System storage consists of two type of files: (a) system files that are necessary for operating the core system of the device and (b) temporary system files: system settings, backups, logs, caches and other files. My Mid 2012 MacBook Pro 13' says I suddenly ran out of Storage space. My Mac barely has any data and my upgrade to Sierra was a clean install. Nothing was ported from previous backups. If you see the image below, the 'System' section in the left column says that it is consuming 466.82 GB.
After upgrading to macOS 10.13 High Sierra, you may notice that there is a category named 'Other Volumes in Container' in Storage and 'Other Volume' in Disk Utility on your Mac. And the problem is that when you are getting the warning 'your disk is almost full' from the Mac, other volumes in container are taking ten or even hundred gigabytes of your Mac storage space. Some users also noticed that the size of other volumes in container keeps growing on their Macs. And the worse part is that you don't even know what other volumes in container mean, let alone how to delete other volumes in container.
So in this post, we are going to explain to you what other volumes in container are on Mac and how to get rid of other volumes to reclaim your Mac storage.

1. What Are Other Volumes in Container?
In APFS, the new file system that Apple introduced to macOS High Sierra and later, a container is similar to a partition in other file systems. A physical disk could have multiple containers and a container includes multiple virtual volumes, which all share the storage space of the container. For example, a standard macOS startup APFS container includes volumes as follow:
Macintosh HD: the volume with macOS software system installed, which usually shown in Disk Utility as Macintosh HD.
Preboot: the volume that manages boot, which is created during macOS High Sierra update to support booting to Macintosh HD. It is usually hidden.
Recovery: the volume that contains recovery system of your Mac, which you can boot into by holding CMD + R during startup.
VM (Virtual Machine): the volume that supplements your RAM to store files like sleepimage, swapfile, which is too large for RAM to run. So VM volume usually takes up most of the storage space.
Other volumes in container mean the last three volumes, Preboot, Recovery, VM in APFS container. The other volumes cannot be removed because they are needed for macOS to function properly.
Although we know what other volumes in container are, it doesn't mean that we can easily get rid of other volumes in container. In fact, we cannot completely delete other volumes in container on Mac because they are important for the system to run. However, there are ways to stop other volumes from increasing or reduce the space that other volumes using.
2. Thoroughly Clear Your Mac to Release Memeory Space
To get your storage from other volumes, you can use FonePaw MacMaster. FonePaw MacMaster is an application that can clear caches, logs, iOS backups, iOS update files, mail attachments, apps, and app data, duplicate photos and files, large and old files, browsing history, etc. on Mac to get more free space.

Just let the application scan through your Mac and find out files or application that are taking up most of your space. Then you just have to click Clean to get rid of them.

It sounds irrelevant but some users found other volumes stop growing with the following hardware.
