Women in Technology

I ran across a simple use case that wasn't explicitly covered in the article, but I was able to piece together the required commands from various examples in the article. I thought I'd share concisely.

Given:

• A single disk (/dev/sda), partitioned to a Physical Volume (/dev/sda2) in an active Volume Group (VolGroup00), and allocated to a Logical Volume (/dev/VolGroup00/LogVol00)


• An active filesystem (ext3) mounted (/) on that Logical Volume, where more disk space is required


• No RAID involved

Wanted:

• To add disk space (/dev/sdb) to the mounted filesystem (/)

Procedure:

• Partition the disk (/dev/sdb1), mark as type 8e
  
# fdisk /dev/sdb

  


• Create the physical volume
  
# pvcreate /dev/sdb1

  


• Extend the volume group by adding the new physical volume
  
# vgextend VolGroup00 /dev/sdb1

  


• Check the new volume group size
  
# vgdisplay | grep "VG Size"

  


• Extend the logical volume to the new total available
  
# lvextend -L 28G /dev/VolGroup00/LogVol00

  


• Find the filesystem mount point
  
# mount

  


• Perform an online resize of the filesystem to the max available
  
# ext2online -v /dev/mapper/VolGroup00-LogVol00

  


• Now check your disk free
  
# df -h
