Fixed In Version: ceph-17.2.6-125.el9cp
Doc Type: Bug Fix
Doc Text:
.Errors are handled gracefully in `MDLog::_recovery_thread` Previously, a write would fail if the MDS was already blocklisted due to the `fs fail` issued by the QA tests. For instance, the QA test `test_rebuild_moved_file` (tasks/data-scan) would fail due to this reason. With this fix, the write failures are gracefully handled in `MDLog::_recovery_thread`.
