Hello! We've got one MDS (Lustre 2.0) with 4 processors (Intel(R) Core(TM)2 Quad CPU Q9500 @ 2.83GHz). Our CPU usage is HIGH - 80-100% . With top command we see: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2973 root 15 0 0 0 0 R 35.0 0.0 1509:09 socknal_sd02 2972 root 15 0 0 0 0 S 33.5 0.0 1132:13 socknal_sd01 2971 root 15 0 0 0 0 S 19.8 0.0 1129:12 socknal_sd00 2974 root 16 0 0 0 0 R 13.7 0.0 830:47.46 socknal_sd03
Is it normal situation? Can we improve performance at mds ? Maybe setting any parameters? (Only about 70 clients mount to Lustre and not all of them work with it.)
