MGR data on md RAID 1 or not

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi list!

We've got a Ceph cluster where the OS of the Ceph nodes lives on a set of SSD disks in mdadm RAID 1. We were wondering if there are any (performance) benefits of moving the MGR data away from this RAID 1 and onto a dedicated non-RAID SSD partition. The drawback would be reduced protection against OS SSD failure of course, but would it also have any performance benefits?

Best regards,

Roel
