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.
Likely not mentioned since no one yet has had the opportunity to test it.
So how do i have to deploy using bluestore, regarding where i should put block.wal and block.db ?
block.* would be best on your NVRAM device, like this:
ceph-deploy osd create --bluestore c0osd-136:/dev/sda --block-wal /dev/nvme0n1 --block-db /dev/nvme0n1
