Dear Ceph, Thanks for your answer before. That let me learn more. Recently,I want to check the pools and the contents in the rados gateway. So I execute "rados lspools". Here is the massages on the screen: ============================ [root@mon1 ~]# rados lspools data metadata rbd .rgw ^^^^^^^^^^^^^ .users.uid .users .pool ^^^^^^^^^^^^ .log test2 test741 test741-2 test741-3 test741-4 test741-5 test1 doki1 123 foo anny =========================== I am curious about the information about .rgw .pool and .log。 ^^^^^ ^^^^^^ Therefore I execute "rados -p .rgw ls" Here is the massages: ================= [root@mon1 ~]# rados -p .rgw ls .log .pool .users .users.uid test1 test2 test741 test741-2 doki1 test741-3 test741-4 test741-5 123 ================= Question(1): What is that massages that mean? What is the difference between the massages will be showed when I type "rados lspools"? When I execute "rados -p .pool ls" Here is the massages: ================= [root@mon1 ~]# rados -p .pool ls 10 11 13 14 15 17 18 19 20 21 6 12 9 ================= Question(2): What is the number mean? Question(3): Likewisethe same questions above-mentioned,What is the messages mean when I type " rados -p .log ls" ? Thank you~ Best Regards.
