Seacoast LUG 10-Sept-2007: Ben Scott on RAID and LVM

  • What : RAID and LVM storage management
  • Date : Mon 10 Sep 2007 (TONIGHT)
  • Time : 7 PM to 9 PM
  • Where: Room 301, Morse Hall, UNH, Durham, NH

For the September 2007 SLUG/Seacoast/UNH/Durham meeting, Ben Scott
will be speaking on storage management using RAID and LVM.

=== About the presentation ===

RAID (Redundant Array of Independent Disks) and LVM (Logical Volume
Manager) let you do more with your disks than create partitions and
filesystems. With RAID, you can combine disks to make larger
filesystems, and/or add redundancy to help protect against disk
failure. LVM takes that a step further, by letting you create
arbitrary Logical Volumes (to hold filesystems), which can be easily
reallocated, resized, moved, and copied (snapshots).

Ben will be talking about some of the concepts, review the tools and
techniques available, and (hopefully) doing a live demonstration of
some of the things you can do. The specifics will be flexible, in
response to attendee demand.

=== About the speaker ===

Ben is a local Linux user, enthusiast, and advocate. He handles the
care and feeding of the GNHLUG Internet server, and is a GNHLUG
Bored^W Board Member.

=== About SLUG ===

SLUG is the Seacoast Linux User Group, and is a chapter of GNHLUG,
the Greater NH Linux User Group. Rob Anderson is the SLUG
coordinator. SLUG meets the second Monday of every month, same time,
same place. You can find out more about SLUG and GNHLUG at the and websites.

Meetings take place starting at 7:00 PM. Meetings are open to all.
The meeting proper ends around 9ish, but it’s not uncommon to find
hangers-on there until 10 or later. They take place in Room 301 (the
third floor conference room), of Morse Hall, at the University of New
Hampshire, in Durham.

Schedules Direct supplies TV/cable schedules for MythTV users

“Schedules Direct is a non-profit organization that provides raw U.S./Canadian tv listing data to Free and Open Source Applications. Those applications then use the data to provide things like PVR functionality, search tools, and private channel grids.” Recently, the Tribune Media Services company Zap2It decided to discontinue their free service that had  provided TV/cable schedules to home hobbiests. Schedules Direct was formed by advocates for the various home-brewed PVRs to step in and supply the content. After negotiations with a number of vendors, they ended up back with TMS as their supplier. In a matter of weeks, the Schedules Direct crew managed to set up the infrastructure to provide a 10-day trial membership, a paid subscription service ($15/3 months initially, with a goal of $20/year or less once they establish the viability of the service) and a working infrastructure. Users of MythTV need to upgrade to the most recent (v 0.20.2 or later) version and change their configuration to use the new service. I switched over the weekend, confirmed I could read the new schedules, and paid up for the first three months. What a great example of the community coming together to supply their own needs.

GNHLUG has had several MythTV meetings, and I anticipate more in the future. Jarod Wilson presented a very popular session at the Merrimack Valley Linux User Group last year, and that lead to an effort by Jarod and maddog and others to run a series of MythTV installfests at NHTI.
