TerraMaster Forum

Initially looked like a corrupt disk issue. Unit shut down during night. No apparent errors. On eventual reboot, works a short while then shut down again. Further reboot, completed a full sync ( 2 6 GB drives in Traid) Ran a couple more days then shut down again in early morning. System tried to restart (as if after power restoration as is set) but failed similar to below

Since then I have reset CMOS (or whatever you want to call it these days) by removing battery and short +/-ve as suggeted. Cleaned all connectors and power switch, removed additional memory.

With no drives installed, as soon as insert power plug:
Power light, 2 red HDD lights, wait 5 seconds, BEEP, Lights flash, all lights off.
This is repeatable.
If I connect LAN cable I might see LAN led flash briefly once or twice before other leds and BEEP.
If I leave box alone with power connected it will (randomly) repeat the process. The randomness can vary from almost immediately to 30+ seconds.

When the unit shuts down, the power button has no effect to restore power (long or short pushes). This unit has a reset button but that also appears to have no effect.

With drive re-inserted there is a momentary power up and then it shuts down as (if) power failure.

Boot never seems to get far enough to access BIOS.

Any clues?

[PS - This unit was running TOS6Beta (latest version as of Feb2/3) But that does not seem relevant.]

ps. Solid green on power supply and steady 12.13volts

Remove all the hard drives from the device, connect it to the monitor, restart it until it shuts down automatically, and finally take a photo of the content on the monitor and provide it to us.

Hard drives were already removed .... self preservation kicks in
I would send you a photo as described but it would only be of a blank monitor. Too be certain I switched to a (known) working power supply and monitor. All that appears on the screen (very briefly) is the TerraMaster splash screen. It goes past so quickly to "power off" state that I cannot get into BIOS.
Just to re-confirm: after the splash sscreen, the monitor is blank.

PROGRESS!

1. Replaced CMOS Battery = no improvement, except perhaps (hard to tell) variations in 'beep', sometimes no beep.

2. Removed battery and tried cmos reset again but without shorting +/- terminals. Left for 30+ minutes then replaced = as above

3. As 2, plus removed initboot usb, Replaced battery BUT NOT initboot. Machine did not automatically restart!. Power-on via switch machine booted to CMOS!

Showing CMOS Checksum error ?maybe normal? "Core 5.12 date 12/17/2018"
Reset obvious bios parameters (date for one) but not certain of "required defaults".

4. Shutdown via switch. Restart via switch - boots back into CMOS, settings preserved. Ethernet plugged in and system found by TNAS-PC (uninit). Shutdown.

5. Added 1 drive of raid 1. Startup. BOOTS to TOS login OK [Raid is 'degraded, naturally']

6. Added 2nd raid hdd. Restart. Raid sync in progress.

So far so good. However I have been here before and it didn't last. Any suggestion as to what steps next (if only to preserve my sanity).

Update bios?
Replace initboot usb?

Thanks.

BUST AGAIN

Getting boring!. Raid rebuilt and synced. ran overnight without case to be in a position to change anything. Couple of reboot to verify functionality and a shutdown. Returned to case at 15:30 local and at 15:45 it crashed again. Does not appear to be system/cpu/hdd heat related as I was tracking these numbers which at 15:34 were 29/31/38 resp with fan @ 1123rpm.

You can refer to this link to update the bios viewtopic.php?f=82&t=4238 , but it is not ruled out that there may be problems with the startup USB drive. You can remake it viewtopic.php?f=76&t=3684 or contact after-sales for replacement

But would an issue with the USB drive manifest itself after several hours of operation?

OK (maybe)

Re Bios:
The linked page does not reference my model (F2-221) as it appears to be for later models. Mine shows
J3355_5.12_v4.9.19 AND a bios date of 12/17/2018

Re Initboot:
I have looked at the pages requiring some form of linux os to prepare. This (as has been pointed out to you by others) seems unduly complicated. Also I cannot see that it mentions the optimal size of usb drive that is needed.. In addition I note (in the suppoort downloads a couple of versions of "common_bootloader" images. Do these serve the same purpose and how are they loaded? Can they be loaded via an available windows machine without VM? Or, as a last resort, some form of CD bootable instance of linux?

ps. the instruction pages do not help when they present code/screenshots with typos ('chomod' for one - which was the easy one to spot.)

Thank you
