Hello Josh Thank you your for reply to us. After giving the command in the cluster I got the following error. We are concerned about user data. Could you kindly confirm this command will not affect any user data? root@ceph-node1:/# ceph osd rm-pg-upmap-primary Traceback (most recent call last): File "/usr/bin/ceph", line 1327, in <module> retval = main() File "/usr/bin/ceph", line 1036, in main retargs = run_in_thread(cluster_handle.conf_parse_argv, childargs) File "/usr/lib/python3.6/site-packages/ceph_argparse.py", line 1538, in run_in_thread raise t.exception File "/usr/lib/python3.6/site-packages/ceph_argparse.py", line 1504, in run self.retval = self.func(*self.args, **self.kwargs) File "rados.pyx", line 551, in rados.Rados.conf_parse_argv File "rados.pyx", line 314, in rados.cstr_list File "rados.pyx", line 308, in rados.cstr UnicodeEncodeError: 'utf-8' codec can't encode characters in position 3-4: surrogates Apart from that, do you need any others information?
