v14.2.10 Nautilus released

This is the tenth release in the Nautilus series. In addition to fixing a security-related bug in RGW, this release brings a number of bugfixes across all major components of Ceph. We recommend that all Nautilus users upgrade to this release.

Notable Changes

  • CVE-2020-10753: rgw: sanitize newlines in s3 CORSConfiguration’s ExposeHeader (William Bowling, Adam Mohammed, Casey Bodley)

  • RGW: Bucket notifications now support Kafka endpoints. This requires librdkafka of version 0.9.2 and up. Note that Ubuntu 16.04.6 LTS (Xenial Xerus) has an older version of librdkafka, and would require an update to the library.

  • The pool parameter target_size_ratio, used by the pg autoscaler, has changed meaning. It is now normalized across pools, rather than specifying an absolute ratio. For details, see Autoscaling placement groups. If you have set target size ratios on any pools, you may want to set these pools to autoscale warn mode to avoid data movement during the upgrade:

    ceph osd pool set <pool-name> pg_autoscale_mode warn
    
  • The behaviour of the -o argument to the rados tool has been reverted to its orignal behaviour of indicating an output file. This reverts it to a more consistent behaviour when compared to other tools. Specifying object size is now accomplished by using an upper case O -O.

  • The format of MDSs in ceph fs dump has changed.

  • Ceph will issue a health warning if a RADOS pool’s size is set to 1 or in other words the pool is configured with no redundancy. This can be fixed by setting the pool size to the minimum recommended value with:

    ceph osd pool set <pool-name> size <num-replicas>
    

    The warning can be silenced with:

    ceph config set global mon_warn_on_pool_no_redundancy false
    
  • RGW: bucket listing performance on sharded bucket indexes has been notably improved by heuristically – and significantly, in many cases – reducing the number of entries requested from each bucket index shard.
