NEW QUESTION # 64
One Logical Volume named lv1 is created under vg0. The Initial Size of that Logical Volume is 100MB. Now you required the size 500MB. Make successfully the size of that Logical Volume 500M without losing any dat a. As well as size should be increased online.
Answer:
Explanation:
The LVM system organizes hard disks into Logical Volume (LV) groups. Essentially, physical hard disk partitions (or possibly RAID arrays) are set up in a bunch of equal sized chunks known as Physical Extents (PE). As there are several other concepts associated with the LVM system, let's start with some basic definitions:
Physical Volume (PV) is the standard partition that you add to the LVM mix. Normally, a physical volume is a standard primary or logical partition. It can also be a RAID array.
Physical Extent (PE) is a chunk of disk space. Every PV is divided into a number of equal sized PEs. Every PE in a LV group is the same size. Different LV groups can have different sized PEs.
Logical Extent (LE) is also a chunk of disk space. Every LE is mapped to a specific PE.
Logical Volume (LV) is composed of a group of LEs. You can mount a file system such as /home and /var on an LV.
Volume Group (VG) is composed of a group of LVs. It is the organizational group for LVM. Most of the commands that you'll use apply to a specific VG.
Verify the size of Logical Volume: lvdisplay /dev/vg0/lv1
Verify the Size on mounted directory: df -h or df -h mounted directory name Use: lvextend -L+400M /dev/vg0/lv1 ext2online -d /dev/vg0/lv1 to bring extended size online.
Again Verify using lvdisplay and df -h command.
NEW QUESTION # 65
Your System is going to use as a Router for two networks. One Network is 192.168.0.0/24 and Another Network is 192.168.1.0/24. Both network's IP address has assigned. How will you forward the packets from one network to another network?
Answer:
Explanation:
echo "1" >/proc/sys/net/ipv4/ip_forward
vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
If you want to use the Linux System as a Router to make communication between different networks, you need enable the IP forwarding. To enable on running session just set value 1 to
/proc/sys/net/ipv4/ip_forward. As well as automatically turn on the IP forwarding features on next boot set on /etc/sysctl.conf file.

07. Configure NTP
Configure your system to synchronize with the NTP server of materials.example.com (Note: materials.example.com is an alias for classroom.example.com).
Answer:
Explanation:
Solution:
# Install the chrony service for configuring NTP server
[root@node1 ~]# yum -y install chrony
[root@node1 ~]# vim /etc/chrony.conf
server materials.example.com iburst
[root@node1 ~]# systemctl restart chronyd
[root@node1 ~]# systemctl enable chronyd
# Check
# Set an arbitrary time
[root@node1 ~]# date -s "1982-1-1"
Fri Jan 1 12:00:00 AM EST 1982
# Restart the NTP server
[root@node1 ~]# systemctl restart chronyd
# Check if the time is synchronized
# Execute after 3-5 seconds, too fast won't synchronize the time
[root@node1 ~]# date
Tue Dec 12 11:40:19 PM EST 2023
# Use the chronyc command to check synchronization status
[root@node1 ~]# chronyc sources -v
