this, as you found, exposes python2-specific code in the Ceph codebase. We might reconsider this and push a Python 2 build to Leap 15.0 - let's discuss it on opensuse-ceph.

Re: [ceph-users] ceph plugin balancer error
Update: opened http://tracker.ceph.com/issues/24779 to track this bug, and am in the process of fixing it. The fix will make its way into a future mimic point release. Thanks, Chris, for bringing the issue to my attention!
