Exadata存储节点的CPU限制成功了没?

上篇随笔谈到刷1/8 rack时,日志显示存储节点已经成功限制CPU的,可如果使用mpstat命令看貌似还是64 CPU,难道实际没有成功吗?

[root@dbm08celadm03 ~]# mpstat
Linux 4.14.35-1902.306.2.1.el7uek.x86_64 (dbm08celadm03.oscbj.com) 	2021年06月07日 	_x86_64_	(64 CPU)

10时50分22秒  CPU    %usr   %nice    %sys %iowait    %irq   %soft  %steal  %guest  %gnice   %idle
10时50分22秒  all    3.39    0.01    2.21    0.00    0.00    0.00    0.00    0.00    0.00   94.39

别急,我们实际去查询/proc/cpuinfo信息,发现已经是32个processor:

[root@dbm08celadm03 ~]# grep processor /proc/cpuinfo
processor	: 0
processor	: 1
processor	: 2
processor	: 3
processor	: 4
processor	: 5

processor	: 36
processor	: 37
processor	: 38
processor	: 39
processor	: 48
processor	: 49
processor	: 50
processor	: 51
processor	: 52
processor	: 53
processor	: 54
processor	: 55
[root@dbm08celadm03 ~]#
[root@dbm08celadm03 ~]# grep processor /proc/cpuinfo |wc -l
32

进一步使用cellcli查询存储节点的详情:

[root@dbm08celadm03 ~]# cellcli

也可以看到“cpuCount:”显示为“32/64”,说明存储节点的CPU是限制成功的。
