Hi Alfredo Deza I see your below PR in ceph PR 23289 "ceph-volume ensure encoded bytes are always used" I meet with one problem when using ceph-deploy to deploy ceph cluster. During running ceph-volume command to create OSD through ceph-deploy, it always hit below problem: nstcc1@nstcloudcc1:deploy$ PYTHONIOENCODING=UTF8 ceph-deploy osd create --data /dev/sdc nstcloudcc1 [nstcloudcc1][WARNIN] stderr: purged osd.0 [nstcloudcc1][WARNIN] --> UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 132: ordinal not in range(128) [nstcloudcc1][ERROR ] RuntimeError: command returned non-zero exit status: 1 [ceph_deploy.osd][ERROR ] Failed to execute command: /usr/sbin/ceph-volume --cluster ceph lvm create --bluestore --data /dev/sdc [ceph_deploy][ERROR ] GenericError: Failed to create 1 OSDs Do you know how to solve the problem?
