Hi all, We know FileJournal plays a important role in FileStore backend, it can hugely reduce write latency and improve small write operations. But in practice, there exists exceptions such as we already use FlashCache or cachepool(although it's not ready). If cachepool enabled, we may use use journal in cache_pool but may not like to use journal in base_pool. The main reason why drop journal in base_pool is that journal take over a single physical device and waste too much in base_pool. Like above, if I enable FlashCache or other cache, I'd not like to enable journal in OSD layer. So is it necessary to disable journal in special(not really special) case?
