We have a freebsd os, and we have multiple volumes attached to it. When we setup our droplet with volumes, we setup automount feature by writing the mount point in /etc/fstab. At this point the volumes are attached in a specific order which causes them to be attached in /dev/da<num in serial> in the particular order. And since auto mount is setup, so at server restart the volumes are correctly mapped to the mount point.
When we resize/rebuild the droplet, then the order in which the volumes were earlier attached is lost, which means the attachment point /dev/da<num> changes for a particular volumes, which in turns mounts volumes in wrong order when the server is started because of automount.
Request you to preserve the order of volume attachment in droplet so the resizing it does not cause an issue with wrong volume being mounted to different mount points.
