This is a very nice project I have been working on. The hardware at hand – two servers, with a shared SAS bus containing several SAS disks. Since it’s a shared bus, no RAID solution would cut it, and as I don’t want to waste disks with ASM (“normal” redundancy meaning half the size…), I…
Well, tricks is not the right word to describe advanced shell scripting usage, however, it does make some sense. These two topics are relevant to Bash version 4.0 and above, which is common for all modern-enough Linux distributions. Yours probably.

In the past I hacked around a problem with the order of starting (and with several bugs) a network stack combined of network bonding (teaming) + VLAN tagging, and then with network bridging (aka – Xen bridges). This kind of setup is very useful for introducing VLAN networks to guest VMs. This works well on…
Update to 0.2. Links remain the same. At the moment I cannot host many versions (it’s mostly uncomfortable), but this might change in the future. I have created a GUI cables installer and configurator for L2TP on Linux. I have noticed that there is no GUI solution, so, after this has been brought up, I…

This happened to me on HP EVA with HP StorageWorks Command…
