Can lfsck be run multiple times using different set of options (options like -l -c and -d ) using the same set of mds and ost db's. For e.g what to expect if lfsck is run for coherence check after a MDS crash in the following order
1.lfsck with -n (no fix) 2.lfsck to backup orphaned objects (-l option) 3.lfsck to delete orphaned objects (will it find any after backup) 4.lfsck to create missing OST objects MDS inodes (-c option). In all the above runs same mdsdb and ostds's were used. Is it advisable/mandatory to recreate mdsdb and ostdb's again after a fix is done using lfsck. Can all the tasks mentioned above be accomplished in a single run (i.e. can -l -d -c be specified together)? -- Regards-- Rishi Pathak National PARAM Supercomputing Facility Center for Development of Advanced Computing(C-DAC) Pune University Campus,Ganesh Khind Road Pune-Maharastra
