Best/Easiest way to expand the storage?

[Esfeld]

This is more of an Ubuntu question but I'm hoping others will find it helpful.  Our VM admins expanded the available disk, but restarting the system doesn't cause it to automatically use it.  What do I need to do?  Googling for it gave me too many answers.  Gparted, parted, expand2fs, etc.

Thanks!

• Create a new Disk via the ESXi manager and attach it to the VM (can be done with the image off)
• Start the VM
• vgdisplay (to see the name of the Volume Group. It should display “Expedition-vg”)
• sudo pvcreate /dev/sdb
• sudo vgextend Expedition-vg /dev/sdb
• sudo lvextend -l +100%FREE /dev/Expedition-vg/root (We request extending the volume with 100% of the available space)
• df -h (notice /dev/mapper/Expedition—vg-root) is 18.GB of size
• sudo resize2fs /dev/Expedition-vg/root
• df -h (notice /dev/mapper/Expedition—vg-root) increased its size

when I use the sudo pvcreate /dev/sdb command I get this error:

Device /dev/sdb not found (or ignored by filtering).

This seems to be related to the OS management, so maybe you could get some support from the VM manager or a Linux IT support in your team, in case you have doubts on the steps on how to add an additional device.

The issue you may be facing is that the new added unit in your case got a different label, and it is not called sdb. Make sure you are using the right label for your new added device. 

You can list the existing units via the following command:

sudo fdisk -l
