[Gluster-users] Missing 'status fd' and 'top *-perf' details
Hello everyone, I have the following situation. I put some read and write load on my test GlusterFS setup as follows: # dd if=/dev/zero of=file2 bs=1M count=3000 # cat file2 > /dev/null While doing the above I tried to gather some statistics and found out that 'status fd' doesn't really show anything and top read-perf/write-perf show only 0's. Here are the details: # gluster volume status myvolume fd FD tables for volume myvolume ---------------------------------------------- Brick : 10.12.10.7:/var/lib/glusterfs_disks/disk01/brick ---------------------------------------------- Brick : 10.12.10.8:/var/lib/glusterfs_disks/disk01/brick ---------------------------------------------- Brick : 10.12.10.9:/var/lib/glusterfs_disks/disk01/brick ---------------------------------------------- # gluster volume top myvolume write-perf Brick: 10.12.10.7:/var/lib/glusterfs_disks/disk01/brick MBps Filename Time ==== ======== === 0 /file2 2015-02-11 21:01:57.797129 0 /file2 2015-02-11 21:00:39.605479 0 /file1 2015-02-11 20:59:13.890372 0 /file2 2015-02-11 20:47:48.062088 0 /file2 2015-02-11 20:45:46.005462 0 /file 2015-02-11 18:25:19.961485 Brick: 10.12.10.8:/var/lib/glusterfs_disks/disk01/brick MBps Filename Time ==== ======== === 0 /file2 2015-02-11 21:01:40.369140 0 /file2 2015-02-11 21:00:22.180878 0 /file1 2015-02-11 20:58:56.464305 0 /file2 2015-02-11 20:47:30.646403 0 /file2 2015-02-11 20:45:28.593213 0 /file 2015-02-11 18:25:02.669979 Brick: 10.12.10.9:/var/lib/glusterfs_disks/disk01/brick MBps Filename Time ==== ======== === 0 /file2 2015-02-11 21:02:09.552385 0 /file2 2015-02-11 21:00:51.357701 0 /file1 2015-02-11 20:59:25.623650 0 /file2 2015-02-11 20:47:59.816884 0 /file2 2015-02-11 20:45:57.744475 0 /file 2015-02-11 18:25:31.733212 My setup is: # glusterfs -V glusterfs 3.5.3 built on Nov 17 2014 15:48:52 # gluster volume info Volume Name: myvolume Type: Replicate Volume ID: e513a56f-049f-4c8e-bc75-4fb789e06c37 Status: Started Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: 10.12.10.7:/var/lib/glusterfs_disks/disk01/brick Brick2: 10.12.10.8:/var/lib/glusterfs_disks/disk01/brick Brick3: 10.12.10.9:/var/lib/glusterfs_disks/disk01/brick Options Reconfigured: network.ping-timeout: 10 nfs.disable: on client.ssl: off server.ssl: off ? ?Has anyone else experienced this? ?Regards, -- Rumen Telbizov Unix Systems Administrator <http://telbizov.com> -------------- next part -------------- An HTML attachment was scrubbed...

[Gluster-users] Missing 'status fd' and 'top *-perf' details
Am I the only one experiencing this? Do you guys have proper statistics?
