Hi Nicola, You might want to post in the ceph-dev list about this or discuss it with devs in the ceph-devel slack channel for quicker help. Bests, Frédéric. ________________________________ De : Nicola Mori <mori@fi.infn.it> Envoyé : mercredi 21 août 2024 15:52 À : ceph-users@ceph.io Objet : [ceph-users] Re: Pull failed on cluster upgrade The upgrade ended successfully, but now the cluster reports this error: MDS_CLIENTS_BROKEN_ROOTSQUASH: 1 MDS report clients with broken root_squash implementation From what I understood this is due to a new feature meant to fix a bug in the root_squash implementation, and that will be released with version 19. I didn't find anything about a backport to 18.2.4. Can someone share some info please? Especially about if and how it can be fixed. Thanks in advance, Nicola
