hi all , i want to find out how ceph osd daemon start , first i use "mkcephfs" to initialize the osd data directory , i found that there are some files and directories (commit_op_seq meta nosnap omap) in current directory , but no pg directories , then i start ceph osd daemon , pg directories are created , but i do not know when and where these pg directories are created , can someone tell more details about how these pg are created and where i can locate the code of pg creation? any tips will be appreciated. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
