Why is storage resized when changing instance type
Hi,
could someone explains me rules for resizing instance storage when changing instance size?
I have not found any rules when this happens and when not. Mostly yes, but had cases when not, if I'm not mistaken.
Nevertheless it's really "unfriendly" when we have to shrink all storages after changing instance size.
Thanks
Pavel

Hey Pavel. This is a new change we recently introduced, and it occurs if the following criteria are met:
1) The destination plan has a larger amount of disk space than the current plan. For example, if you are upgrading from a 2 GB to a 4 GB Linode plan.
2) The Linode’s disk configuration is simple:
1 disk of type ext 4 or ext 3 and 1 disk of type swap
OR
1 disk of type ext 4 or ext 3
You can prevent the auto resize by adding a small disk (just a few MBs) to your Linodes. By having three disks on your Linode you will stop the system from auto resizing.
This is covered in our resize guide under step 5. I'll also pass along your feedback to our team to see if we can make this more clear or if we can change how it works.
