Fast debian / ubuntu bonding

On debian : HOWTO

There is just one different thing on Ubuntu , aliases becomes modprobe.d/bonding.conf. (it should work anyway I guess. )

root@fbmgrid01:/home/sgeadmin# cat /etc/modprobe.d/bonding.conf

alias bond0 bonding
options bonding mode=0 miimon=100

root@fbmgrid01:/home/sgeadmin# cat /etc/network/interfaces|grep -v ^#

auto lo
iface lo inet loopback

auto bond0
iface bond0 inet static
pre-up ifconfig bond0 up
pre-up ifconfig eth1 up
pre-up ifconfig eth0 up
up ifenslave bond0 eth1 eth0
down ifconfig eth1 down
down ifconfig eth0 down
down ifenslave -d bond0 eth1 eth0

And then just restart the network.


Extend lvm mount point in 3 minutes

Follow the steps:

1) Add your new disk (Virtual disk or physical LUN)

2) Find them:

echo “- – -” > /sys/class/scsi_host/host0/scan

3) Do a partition (type 8e=> LVM)

fdisk /dev/sdb
default =1

4) Create Physical Volume on partition

pvcreate /dev/sdb1

5) Add the PV to the Volume Group

vgdisplay # show your volume groups, I need to add sdb1 to fbmsvn01
vgextend fbmsvn01 /dev/sdb1

6) Add the new space on the VG to the Logical Volume(I add 5GB)

lvdisplay # shows your logical volumes , I need to extend /dev/fbmsvn01/var
lvextend -L+5G /dev/fbmsvn01/var

7) Resize the filesystem on the LV

resize2fs /dev/fbmsvn01/var # resize your partition, so it gets the new inodes. if it’s your root partition a backup may give you some peace.

8) done.

Extra documentation:

python -m SimpleHTTPServer

Serve current directory tree at http://hostname:8000.

If more than one is needed it is able to receive another port at the end.

python -m SimpleHTTPServer 8000
