distro testing for reef * https://github.com/ceph/ceph/pull/49443 adds centos9 and ubuntu22 to supported distros * centos9 blocked by teuthology bug https://tracker.ceph.com/issues/58491 - lsb_release command no longer exists, use /etc/os-release instead - ceph stopped depending on lsb_release in 2021 with https://github.com/ceph/ceph/pull/42770 * ubuntu22 not blocked by teuthology, but the new python version breaks most of the rgw tests
can we drop centos8 or ubuntu20 support for reef? * we usually support the latest centos and two ubuntu LTSs * users need an upgrade path that doesn't require OS and ceph upgrade at the same time * we might be able to drop centos8 support for Reef by adding centos9 support to Quincy * python versioning issues make longer-term support of older distros problematic. related work: - https://github.com/ceph/ceph/pull/41979 - https://github.com/ceph/ceph/pull/47501 ondisk format changes in minor releases * https://github.com/ceph/ceph/pull/48915 introduced some BlueFS log changes in 16.2.11 which makes it incompatible with previous Pacific releases. Hence no downgrade is permitted any more. - doc text tracked in https://tracker.ceph.com/issues/58625 * how do we prevent these issues in the future? - better testing of mixed-version rgw/mds/mgr/etc infrastructure update * a planned network outage yesterday still affecting LRC _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
