Re: [Gluster-users] Memory leak with glusterfs NFS on 3.2.6

[Xavier Normand]

Hi Philip, I do have about the same problem that you describe. There is my setup: Gluster: Two bricks running gluster 3.2.6 Clients: 4 clients running native gluster fuse client. 2 clients running nfs client My nfs client are not doing that much traffic but i was able to view after a couple days that the brick used to mount the nfs is having memory issue. i can provide more info as needed to help correct the problem. Thank's Xavier Le 2012-06-12 à 08:18, Philip Poten a écrit : 2012/6/12 Dan Bretherton <d.a.brether...@reading.ac.uk>: I wonder if this memory leak is the cause of the NFS performance degradation I reported in April. That's probable, since the performance does go down for us too when the glusterfs process reaches a large percentage of RAM. My initial guess was that it's the file system cache that's being eradicated, thus iowait increases. But a closer look at our munin graphs implies, that it's also the user space that eats more and more CPU proportionally with RAM: http://imgur.com/a/8YfhQ There are two restarts of the whole gluster process family visible on those graphs: one a week ago at the very beginning (white in the memory graph, as munin couldn't fork all it needed), and one yesterday. The drop between 8 and 9 was due to a problemv unrelated to gluster. Pranith: I just made one dump, tomorrow I'll make one more and mail them both to you so that you can compare them. While I just restarted yesterday, the leak should be visible, as the process grows a few hundred MB every day. thanks for the fast reply, Philip _______________________________________________ Gluster-users mailing list Gluster-users@gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
