[Gluster-users] Missing 'status fd' and 'top *-perf' details

[Rumen Telbizov]

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
