Rsync to a different ssh port

In order to use rsync with different ssh post, you can use -e flag, and supply ssh command with port option. For example, I want to transfer a file called /root/book.txt from a server called project.local with sshd running on port 55522 to local partition /mnt, I can use this command:

$ rsync -avz --progress -e "ssh -p 55522" root@project.local:/root/book.txt /mnt

where:
-a for archive mode
-v for verbose
-z to compress data during transfer
--progress for showing progress of the copy
-e to specify the remote shell to use, in this case to use ssh to port 55522

Resizing partition in centos after vmware hardisk extension

This is usually done, when the hardisk space for the CentOS VM is running low.

Check your current disk size

# fdisk -lu /dev/sda

To increase the size of the hardisk image, shutdown the centos VM

# poweroff

Increase the hardisk image in VMware

Power on the centos VM

Once logged in, check back whether you have increased your disk size

# fdisk -lu /dev/sda

Create new partition on the new disk space

# fdisk /dev/sda

Press:

n   {new partition}

p   {primary partition}

3   {partition number}

t    {change partition id}

8e {Linux LVM partition}

w  {write partition change to disk}

Reboot the vm

# reboot

Check the new partition

# fdisk -lu /dev/sda

Create physical volume (PV) on the new partition

# pvcreate /dev/sda3

Check list of PV

# pvs

Extend the current Volume Group (VG) to include the new PV, and check the new VG size

# vgextend centos /dev/sda3

# vgs

Extend the current Logical Volume (LV), and check the new size of logical volume 

# lvextend /dev/mapper/centos-root /dev/sda3

# lvs

Resize / partition

# resize2fs /dev/mapper/centos-root

Check the new size

# df -h /
