Fixed In Version: ceph-18.2.1-295.el9cp
Doc Type: Bug Fix
Doc Text:
MDS can now handle duplicate links to a directory Previously, cephfs-data-scan during disaster recovery did not create a missing directory fragment from backtraces or create duplicate links in some situations. As a result, the directories became inaccessible or crashed the MDS. With this fix, cephfs-data-scan properly recreates missing directory fragments and corrects duplicate links. Recovery is now easy, and the MDS can better handle duplicate links to a directory.
