Thank you John, I think about it. I did : # get inodes in pool rados -p my_pool ls | cut -d '.' -f 1 | uniq -u # returns 132886 unique inodes # get inodes in cephfs find . -printf 'ibase=10;obase=16;%i\n' | bc | tr '[:upper:]' '[:lower:]' # returns 7169 inodes But, I would like to be sure that inodes from rados pool are not linked in CephFS metadata somewhere... I don't know, it could be possible, no ? Is there a way to print "readable" CephFS metadatas ? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
