Hi guys i'm reading different documents about bluestore, and it never recommends to use NVRAM to store the bluefs db, nevertheless the official documentation says that, is better to use the faster device to put the block.db in.
In my cluster i have NVRAM devices of 400GB, SSDs disks for high performance and SATA disks for cold storage. So how do i have to deploy using bluestore, regarding where i should put block.wal and block.db ? Do i have to use the NVRAM just for the block.wal and put the the block.db in the same SATA and SSD disks as the DATA ? or should i have to use NVRAM for both block.wal and block.db ? Any idea if exists some special constraint about putting block.db into NVRAM, even when the backend disk is an SSD ?
