Tour de Chateau & LVM
Wednesday 31st July, 2013 @ 7pm (pre-meeting downstairs at 6pm)
Address Muttis upstairs (118 Elgin st, Carlton VIC)
Tour de Chateau
Malcolm Herbert presented a talk to do with video editing the Tour de France to capture all the helicopter views only. He did it by using filtering on the sound that the Helicopter motors make.
LVM
I gave a quick live demo of LVM snapshoting which I find useful.
Create snapshot
lvcreate -L5G -s -n rootsnap /dev/vg.lvm.sol/root
Do something risky ie: an upgrade
apt-get update; apt-get upgrade; apt-get dist-upgrade
Upgrade went ok? - Yes: Delete snapshot
lvremove /dev/vg.lvm.sol/rootsnap
- No: Revert to snapshot & reboot
lvconvert --merge /dev/vg.lvm.sol/rootsnap
reboot
