Documenting PSU Explosion #19

Closed ohnoesIaccidentallyAPSU closed 2 years ago

ohnoesIaccidentallyAPSU commented 2 years ago

Running gentoo on 1.10 kernel my PSU exploded on a Proliant DL380 G7 while mounting the hpsahba drives during the initramfs! Thankfully, nothing was harmed and that was a new server, with no data on it. All is well

Two things:

  1. Be very careful when using this! I am not blaming this project for what happened. But, it happened nonetheless
  2. IF YOU ARE USING OLD HARDWARE FOR THE LOVE OF GOD CHANGE OUT THE OLD PSU WITH SOMETHING NEW AND HIGH QUALITY. These servers are very cheap, don't skimp out on important stuff

It is very unlikely that hpsahba or kernel patches caused this.

Spinning disks drain a lot of current during spindle spin up. Most probably, your PSU failed because of a combination of 1) PSU wear out and 2) current spike during disk startup.

Yes, I doubt it was caused directly by the program. Rather, a combination of factors. Merely a PSA... Check that your PSU is robust before using this 🤔 especially if you are using lots of drives
