Redhat Cluster is a nice HA product. I have been implementing it for a while now, lecturing about it, and yes – I like it. But like any other software product, it has few flaws and issues which you should take under consideration – especially when you create custom “agents” – plugins to control (start/stop/status)…
This is not a simple task. Adding or compiling modules is a tricky feat when it comes to 2.4 kernels. It requires you compile the entire kernel yourself before. I have used a diskless machine, with an NFS mount as the place where I have kept all persistent data. Mounted it at /tmp/mnt directory. Preparations…
I encountered an interesting bug/feature of RHCS on RHEL4. A snip of my configuration looks like this: <resources> <fs device=”/dev/mapper/mpath6p1″ force_fsck=”1″ force_umount=”1″ fstype=”ext3″ name=”share_prd” mountpint=”/share_prd” options=”” self_fence=”0″ fsid=”02001″/> <nfsexport name=”nfs export4″/> <nfsclient name=”all ro” target=”192.168.0.0/255.255.255.0″ options=”ro,no_root_sqush,sync”/> <nfsclient name=”app1″ target=”app1″ options=”rw,no_root_squash,sync”/> </resources> <service autostart=”1″ domain=”prd” name=”prd” nfslock=”1″> <fs ref=”share_prd”> <nfsexport ref=”nfs export 4″> <nfsclient ref=”all ro”/>…
I have been quiet during the last few days as I was playing with WordPress Mu as a solution for containing several WordPress sites, with one management interface. This is an amazing product, and following my implementation, about 18 blogs are already there. My site required some special handling. As you know, my URL was…
As of today, I have switched back to using akismet and not the “Yawasp” plugin which was theoretically amazing, but as it seems – blocked too many legitimate comments, and allowed spam (only a little, but still). So you can feel free to comment whenever and however you want. I was disconnected for too long…
I was required to create a self-contained, single DVD to automate the installation of Solaris 10 on x86_64. I could not find any up-to-date straight forward guide which can explain how to do it, so I do it here. This is not an explanation for dummies, so you must know (to some degree, of course)…
