Hi, I have a strange problem. I am using glusterfs 3.0.5 on 3 machines with CentOS 5.4. If I am using the mounted glusterfs intensively it is using more and more cache. I think it is normal. But as more and more cache used, it's getting slower and slower. The glusterfsd process uses 500-700% CPU (normal 1-10%, btw it's a 8 core machine). On the mounted glusterfs a simple directory change takes about half minute, and every operation very very slow on the mounted glusterfs. If i execute the following command: sync && echo 3 > /proc/sys/vm/drop_caches Almost the entire system memory freed, and glusterfsd CPU usage fall back 1-10%, and everything working fine.. for a while Now, i have to put this command into cron for every night. Has someone encountered the same problem? Is there any other solution? Regards, Adam Koleszar
