There is a bug in v13.2.2 mds, which causes decoding purge queue to fail. If mds is already in damaged state, please downgrade mds to 13.2.1, then run 'ceph mds repaired fs_name:damaged_rank' .

Sorry for all the trouble I caused. Yan, Zheng

This issue is being tracked here: http://tracker.ceph.com/issues/36346 The problem was caused by a backport of the wrong commit which unfortunately was not caught. The backport was not done to Luminous; only Mimic 13.2.2 is affected. New deployments on 13.2.2 are also affected but do not require immediate action. A procedure for handling upgrades of fresh deployments from 13.2.2 to 13.2.3 will be included in the release notes for 13.2.3. -- Patrick Donnelly
