TL;DR Ver
Recently re-did my RAIDz2 array (added another drive), but when transferring data back (simple drag-and-drop) the speed starts out very fast, then crashes down to nothing for a few sec, then speeds up again, then crashes for a bit. During long transfers the crash will cause a time out and error the transfer out.
Long Version:
My FreeNAS box had been off since last Nov when I had 2 drives fail. I recently had enough money to replace the bad drives, and the process went smoothly. Re-Silvered the drive, all was well. Then I got a fun side project which gave me some fun money for upgrades. So I purchased a new motherboard that can hold an 8th HDD, and a drive to fill the slot.
I backed up all the data across several HDDs I am borrowing from friends for the week, destroyed the RAIDz2 setup, set up a new RAIDz2, set permissions, etc. All appeared to go well.
Went to start throwing data back on the fresh RAIDz2 and the first chunk of data (~2.5TB) went well, but then it started hanging. I started getting ~30sec hangs where data was not transmitting, followed by ~5-15 sec of full 113MB/s data flow. On occasion the pauses were long enough where it would error out the transfer and I would have to try again, but when moving TBs of data it becomes painfully slow.
My first thought was that there was perhaps something wrong with the temp drives I am borrowing, but I have tested data transfers to my wife's PC, and those go fine, and these pauses are happening with any connection into the FreeNAS box. So hopefully this means my data is safe :D *phew*
My next thought was that perhaps it was a system resource issue on the server. Checking CPU history (AMD A10 5800), but usage is pretty low, averaging ~10-25% load. RAM usage is pretty well maxed out (20GB, 2x8GB, 2x2GB), and I think I am going to give up 2 8GB sticks from my desktop that I am not really using to bump the server up to 32GB (4x8GB).
The obvious suspicion is that there is an issue either with the motherboard or HDD that I added last, but no errors are poping up in the UI of FreeNAS.
Any thoughts/ideas to help troubleshoot or to get the system to find/surface an existing error that may be causing this weird behavior?
System Info:
FreeNAS 9.10
CPU: AMD A10 5800
Mobo: ASRock FM2A88M Pro3+ FM2+
RAM: 20GB DDR3 2x2GB, 2x8GB
Drives: 5 Seagate consumer drives, 3 HGST server/SATA drives, all 7200 3TB drives
RAID: RAIDz2, 3TBx8 drives ~15GB usable space
Thanks!
