Hi there Asking the questions as a newbie. May be asked a number of times before by many but sorry, it is not clear yet to me.
1. The WAL device is just like journaling device used before bluestore. And CEPH confirms Write to client after writing to it (Before actual write to primary device)? 2. If we have lets say 5 OSD's (4 TB SAS) and 1 200GB SSD. Should we partition SSD in 10 partitions? Shoud/Can we set WAL Partition Size against each OSD as 10GB? Or what min/max we should set for WAL Partition? And can we set remaining 150GB as (30GB * 5) for 5 db partitions for all OSD's? Thanks in advance. Regards. Muhammad Junaid
