I have an SQL database running on a Kubernetes pod on a Ubuntu server with NVME drives and would like to move it to Truenas scale.
In TrueNAS scale, I installed MySQL, and launched the Docker image using a hard disk and everything appears to work, just slower. So now I would like to move the NVME to see if I can get back my performance loss.
Q1: Is a single NVME with no redundancy supported on Truenas/ZFS?
Q2 : How much slower is qty 3: NVME with Z1 redundancy than qty 1 NVME without redundancy? I understand the loss of redundancy, interested in speed.
Q3: qty 2: Speed compare of qty 2 NVME with mirror vs qty 3 NVME in Z1 configuration?
Q4: Can I mount ext4 in TrueNAS to copy over the data?
Q5: Is an NVME Cache drive useful for NVME disks?
Thank you in advance for your suggestions.
