I am looking for hints about how to debug this:<br>
<br>
I have a 4x2 Distributed-Replicate volume which exhibits extremely slow<br>
operations. Example:<br>
# time stat /gfs/dl<br>
51969 10143657874486987692 drwxr-xr-x 4 _httpd wheel 172912968 4096 "Nov 13 17:22:12 2017" "Sep 22 11:53:35 2017" "Sep 22 11:53:35 2017" "Jan 1 01:00:00 1970" 131072 8 0 /gfs/dl<br>
8.72s real 0.00s user 0.01s system<br>
<br>
But the thing is not 100% reproductible. Sometime I get an isntant<br>
(normal) response.<br>
<br>
gluster volume status also exhibits trouble: each server will only<br>
list its bricks, but not the other's one. I suspect it could just<br>
be some tiemout because of slow answer from the peer.<br></blockquote><div><br></div><div>Have you checked the output of gluster peer status? Also does glusterd log file give any hint on time outs, rpc failures, disconnections et all?</div><div> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
tcpdump tells me that the server can take seconds to answer.<br>
Brick logs show nothing special.<br>
<br>
Any idea?<br>
