Description Mudit Agarwal 2023-03-27 04:44:07 UTC 
+++ This bug was initially created as a clone of Bug #2175307 +++

Description of problem:

This RFE is for a functionality in the MDS to detect specific damage to the metadata "dentries". The damage is associated with a long-standing bug (#38452).

This change will catch the damage before it's persisted. If **new** damage is detected to be written to persistent storage (i.e. RADOS), the MDS will abort to avoid persisting damage. This will hopefully have the benefit of providing logs in the same time period that the damage was created for analysis.

https://tracker.ceph.com/issues/58482

Documentation for support when customers encounter the abort will be forthcoming and available before 6.1 is released.
Comment 4 krishnaram Karthick 2023-04-07 06:03:44 UTC 
This is a ceph RFE and the change will be in 4.13 as part of RHCS 6.1. 
From ODF, I don't see any feature is dependent on the ceph RFE, so we will verify the bug based on regression.
Comment 11 Elad 2023-06-06 08:22:47 UTC 
Moving to VERIFIED based on regression testing using ODF 4.13.0 builds starting 4.13.0-184
