CentraLUG, 2 April 2007: Bill Stearns on Logical Volume Management

The monthly meeting of CentraLUG, the Concord/Central New Hampshire chapter of the Greater New Hampshire Linux Users Group, occurs on the first Monday of each month on the New Hampshire Institute Campus starting at 7 PM.

This month, we’ll be meeting in our usual location, Room 146 of the Library/Learning Center/Bookstore, http://www.nhti.net/nhtimap.pdf , marked as “I” on that map. Directions and maps are available on the NHTI site at http://www.nhti.edu and on the GNHLUG site at http://wiki.gnhlug.org/twiki2/bin/view/Www/DirectionsToCentraLUG. The
main meeting starts at 7 PM, with Bill Stearns presenting LVM: Logical Volume Management. Open to the public. Free admission. Tell your friends.

Bill is an authority in the field of security, an instructor for the SANS Institute and an activist in several anti-spam efforts. Visit
http://www.stearns,org for a list of some of the interesting projects he’s been working on and packages he maintains. At April’s meeting, Bill will explain the infrastructure of LVM and how to work with it. LVM is a great technology that allows you to add disk space to running systems, manage the mapping of logical and physical volumes and manipulate disk usage. With the correct choice of hardware and file systems, much of the work can be done while the systems continue to run! Bill has some practical insights into how these systems work, and can talk about some of the subtleties of why you might choose LVM-atop-RAID vs. RAID-atop-LVM. Attendees are encouraged to bring laptops: using temporary space (no need to repartition), Bill will use some loopback tricks to let you create some devices and manipulate the LVM commands – a great hands-on experience!

More details at about this meeting and the group are available at http://www.centralug.org and http://www.gnhlug.org as I learn them!

In future meetings, we are looking forward to Ben Scott demoing OpenWRT (May) and Seth Cohn showing off Drupal (June) – dates and times not yet confirmed and in flux, so stay tuned. Hope to see you there!
