Description
One of our CephFS volumes has become corrupt, with user files being substituted for each other with no clear pattern; eg User A's ~/.ssh/id_rsa, when read, may return the contents of another user's id_rsa; User B's id_rsa may return a different user's ~/.profile, etc. The returned data sometimes includes the contents of multiple files, and is interspersed with null bytes in some cases, which leads me to believe Ceph is retrieving the wrong raw data blocks rather than simply swapping file handles. This is of course causing a major security incident.
Please let me know what debug data would be useful. Thanks.
