Extending a logical volume at LVM

Suppose that we have a volume group named VG-TEST and It contains a logical volume named LV-TEST. After adding new physical disk /dev/sdx , we want to give additional 100G space to the LV-TEST logical volume. Following procedure is applied to the server.

In our linux server we have to create a new partition on the disk /dev/sdx.
# fdisk /dev/sdx
fdisk utility asks for parameters so that we create a new partition sdx1

To create physical volume
# pvcreate /dev/sdx1

To add physical volume to the volume group VG-TEST
# vgextend VG-TEST /dev/sdx1

To extend the logical volume LV-TEST
# lvextend -L+100G /dev/VG-TEST/LV-TEST
+100G means that we add extra 100G to the logical volume

We extended the logical volume. Now we should give this space server’s ext3 file system to use it.
# ext2online /dev/VG-TEST/LV-TEST

Creating Multiple VLANs over Bonding Interfaces with Proper Routing on a Centos Linux Host

In this post, I am going to explain configuring multiple VLANs on a bond interface. First and foremost, I would like to describe the environment and give details of the infrastructure. The server has 4 Ethernet links to a layer 3 switch with names: enp3s0f0, enp3s0f1, enp4s0f0, enp4s0f1 There are two bond interfaces both configured as active-backup bond0, bond1 enp4s0f0 and enp4s0f1 interfaces are bonded as bond0. Bond0 is for making ssh connections and management only so corresponding switch ports are not configured in trunk mode. enp3s0f0 and enp3s0f1 interfaces are bonded as bond1. Bond1 is for data and corresponding switch ports are configured in trunk mode. Bond0 is the default gateway for the server and has IP address 10.1.10.11 Bond1 has three subinterfaces with VLAN 4, 36, 41. IP addresses are 10.1.3.11, 10.1.35.11, 10.1.40.11 respectively. Proper communication with other servers on the network we should use routing tables. There are three
