I’ve recently been evaluating iSCSI target drivers on my Mac. I tried several and I won’t bore you with those details but one, iSCSI Initiator X from KernSafe, did cause some issues following the evaluation. I wanted to capture the steps I needed to follow when I noticed severe performance issues following my evaluation period.
Continue readingI am providing support for Solaris Cluster again and have am now on a Mac (Hacintosh) using Vmware Fusion for my virtualization. Before you proceed with this tutorial, you must first install socat on the Mac as it is used to perform the console I/O redirection. I suggest using homebrew:
brew install socat
I recently had to upgrade our home network wifi to accommodate the growing number of smart devices needing network access. Continue reading
This is a compilation of several posts I found while researching this procedure and I wanted to save the steps. I’m sure I’ll need them again.
My “MAC” is running 10.10.5 and the NFS server is Ubuntu Linux 14.04 with ZOL.
I recently had the need to install systemtap on one of my CentOS 7 VMs and the process isn’t as straight forward as it should be. It seems not all packages needed are built for all revisions of the kernel. After much searching, I managed to get this working and wanted to archive this procedure.
I wanted to capture the changes which need to be done to a fresh centos7 server install to support Oracle 12C. The server was installed with Basic Server using a 4GB swap device but before we can start the Oracle install, we need to prepare the system.
I recently had the need to update my shiny new FreeBSD jailed server because I wanted to migrate to WordPress. I didn’t want to bring down the existing server while I did the install and converted my content so I managed to clone my existing jailed server using warden:
warden export name_of_jail --dir=/directory_for_warden_file This will take a while… Once done, you can import the warden file creating a new jail:
warden import jail_warden_file.wdn --host=jailbird --ipv4=192.168.1.105/24 You’ve now got a cloned jail and a template for creating other jailed servers.
If you need to a Solaris 11.x install which will use Solaris Volume Manger and want the metadbs on the boot disk, here’s a procedure to get the job done.

Solaris 11 network stack is using crossbow so network administration is completely different now. In order to switch from DHCP to a static IP, we need to do the following:
# netadm enable -p ncp DefaultFixed # ipadm create-ip net0 # ipadm create-addr -T static -a 192.168.1.21/24 net0/v4
rolemod -K type=normal root
pfexec pkg install --accept solaris-desktop
If the installadm client fails to boot and you land at the grub prompt, you may be missing next-server directive in the dhcp configuration. This should follow the filename directive.
# vi /etc/inet/dhcpd4.conf
...
host 08002746E9C3 {
hardware ethernet 08:00:27:46:E9:C3;
if option arch = 00:00 {
filename "0108002746E9C3.bios";
} else if option arch = 00:07 {
filename "0108002746E9C3.uefi";
}
next-server 192.168.2.1;
}
A VirtualBox Solaris Cluster complete with shared storage and quorum disk!
The host system is a Mac running 10.8:
Intel Core i7-3770K Ivy Bridge 3.5GHz
16Gb RAM

At the time of this article, I’m running Mac OSX 10.8.2 with VirtualBox 4.2.6. The Solaris Cluster is 3.3 running in a Solaris 10u10 virtual machine.
