According to this, that is about as hot as the temperatures that existed during the Hadron epoch, or the time period when the universe was between 20 microseconds and 1 second old.
In physical cosmology, the hadron epoch started 20 microseconds after the Big Bang.[1] The temperature of the universe had fallen sufficiently to allow the quarks from the preceding quark epoch to bind together into hadrons. Initially, the temperature was high enough to allow the formation of hadron/anti-hadron pairs, which kept matter and anti-matter in thermal equilibrium. Following the annihilation of matter and antimatter, a nano-asymmetry of matter remains to the present day. Most of the hadrons and anti-hadrons were eliminated in annihilation reactions, leaving a small residue of hadrons. Upon elimination of anti-hadrons, the Universe was dominated by photons, neutrinos and electron-positron pairs.
I don’t want to start making assertions without knowing the specific manufacturer and model of the drive involved, but given that hard drives generally rely upon the existence of electrons to function, which don’t exist at that temperature, one might want to keep an eye out for any other potential signs of trouble showing up, like slower access times or unusual noises.
Somewhere between “melting point of steel” and “core of the sun”. Granted this is a very wide window but your average disk temp is orders of magnitude higher.
I haven’t heard that one before. I don’t have an answer for you but I have some questions. Is there any drive access when it’s doing that? Are you sure it’s all the drives making that noise not just one? Are they all doing that shudder at the same time? Is there any firmware updates available for the new drives? Is there a firmware update available for the controller? did you run smart tests on the drives?
Hi thanks for the reply, doing a extended smart test in TrueNAS now for all the hr disks.
The shudder is coming from all the Seagate drivers instantaneously as if they are cycling or something. Going to check if the noise stops once the system goes ideal after the smart test.
Any chance you can point me to how I could check regarding a firmware upgrade, I assume I would need to pull each drive and upgrade, or could I do this within TrueNAS.
Can’t say I have ever heard that before. Sounds scratchy, is that coming from the drives or something else? The shuddering is normalish but it sounds a bit off. I would do a long smart test to get a better answer if you are unsure. Ideally you should stress test all new drives.
Specially if you are considering leaving it as storage only, I’d say it’s totally worth it sticking to CORE.
It’s stable, tried and tested. And it works. Even if fancy new features like RAIDZ Expansion won’t make it to the GUI, it’ll probably work just fine from CLI.
I have a CORE box as my NAS / Home Server with many Jails running my stuff in it and I don’t plan to switch from that anytime soon. Maybe if my services stop supporting FreeBSD, then I’d start by migrating them to Docker containers running in a Linux VM, and when all of them are migrated, then I’d consider going the SCALE route.
