[Question]: Multiple disks. How do I assign the disk type to multiple disks?

Is your question not already answered in the FAQ?

• I made sure the question is not listed in the FAQ.

Is this a general question and not a technical issue?

Question

First of all, does the environment variable name count in defining disks or is it just the order of lising inside the compose file that counts? So will DISKX_SIZE always correspond to /storageX (see below) ? And If I have multiple disks, how do I specify which disk is a growing qcow2 disk and which is a static disk?

environment:
  DISK_FMT: "qcow2"
  DISK2_SIZE: "32G"
  DISK3_SIZE: "64G"
volumes:
  - /home/example:/storage2
  - /mnt/data/example:/storage3

The order does not matter, it is the name that counts just like you say.

You currently cannot specify a different format for each seperate disk. So if you set it to qcow2 it will apply to all of them.

makes sense - thank you for clarifying!
And I guess adding a second disk later will not destroy any data on the first disk defined. right?
