Folks,
we’re building a Ceph cluster based on HDDs with SSDs for WAL/DB files. We have
four nodes with 8TB
disks and two SSDs and four nodes with many small HDDs (1.4-2.7TB) and four
SSDs for the journals.
HDDs are configured as RAID 0 on the controllers with writethrough enabled. I

Folks,
I am running into a very strange issue with a brand new Ceph cluster during
initial testing. Cluster
consists of 12 nodes, 4 of them have SSDs only, the other eight have a mixture
of SSDs and HDDs.
The latter nods are configured so that three or four HDDs use one SSDs for
their blockdb.
