Hi everyone, As a newbie, I have some questions about using SSD as the Bluestore journal device.
1. Is there a formula to calculate the optimal size of partitions on the SSD for each OSD, given their capacity and IO performance? Or is there a rule of thumb on this? 2. Is there a formula to find out the max number of OSDs a single SSD can serve for journaling? Or any rule of thumb? 3. What is the procedure to replace an SSD journal device used for DB+WAL in a hot cluster? Thank you all very much!
