<div dir="ltr">I tested gluster nfs server with 1 nfs client. And run ltp's fs test cases on that nfs client. There seems to have 2 memory leak problem. (See my nfs server & 2 glusterfsd config file is in attach)<div>
The 2 problem describes below:<br><div><div><br></div><div>1. The glusterfs runs as nfs server exhaust system memory(1GB) in server minutes. After disable drc, this problem no longer exist.</div></div><div><br></div><div>
2. After disable drc, the test run 1 day with no problem. But I found glusterfsd used more than 50% system memory(ps command line output sees below). Stop the test can not release memory.</div><div><br></div><div><div>[root@server155 ~]# ps aux | grep glusterfsd</div>
