Hi guys,
I need an advice about my unRAID setup.
I have currently
Parity: WDC_WD40EFRX-68N32N0_WD-WCC7K0AX8TV6 - 4 TB (sdb)
Disk 1: Samsung_SSD_960_EVO_500GB_S3EUNX0J117017X - 500 GB (nvme0n1)
Disk 2: WDC_WD40EFRX-68N32N0_WD-WCC7K0XNAZ5S - 4 TB (sdc)
The thing about this setup is that I used the 500GB SSD as one of the disks so the parity is now using it.
I saved all the VMs, and Docker images to this drive for better performance (this SSD is m.2 drive which is crazy fast, about 1400 Mb/s).
Then I have unused
250GB SSD (about 500 Mb/s)
3TB general magnetic drive from Western Digital (RED edition), same like other two which I am already using just 3TB instead of 4TB.
So now, I need to use all of them and do it right this time
Permanently remove the 500GB SSD from array as the storage drive and use it as cache drive
Move all data from Disk 1 (500GB SSD) to new cache drive (500GB SSD) = same drive
Add new 250GB SSD
Set SSD Pool (I am not sure how will the two different sizes and speeds of this drives play together)
I still want to use primarily m.2 500GB SSD for its speed
but for network transfer, 250GB SSD is still fine (I will not exceed 110 Mb/s network transfer)
does it even make sense to use this drives in the pool?
Add new 3TB drive
My main concern is that I need to transfer all VMs and Docker images from current Disk 1 to new parity which is the same drive.
Any advice how to proceed?
Thanks!
