How to test disk performance.

[ozgurerdogan]

I know there are many dd or hdparm tests around. But is there any better or prefeable test for proxmox to test disk performance overall? Can you please write it?

Hi!
This depends on which storage is used in your cluster.
For CEHP-storage: rados bench
Better for other: Bonnie++
