Enabling both cache_mode and SSD Data Tiering in dragonfly

[jahnavilatha589]

Can I enable both cache_mode and SSD Data Tiering..? As cache_mode evict keys if maxmemory is reached.

I enabled both cache_mode and SSD data tiering, but once the max memory limit reached, I encountered the following error:
" tiered_storage.cc:163] Should not reach here"

With cache_mode enabled, it should remove keys from memory, correct?

Shared some info and configuration details below.
