Hi, I'm running Unraid 6.12.3 and I'm having trouble with my Mover speed. I recently upgraded my array from 2 HDD's (1 parity, 1 storage) to 4 HDD's (1 parity, 3 storage). All those drives are Seagate IronWolf 4TB drives.
For my cache I upgraded from one Samsung SSD 980 500MB drive to 2 Samsung SSD 980 1TB drives (mirrored).
Since this upgrade my Mover speed dramatically slowed down when writing to the array. The speeds I used to get got close to the maximum speeds of the HDD's which is 180MB/s but now I get around 60MB/s.
I already scouted the internet and this forum for answers but can't really figure out what caused this drop...
Is this maybe a normal cause of having a mirrored cache system? Or is there something wrong?
Thanks in advance for your time!
