[Navy BlockCache] Is device resize handled without data loss?

[dannycho7]

For Navy BlockCache, I noticed that ItemRecord addresses are aligned by an amount that is dynamically calculated based on the device size, with a minimum alignment of 512 bytes.

Is it possible for a device upsize (e.g. from 1 TiB to 16 TiB) to cause data invalidation due to the alignment of addresses changing?

Yes. And the Device class size is just the amount of space assigned to the cache. So just a config change without physical device change could cause the data to drop.
