Hello all,
I am very new to unRAID but not necessarily new to computers and servers. I am in the process of converting my buddy's Ubuntu Server over to unRAID. The server boots, created the array, tried installing/using dockers and plugins, everything runs great. Love unRAID. I have yet to purchase a licence (19 days to go) because I am having a hell of a time with this thing and hard power downs. Literally powers off like it was unplugged, no errors, nothing on the terminal (I recorded a video), Fix Common Problems Troubleshooting mode doesn't record errors, even tried a syslog tail. Nothing. Thus far, I've found this ONLY happens when copying large files to the server, in this case, large media files. The server can run full parity checks/corrections with no problem and will run for days if left alone. All things point to hardware but I wanted some opinions or other ideas before digging in to what's left (ie: MoBo and CPU). Here is the server and my process thus far:
Components:
- Motherboard: Supermicro C7SIM-Q
- CPU: Intel Core i5 CPU 750 @ 2.67GHz
- RAM: 4x G.Skill RipjawsX F3-12800CL9-4GBXL (16GB total)
- SATA HBA: * Supermicro AOC-SAS2LP-MV8 * (I understand the implications of this but hear me out)
- Parity Drive: 1x WD Green 3TB
- Array HDDs: 1x WD Red 3TB, 3x WD Green 2TB
- SSDs: 1x ADATA SP550 120GB (cache)
- Flash: Sandisk Cruzer Fit 16GB (boot)
- Video card: NVIDIA GeForce 7900 GT/GTO
- PSU: Seasonic X Series fanless
Secondary Components tried:
- RAM 2: 2x Crucial 8GB DDR3L-1600 UDIMM (CT102464BD160B)
- PSU 2: Antec EA-750 750w
Combinations of hardware tested (no specific order and multiple combinations):
- No video card
- 8GB RAM
- No SATA HBA card (SDD/HDDs direct to MoBo)
- No cache drive
- Updated BIOS to newest
- Updated SATA HBA firmware to newest
- Different PSU (see PSU 2)
- Disconnect cache drive entirely
- Flash drive in new port
- Different RAM (see RAM 2)
- New array with RED drive as parity
Tests and different settings:
- Memtest86 for 6+ passes (24hrs), no errors on RAM 1
- Virtualization enabled/disabled
- C states enabled/disabled
- BIOS to defaults
This has been an ongoing process for over a week. Diags attached. Appreciate ANY ideas/thoughts/comments/snide remarks.
