Hi Vijay I have enabled client profiling and used this script https://github.com/bengland2/gluster-profile-analysis/blob/master/gvp-client.sh to extract data. I am attaching output files. I don't have any reference data to compare with my output. Hopefully you can make some sense out of it. On Sat, Jun 10, 2017 at 10:47 AM, Vijay Bellur <vbellur at redhat.com> wrote: > Wo...

Hi Vijay Did you manage to look into the gluster profile logs ?

...39;ll update if I found any corrections or new definitions. Btw, my previous underatanding about LOOKUP is wrong, its NOT dns lookup. Regards, Jeevan.

Hi Ben, do you know if the smallfile benchmark also does interleaved getdents() and lstat, which is what I found as being the key difference that creates the performance gap (further down this thread)? Also, wouldn't `--threads 8` change the performance numbers by factor 8 versus the plain `ls` and `rsync` that I did? Would you mind running those commands directly/plainly on your cluster to

Maybe not 8x but it will DEF improve things. I just recycled what was in my history buffer, I just wanted to illustrate that even though you see th...

Filtering the brick logs in TRACE mode with rpcsvc.c does show the FOPS. >From this, I've realized that LOOKUP is actually dns lookup. This actually differs from NFS lookup operation.

Hi, Can I get a brief description of all the FOPS in gluster or the location of the source code file so that I will try to get an understanding myself? Few FOPS I'm not clear like FORGET, UNLINK, FLUSH, LOOKUP Or is there a way I can tunnel through the FOPS that that are happening in the background for each operation? I have tried this to find from a brick logfile in TRACE mode, but there

Would it be possible for you to turn on client profiling and then run du? Instructions for turning on client profiling can be found at [1]. Providing the client profile information can help us figure out where the latency could be stemming from.

Hi Vijay Thanks for your quick response. I am using gluster 3.8.11 on Centos 7 servers glusterfs-3.8.11-1.el7.x86_64 clients are centos 6 but I tested with a centos 7 client as well and results didn't change gluster volume info Volume Name: atlasglust Type: Distribute Volume ID: fbf0ebb8-deab-4388-9d8a-f722618a624b Status: Started Snapshot Count: 0 Number of Bricks: 5 Transport-type: tcp

Tony?s performance sounds significantly sub par from my experience. I did some testing with gluster 3.12 and Ovirt 3.9, on my running production cluster when I enabled the glfsapi, even my pre numbers are significantly better than what Tony is reporting: ??????????????????? Before using gfapi: ]# dd if=/dev/urandom of=test.file bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824
