I am finding that traditional SATA drives are not keeping up with the amount of Virtual Machines I'm throwing down. Especially with one or more WindowsXP guests, the aggregated disk i/o is overwhelming my host. So, out comes my old SCSI Array with 3x 36GB 10k drives. Let's compare... |

The future of commodity hardware may be UEFI, but as I see it there are some draw backs for the home user. Example: I have been using some form of software RAID at home for as long as I can remember and when used with a traditional BIOS, it is fairly straight forward. Your options are: raid-tools (mdadm), dm-raid (integrated with onboard hw RAID) & lately even LVM. So what's the downside of UEFI? |

This is the first attempt at installing Red Hat Enterprise Linux 6 on a UEFI enabled system. If you are interested in learning about UEIF, you might start with this Red Hat Summit 2011 session on "Using GPT with Storage Devices". Otherwise, read on and follow self-educating process... |

The primary site (http://www.linuxsoup.com) has now been migrated to a new home. Unfortunately it fell stagnant during the past few years as people moved, services moved, jobs changes, etc... But alas, as soon as the DNS changes fall in to place the site should be fully operational again. |

Over the last couple of weeks, smartd has begun logging a flurry of "Currently unreadable (pending) sectors" messages. When this particular host was deployed, I elected to use LVM mirroring (not mdadm or dmraid) for data redundancy. Here are the basic steps I followed to do some basic tests and ultimately replace the failing device. |

In recent months (6 months ago?) I upgraded the HP dv4-2155dx with a Intel Core i5, additional memory (8 GB total) & Fedora 14. Now I'm curious what the net benefit has been. Reportedly, the Core i5 benefits from turboboost and a few other i7 features. I have everything working this time, including the multi-format SD card. Read on for full details... |
