Hi,
so I managed to get all up and working and how have DSM 5.2-5967 (DS3615xs) with 3x WD RED 3TB in SHR.
Everything works quite fine except the NAS becomes unavailable (web, share, SSH - nothing can be accessed)
when some "major" disk operations are ongoing. This means copy of hundreds of GBs of data (from previous NAS)
or even when download is around 10MB/s. Also extracting "big" archives (tens of GBs).
Long time short when there is high write rate.
Any advice on what can cause this would be more than helpful.
Already did tests for all 3 drives (SMART, bad sectors) and they are fine.
I can post anything that helps - HW config, logs etc.
Thanks
