Using strace fixes hung memory issue

由 倾然丶 夕夏残阳落幕 提交于 2019-12-07 01:04:26
问题 I have a multithreaded process running on RHEL6.x (64bit). I find that the process hangs and some threads (of the same process) crash most of the time when I try to bring up the process. Some threads wait for shared memory between the threads to get created (I can see that all of it does not get created). But when I use strace , the process does not hang and it works just fine (all of the memory that is supposed to be created, gets created). Even interrupting strace after the memory gets

前言 最近IBM提供了一台powerpc给我们测试使用.在上面装出几个虚拟机,准备加入到云平台中. 同时为了监控主机状况,准备在上面安装nagios和ganglia. nagios的安装同x86_64环境下相差不多,但是ganglia的安装过程就稍微复杂些,写文记录如下. 学习笔记,以备查阅. @Author duangr @Website http://my.oschina.net/duangr/blog/183776 1. 相关环境 项 值 Issue Red Hat Enterprise Linux Server release 6.4 (Santiago) OS Linux 2.6.32-358.el6 Arch ppc64 2. 安装目标 目标是预先安装好ganglia所依赖的rpm包,后续就可以参考 ganglia的安装步骤 来具体安装. rpm -q gcc glibc glibc-common rrdtool rrdtool-devel apr apr-devel expat expat-devel pcre pcre-devel gcc-4.4.7-3.el6.ppc64 glibc-2.12-1.107.el6.ppc64 glibc-2.12-1.107.el6.ppc glibc-common-2.12-1.107.el6.ppc64 package

Docker - Creating base image with RHEL iso

由 ∥☆過路亽．° 提交于 2019-12-07 00:22:38
问题 I am trying to use a RHEL image for my project. Is there a way to create a base image with my RHEL 6's iso file? I am not using Fedora as it is beneficial for my project to use the RHEL distribution instead. 回答1: If you want a fair bit of control, you may want to look into the script in the Docker contrib repository on Github. One of them is for "yum" based images, Centos in this case, but there's no reason it shouldn't work for RHEL. It bootstraps itself through a series of YUM installs. If

How can I define the run order of vagrant middleware plugins?

由 可紊 提交于 2019-12-06 19:25:25
问题 I'm creating a Red Hat Enterprise Linux 7 VM in VirtualBox with vagrant. If I have a base box that both doesn't have the VirtualBox guest additions, and isn't registered, then I'd manually need to do the following: Register the box with subscription-manager Install guest additions The reason that I'd need to perform registration first, is that to install guest additions, I'd need to install some extra packages. Now, there are 3rd-party vagrant plugins for both of these tasks: vagrant

Deploying docker swarm without using docker machine

由 心不动则不痛 提交于 2019-12-06 19:24:01
问题 Currently I have a bunch of RHEL7 VMs running on RackSpace and want to deploy docker swarm for testing purpose. The Docker Docs only describes the method to deploy docker swarm by using docker machine. Question: Since VirtualBox cannot be used in VMs, are any other ways such that I can directly deploy docker swarm on my VMs without using docker machine? 回答1: In fact Docker documentation offers you how to set up a swarm cluster 'manually' without using docker-machine: Create a swarm for
