i am using the redhat cluster suite (luci and ricci) on my centos 5.3. i have 2 nodes in a cluster. when i poweroff the first node on wich a vm service is running, the service switchtes to node2. so far, so good :) but when i restart node1 the service is not failback to node1! i have created a failover domain with both nodes and priorized whre node1 has prio1 and node2 has prio2.
View 4 RepliesI am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.
View 9 Replies View RelatedI have just installed a two server cluster with ricci luci and conga on centos 5.6 32bit , both servers are vmware guests and have a shared storage disk connected to them both
with a GFS2 file system on them + fencing agents configured to work with VMware Vcenter.
(this is supported by vmware and works great on 4 other centos clusters i have been runing for 4 monthes with no CLVMD).
In this setup i used for the first time CLVMD as recommnded by RedHat so i could have the flexablitly of LVM under the GFS2 file system but , i have been getting some Strange problem with it , some times after a developer has done some IO heavy task like unziping a file or a simple TAR the load goes to 10 - 15 and no task can be killed , trying to reboot the server hangs.
After hard shutting the server every thing works ok until the next time some one does the same IO work as before.
This is my first post, and i have a question with the fence software for VMWare ESXi. The fence_vmware agent only works with ESX, and redhat (in you GIT repository) has submited a new agent called fence_vmware_ng that claims to work with ESXi. But the problem is that they do not specify the version that works with that. Anybody has test the fence_vmware_ng agent for VMWare ESXi 4.0 ?, i follow the instructions here: [URL]...and i can install the software, the API from VMWARE site, etc, but in the moment when i run the agent nothing happen, The agent connects to server, i see in logs, but the off-reboot-on operations not works. Only works status operations, that return the state of a virtual machine. I have CentOS 5.3 (fully today updated) with RHCS.

I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

View 1 Replies View RelatedI have added apache application into redhat cluster. If the apache process failed, it will cause the service group fail over. I want to disable the application monitoring. I search throung Internet and it depends on the apache init script. If I change /etc/init.d/httpd status always return 0(success). THe service group will not fail over even apache failed.
However, I want to remain the application monitoring but stop failover. If the application like apache failed, I want Redhat cluster to try restart the application like 3 or 4 times. If restart failed, it will not failover.
I was following [URL] for the cluster setup. But things dint work out. One Doubt to ask "Do I need the services cman, ccsd and rgmanager one at a time on the both machine. I have been running it through script.

I'm trying to build cluster computer system using redhat linux enterprise 5.5. And I'm on the step to set up the NFS mounting.

Copy iso image to head node on server and then install linux os on compute node via nfs.r2. Use my PC dvd drive to install linux on compute node via network.But I don't know how to do it.

After 5+ years of using Ubuntu, I am switching to it as my desktop. On my old FreeBSD desktop i was running KDE3; now I am runnung 10.04.1 and find that even tho things are more friendly with KDE4, one of the tools I use most,kttsmgr, no longer works like it did on my previous desktop.
How can I configure kttsmgr to use festival (right now it says "espeak") and to present the dialogue that prints the strings beneath what is being read? --Note that I downloaded flite and eflite for testing purposes. Both fail. not a peep. I do have audio with songs and can listen to streams, but nothing from ktts*

View 2 Replies View RelatedI have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
View 3 Replies View RelatedIm having a frustrating issue with my two machine cluster I setup using Conga. Everything was working great except now when lucci starts mysql the port (3306) is never opened to outside machines. I can do a "ps -ef | grep mysql" and see it running as well as login to mysql on the node it is running on - but an nmap of the machine does not show the 3306 port and I cannot login to mysql remotely and yes I turned off all iptables(iptables,ip6tables) and SElinux is disabled.What am I missing here? If I start mysql on my own (and it is using the same my.cnf as lucci is) it does show the port open and works perfect,t for some reason when lucci starts it, no dice

I need to install Cluster package and configure it on Dell Power Edge1950 intel Server on Red had linux 5 OS. how do i get cluster package for the same and configure it.
View 1 Replies View RelatedWe've been having lots of problems with burning CD-Rs on our Dell PowerEdge and T300 servers. We've had the CD recorders replaced frequently, and that often fixes the problem, but then we'll start having problems again. Usually it is the CD refuses to write, or it gets written but can't be read. Often, if I re-run the burn with the same blank CD, it will be fine.
I'd like to test some CD-Rs and compare error rates so I can recommend what CD-R media we should be using. Currently we are using Memorex and Verbatim CD-Rs. Is there a good cd recording/testing suite for Linux that I could use to do this?
