We should explain how storagePools and the COW can be enabled in the host filesystem
Maybe something in the advanced guide? Then point to it?

| ## StorageClass with Thin Provisioning | ||
|
|
||
| Thin provisioning creates sparse backing files, meaning disk space is allocated on demand rather than upfront. When using thin provisioning, you must set `formatOptions` to disable block discard, otherwise the filesystem may reclaim space in a way that conflicts with the sparse file. |

I think this is the other way around
If using thinProvision: "false" then there should be no discard?

We're mentioning these but we're not explaining how it works? They need to be configured first

| ## StorageClass with Snapshots Enabled (Copy-on-Write) | ||
|
|
||
| To enable block-level snapshots using copy-on-write (reflink), set `copyOnWrite` to `"true"`. The underlying filesystem must support reflinks (btrfs supports this natively; ext4 requires a reflink-capable filesystem). |

We should probably give examples on how to configure this?
