* The recommended filesystem is `ext4`, the recommended persistent storage is [persistent HDD-based disk on GCP](https://cloud.google.com/compute/docs/disks/#pdspecs),
since it is protected from hardware failures via internal replication and it can be [resized on the fly](https://cloud.google.com/compute/docs/disks/add-persistent-disk#resize_pd).
If you plan storing more than 1TB of data on `ext4` parition or plan extending it to more than 16TB,
then the following options are recommended to pass to `mkfs.ext4`:
```
mkfs.ext4 ... -O 64bit,huge_file,extent -T huge
```
