Just FYI, 14.2.8 build fails on Fedora-32 on S390x. Other architectures build fine.
Kaleb, see https://github.com/ceph/ceph/pull/33716. hopefully we can get in the next release or probably you could include this patch in the rpm packaging?

This is the eighth update to the Ceph Nautilus release series. This release fixes issues across a range of subsystems. We recommend that all users upgrade to this release. Please note the following important changes in this release; as always the full changelog is posted at: https://ceph.io/releases/v14-2-8-nautilus-released
Notable Changes ---------------
* The default value of `bluestore_min_alloc_size_ssd` has been changed to 4K to improve performance across all workloads.
* The following OSD memory config options related to bluestore cache autotuning can now be configured during runtime:
- osd_memory_base (default: 768 MB) - osd_memory_cache_min (default: 128 MB) - osd_memory_expected_fragmentation (default: 0.15) - osd_memory_target (default: 4 GB)
The above options can be set with::
ceph config set osd <option> <value>
* The MGR now accepts `profile rbd` and `profile rbd-read-only` user caps. These caps can be used to provide users access to MGR-based RBD functionality such as `rbd perf image iostat` an `rbd perf image iotop`.
* The configuration value `osd_calc_pg_upmaps_max_stddev` used for upmap balancing has been removed. Instead use the mgr balancer config `upmap_max_deviation` which now is an integer number of PGs of deviation from the target PGs per OSD. This can be set with a command like `ceph config set mgr mgr/balancer/upmap_max_deviation 2`. The default `upmap_max_deviation` is 1. There are situations where crush rules would not allow a pool to ever have completely balanced PGs. For example, if crush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of the racks. In those cases, the configuration value can be increased.
* RGW: a mismatch between the bucket notification documentation and the actual message format was fixed. This means that any endpoints receiving bucket notification, will now receive the same notifications inside a JSON array named 'Records'. Note that this does not affect pulling bucket notification from a subscription in a 'pubsub' zone, as these are already wrapped inside that array.
* CephFS: multiple active MDS forward scrub is now rejected. Scrub currently only is permitted on a file system with a single rank. Reduce the ranks to one via `ceph fs set <fs_name> max_mds 1`.
* Ceph now refuses to create a file system with a default EC data pool. For further explanation, see: https://docs.ceph.com/docs/nautilus/cephfs/createfs/#creating-pools
* Ceph will now issue a health warning if a RADOS pool has a `pg_num` value that is not a power of two. This can be fixed by adjusting the pool to a nearby power of two::
ceph osd pool set <pool-name> pg_num <new-pg-num>
Alternatively, the warning can be silenced with::
ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
