mSedek Posted October 15, 2020 Share Posted October 15, 2020 Hello, currently have 3 nvme 512GB working with the array but getting tomorrow 3x 4TB nas drives 5400 RPM WD RED, 1 for data and 2 for parity. The question is, how to add the new drives to the array with the described configuration in such way that I dont lose any data and releasing the nvme drives to also use one of those as cache drive.. Thanks in advance. Quote Link to comment
JorgeB Posted October 15, 2020 Share Posted October 15, 2020 You can the NVMe device as cache, but as single device only. Quote Link to comment

I currently have an nvme array with all my vms and data there, now I bought 3x 4TB HDDS 5400RPM and want to transfer my current setup to the new disks in order to free up the 3x nvme.. so Im asking how to do this without losing my data and VMs Edited October 15, 2020 by mSedek Quote Link to comment

trurl Posted October 16, 2020 Share Posted October 16, 2020 Is there parity in your array? Quote Link to comment
trurl Posted October 16, 2020 Share Posted October 16, 2020 Actually it doesn't matter since it would be too small to help. Just create a new array with the HDDs and use the Unassigned Devices plugin to mount your nvme disks. Then you can copy their data to the array and reuse the nvme disks for cache. 1 Quote Link to comment
