Description
It was introduced by https://tracker.ceph.com/issues/54049.
From the options:
462 - name: client_die_on_failed_dentry_invalidate 463 type: bool 464 level: advanced 465 desc: kill the client when no dentry invalidation options are available 466 long_desc: The CephFS client requires a mechanism to invalidate dentries in the 467 caller (e.g. the kernel for ceph-fuse) when capabilities must be recalled. If 468 the client cannot do this then the MDS cache cannot shrink which can cause the 469 MDS to fail. 470 default: true 471 services: 472 - mds_client
If we don't abort the client daemons it probably will cause the MDSs to fail.
