It seems I will be joining the league of failing PSU owners.
This is on my second Helios4 from batch3, and it has been crashing lately. Roughly every second day it freezes completely. Oled frozen and nothing new on the serial port.
The system had only 2 drives in it at the time, and one was failing so for a long time I assumed it was the dying drive that was making it crash. The drive has been replaced with a new and working drive, but crashing still occours. Started looking this up and found others with similar symptoms here.
I have tried to limit the CPU speed to 800MHz as mentioned by others. This was yesterday, while no crashes yet we'll see how that goes. But that is not a permanent solution of course.
My concern is that even with only 2 drives, and the system being at roughly half-load doing Glusterfs replication with other helios4 (batch1 with 4 drives. No unintended downtime since initial install) the PSU gets very warm. This is sitting in a cupboard without a lot of air circulation (ambient temp ~28C), but the PSU is uncomfotable to touch for more than 5 seconds. No smell of burning plastics or anything thankfully, but doesn't make me too happy. As mentioned this is with only 2 drives, and the CPU throttled to 800MHz.
The second helios4 is not physically reachable at the moment, so I cannot confirm if this is the same situation.
Also these are both in use 24/7 so testing is possible but limitied.
So it seems that I need to get a new PSU asap. Any recommendations in NL / EU?
