I have inherited a cluster where about 30% of the osds in a pool are 7200 SAS. The other 70% are 7200 SATA. Should I look into creating 2 pools or will this likely not be a huge deal?
I would benchmark them both, and see how similar they are. On Wed, Oct 16, 2019 at 1:38 PM Frank R <frankaritchie@gmail.com> wrote:

I have clusters mixing with no problems. At one point we bought a SAS model, when we don’t have a local exact spare we replace dead ones with SATA. Some HBAs or backplanes though might not support mixing. Unlike crappy HBA RoC vols, Ceph doesn’t care.
