Hi!
Question: for what better use SSD? For tiering or for blockdb?
I have this configuration:
sdb - 512GB SSD
sdc - 512GB SSD
sdd - 10T HDD
sdb splitted to sdb1 and sdb2. sdb1 used as blockdb for sdd. In the near future, it is planned to add one more HDD and sdb2 will be used as a blockdb for it.
sdc is used in a pool that is configured as a tiering.
Now I see such statistics:
sdb | busy 0% | read 212252 | write 1540e4 |
sdc | busy 7% | read 46579e3 | write 1181e5 |
sdd | busy 6% | read 18097e3 | write 7219e3 |
I.e. sdb is used only for writing. Maybe in my case it makes sense not to use sdb as blockdb, but add it to tiering?
WBR,
Fyodor.
