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 ----------------------------------------------

Has anyone else experienced this?
