We have currently a strange behaviour on our gluster 3.3 volume (4 bricks, distributed+replicated). From time to time the cpu usage increases to around 50% and the gluster daemon starts responding. After some research I got a pointer to a bug report (https://bugzilla.redhat.com/show_bug.cgi?id=838784). We use kernel 3.2.0-26-generic on Ubuntu 12.04, so I'm afraid we are affected. I used the test script, but I'm not able to interpret the results correct. root@foo:~# ./test /data/brick0/instances/_base/ 496e4306f1de9b647fc0a6021b35fd5428e88c70_10: 495888329 (495888329) ..: 616848399 (616848399) .: 723397576 (723397576) fc9ab12b1551f9c358b5acd65e8fcbe197c89f6c: 752979281 (752979281) ephemeral_0_40_None: 995810121 (995810121) 496e4306f1de9b647fc0a6021b35fd5428e88c70: 2147483647 (2147483647) Does that mean I'm affected by the ext4 bug? If not, what can I do to gather enough information to open a new bug report? Regards, Chris
