No, if you used cache tiering, It is no need to use ssd journal again. From: Florent MONTHEL Date: 2015-01-17 23:43 To: ceph-users Subject: [ceph-users] Cache pool tiering & SSD journal Hi list,
With cache pool tiering (in write back mode) enhancement, should I keep to use SSD journal on SSD ? Can we have 1 big SSD pool for caching for all low cost storage pools ? Thanks Florent Monthel
