Hi? All: I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS. All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status. So I created a cluster "cluster" using RHCS ,added the two hosts into the cluster . created...

Hi all, Somebody knows when RHCS for CentOS 4 will be out??? -- CL Martinez carlopmart {at} gmail {d0t} com

I am having problems when using a Dell PowerVault MD3000 with multipath from a Dell PowerEdge 1950. I have 2 cables connected and mount the partition on the DAS Array. I am using RHEL 4.4 with RHCS and a two node cluster. Only one node is "Active" at a time, it creates a mount to the partition, and if there is an issue RHCS will fence the device and then the other node will mount the partition. I have now run into a problem twice where my ext3 (with Journaling) has corrupt inod...

Hello fellows, I have a problem with a 2 node RHCS cluster (CentOS 4) where node 1 failed and node 2 became active. That happened already last year and due to holidays the customer didn't recognize it. The cluster is just a failover for Apache and has no shared storage space. Customer now saw the situation, tried to fix it by rebooting node...

...on RHEL? I'm trying to create a more or less completely fault tolerant solution with two storage servers syncing storage with dual-primary DRBD and offering it up via multipath to nodes for OCFS2. I was able to successfully multipath a dual-primary DRBD based GFS2 volume in this manner using RHCS and GNBD. But switched to OCFS2 because GFS2 was very slow for file system commands. I'm currently exporting the OCFS2 volume to the nodes via iSCSI but, from what I've read, you can't multipath dual-primary DRBD over iSCSI without the risk of data corruption. I would appreciate any a...

Hi all, I''ve posted to the linux-cluster suite about a issue i''m having with RHCS and Xen, it seems all my DomU''s cant join the cluster, the answer i got was this ---------------------------- Ah, you''re running Xen! There''s a bug in cman_tool in that it only looks at the first 16 interfaces and Xen seems to stuff loads more in there. The attached p...

I want to set up a cluster that is used for web hosting (RHCS cluster). Recently, I experimented with a 2 node cluster and was able to run it successfully. However, I have started facing some issues with Apache, which I had configured as a service using the Cluster configuration tool. To do this Apache needs a floating IP address. This address is in addition...

We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like to turn them into some sort of highly available nfs file server. Currently, I am familiar with DRBD and RHCS but I was curious what others might recommend in such a situation. I'm not sure how easily we could use RHCS in such a situation because we don't really have the advantage of shared storage in this setup. We are strictly limited to the two boxes. Having said that, it would be nice to hav...

Hi Guys, I'm using centos 6.5 as guest on RHEV and rhcs for cluster web environment. The environtment : web1.example.com web2.example.com When cluster being quorum, the web1 reboots by web2.

...strip which you can control via serial interface to make each of the ports switch on and off independently). they work fine; i plug a DB-9 cable into the back of my machine, fire up minicom, and i have full control. however, my eventual plan is to use these as fencing devices for a small RHCS cluster i'm building, and so the fencing process will need to be scriptable. RHCS wants to fence by invoking a "/sbin/ fence_<whatever>" script that uses Net::Telnet to connect to the fencing device and then enters the commands. so, it seems that what i need is a telnet s...

Hi all, Can anybody inform me wether the "RedHat Certificate System" or actually a CentOS equivalent is available for CentOS. Just skimmed on a download site through the RPM's for 5.3 and I couldn't find it. According to their pressrelease, it the code should be gpl, allthough I can't find any rpm for RH, FC or Centos. It seems that this is one of the few CA-packages for
