I am trying to find out why boniee++ is choking at the creating files sequentially and deleting sequentially on cephfs. I enabled mds debug for about 30 seconds and I find a bunch of lines like the following: 2015-05-19 15:54:12.930829 7f6de4ecf700 1 -- 192.168.40.3:6800/461756 --> 192.168.40.100:0/1741116310 -- client_caps(grant ino 10000004ca9 19656 seq 2 caps=pAsxLsXsxFsxcrwb dirty=- wanted=pAsxXsxFxwb follows 0 size 0/4194304 ts 1 mtime 2015-05-19 15:54:09.098825) v5 -- ?+0 0x557a800 con 0x4fdeca0 Is this statement showing that it takes 4 seconds to create an inode? Watching ( watch --interval=.2 -d 'ceph df') ceph df, rados df, and ceph osd pool stats seems to show that an object is being created or deleted about every 4 seconds. The test is now running for over 24 hours with the following bonnie++ comand: ~/bonnie++-1.03e/bonnie++ -u root:root -s 256g -r 131072 -d /cephfs/ -m CephBench -f -b I can give more log output if needed.
