how to activate a volume group

Using the magic of the "lt_hotswap" module, I can remove the cdrom in my T42's ultrabay. It gets removed from the IDE sub-system, and I can then insert my spare hard disk.

Laptop ultrabay hotswap driver version 0.3.1
lt_hotswap: '\_SB.PCI0.LPC.EC.BAT1' found (Hot-Swappable)
lt_hotswap: '\_SB.PCI0.IDE0.SCND.MSTR' found (Hot-Swappable)
lt_hotswap: '\_SB.PCI0.PCI1.DOCK.IDE1.PRIM.MSTR' found (Non-Swappable)
lt_hotswap: '\_SB.PCI0.LPC.FDC.FDD0' found (Hot-Swappable)
lt_hotswap: '\_SB.PCI0.PCI1.DOCK' found (Hot-Swappable)
lt_hotswap: Requesting IDE eject!
lt_hotswap: Attempting to eject

So, I ran my normal script that mounts partitions by LABEL= and it complained that my /dev/MaraUltraBay/* files weren't there. Oops. Where is the volume group?

After some futzing, I learned that I did to run:

marajade-[~] root 179 #vgchange -a y MaraUltraBay
  11 logical volume(s) in volume group "MaraUltraBay" now active

marajade-[~] root 181 #lvs
  LV                 VG           Attr   LSize    Origin Snap%  Move Log Copy%

  ProjectThintropy   MaraUltraBay -wi-a-    3.00G
  ProjectVpnx        MaraUltraBay -wi-a-    2.00G

  ProjectsMisc       MaraUltraBay -wi-a-    2.00G
  ProjectsOpenswan2  MaraUltraBay -wi-a-    4.00G
  UMLROOT2           MaraUltraBay -wi-a-    2.00G

marajade-[~] root 183 #/root/etc/sswboot start

Now, really, this needs to be driven by the hotplug system. I wish that it wasn't quite as many twisty shell scripts... all alike.

Now work for XDS Canada

Three weeks ago I accepted a position as Director, Consumer Desktop Development at Thintropy Inc. Today, it was announced that XDS, Inc, of Durham, NC acquired Thintropy.

See: http://www.prleap.com/pr/76656/

I can't tell you much about what we are doing, but it doesn't involve IPsec. It does involve Linux, and I'm excited about it.

(No surprise here. It took the lawyers something like 12 weeks to finalize the deal...)

I continue to work 1/2 time at VP R&D of Xelerance Corporation. Xelerance has a number of security related products in development, which will be announced in June. Xelerance continues to provide 3rd level support for IPsec, and I will continue to hack on Openswan on a regular basis.

Cartoon U giving away drugs to students

From:

http://msdnaa.carleton.ca/

Carleton University student access for the MSDNAA software.

The MSDN Academic Alliance is an annual membership program for departments that teach and utilize technology such as Computer Science, Engineering, and Information Systems departments. The membership provides Microsoft software to keep academic labs, faculty and students on the leading edge of technology. With this membership, students who's departments have enrolled in the program will have the latest Microsoft development tools, operating systems, server software, documentation, and technical references available to them.

Student Requirements

Requirements for you to acquire Microsoft software online:

* the department of the course that you are enrolled in must be a member of the MSDNAA,

* meet the requirements set by Microsoft and your department; the Microsoft requirements are based on courses taken at Carleton University.

Please make sure to read the Microsoft Student User Agreement for the MSDNAA software. The departments that have enrolled in the online distribution of MSDNAA software are listed below.

So, the students who most need to be exposed to well designed systems are being fed junk.
