Removing files with find, and LVM snapshots

Posted 04-24-2012 at 11:21 AM by sag47
Tags find, lvm, snapshot

Take an LVM snapshot using a loopback device
Create the snapshot
Take a look at the devices in your volume group. First there needs to be sufficient space in the volume group for a snapshot to occur. Check this by typing: vgdisplay and checking for Free PE / Size
vgdisplay -v
Create a loopback device to use for the snapshot. My volume group is named vg_echo360. I want my snapshot to be 9.9GB in size so I'm creating a loopback device which is 10GB in size....

Here's a bit of Computer Mad Science that you might find interesting. Or at least amusing.

  • It may run in preview mode without even compiling it.
  • It may ONLY run in preview mode if you don't

I got online with Ubuntu 10.11

Posted 04-23-2012 at 10:04 AM by fred roellig

I got online with ubuntu 11.10 oneiric ocelot on my Dell Precision T3400. It has 2.0 GiB and Intel® Core™2 Duo CPU E8400 @ 3.00GHz × 2 and it is 32-bit. This is how I did it.

I started my computer and noticed the little triangle thingy (it's not technically a triangle, the top side is bowed out, more of an arc than a straight line) in the upper right hand corner of my computer screen didn't have any lines in it. I know from windows and mac that that means I'm not picking up any wireless...
