Extend LVM with a new disk

partprobe 
cat /proc/partitions - note the un-partitioned drive (ex: there is a /dev/xvdX but not /dev/xvdX1) 
cfdisk /dev/xvdX - create new partition, type 8e (LVM) 
pvcreate /dev/xvdX1 
vgdisplay  - note the VG name (in my case is "vg_bkp_vol_1")
vgextend vg_bkp_vol_1 /dev/xvdX1 
pvscan 
lvdisplay  - note the LV path (here "/dev/vg_bkp_vol_1/lv_bkp_vol_1")
lvextend /dev/vg_bkp_vol_1/lv_bkp_vol_1 /dev/xvdX1 
lvdisplay 
vgdisplay

Phone extension that rings multiple external numbers (CCME Asterisk)

Skip to end of metadata
In this example we want to ring all the external numbers of a few people only by dialing extension 3331.
1: Connect to CCME and create a new dial-peer:
dial-peer voice 3331 voip
 description External Emergency Responders
 destination-pattern 3331$
 session protocol sipv2
 session target ipv4:192.168.0.XXX #(the Asterisk box)
 dtmf-relay rtp-nte cisco-rtp
 codec g711ulaw
 no vad
2: Connect to the asterisk server and add the extension in the default [incoming_context] in /etc/asterisk/extensions.conf: (192.168.0.YYY is the outgoing trunk)
exten => 3331,1,Dial(SIP/5145555555@192.168.0.YYY&SIP/51455555519@192.168.0.YYY&SIP/5145555552@192.168.0.YYY&SIP/5145555553@192.168.0.YYY&SIP/5145555554@192.168.0.YYY&SIP/5145555555@192.168.0.YYY)
exten => 3331,n,Hangup
3: Reload asterisk config and test the extension (smile)

Limit number of unix logins

if [ $number -ge $limit ]; then
echo "No more logins / Il n'y a plus de login. You are already logged as:

sleep 5
exit 0

Forward all emails from one sendmail to another

- in sendmail.cf change Djdomain.tld to something like Dj_subdomain.domain.tld Do the same thing for DMdomain.tld
- in the same sendmail.cf look for Fw or Fw-o and check the file it refers to (usually /usr/lib/mail/local-host-names); in that file remove the line stating "domain.tld" (in fact, remove everything, leave just _subdomain.domain.tld there), that way sendmail will know that it is not the default destination for the @domain.tld

- if necessary, create /home/$username/.forward (chmod 600, chown $username:$group) and put the right info in it

Dell Latitude Keyboard light

The backlit keys interface seems to be broken, so you need to mask the controlling service: systemctl mask systemd-backlight@leds\:dell\:\:kbd_backlight.service
then go to BIOS and and change the keyboard led timeout from 10s to 5s for AC Power and Battery mode - "For some reason if the kbd_backlight service is not masked, it somehow forces the bios led timeout back to 10s, and then the keyboard led always remains lit."
