My question is more along the lines 'Is an "fs fail" destructive?' It is not but lingering clients will not be evicted automatically by the MDS. If you can, unmount before doing `fs fail`. A journal flush is not really necessary. You only should wait ~10 seconds after the last client unmounts to give the MDS time to write out to its journal any outstanding events. > , that is, will an FS come up again after > > - fs fail > ... > - fs set <fs_name> joinable true Yes. -- Patrick Donnelly, Ph.D. He / Him / His Principal Software Engineer Red Hat, Inc.
