could you run something like sudo lsblk -o+MODEL and note down the model for the drives? i kind of suspect that the HBA you are using is still doing some abstraction and is not in IT mode. the duplication could come from connecting two SAS cables to the same backplane, thus creating a sort of double image of the enclosure. this is usually handled and hidden by the HBA though if it is configured correctly.

pls also check that you are in fact using the correct ports on the enclosure. if you are not building a SAN only the "A" ports are supposed to be used and the "B" ports should be unused/free.

just a bunch of individuals drives

that is literally what JBOD means so congratulations you already have one. a classical RAID would show up as a single drive.

Initiator-target (IT) mode enables creating a JBOD with zfs vdevs on it. You can have the zfs vdevs in raidz configuration (which would give you the same drive redundancy as a hardware raid, with raidz1 performing similar to RAID5)

zfs is commonly used with a JBOD configuration on a raid controller but you can also use any other kind of controller as long as the individual drives can be written to. examples for this would be NVMe drives directly attached to the PCIe bus or normal SATA controllers. This is more a performance optimization than an issue with compatibility.

In the Netherlands you can legally buy grow kits for magic mushrooms. They are fairly easy to use, mostly just weekly/daily checks to keep moisture at the right level and making sure to harvest at the right times (you usually get multiple harvests from just one kit).

Personally i think doing a shroom trip alone is too dangerous … so maybe find a group first?

I think what he was trying to point out is that you should not expect a direct visible effect of the dwindling funds on the events on the battlefield. It will be much more indirect and delayed by month, maybe years.

”nitrogen-rich fossil fuels that feed our culture“ wow this article is really badly researched. the problem is of course real and has been described very well by William Crookes in 1898. The answer back then was the development of the Haber-Bosch process. The input was originally hydrogen from coal not natural gas which shows that the process is a bit more adaptable than this article makes us believe.

hydrogen can be obtained from many sources (including as a pure substance from wells as white hydrogen) and the reason why we use natural gas today is because it is much cheaper than the alternatives, not because other source materials would not scale as well.

how we will be creating inorganic nitrogen fertilizer in the future is a question to be solved but it is not an insurmountable problem – more like an upcoming shift in our economic practice because we will have to switch to more expensive sources.

maybe they were going for the classic meme? https://www.youtube.com/watch?v=3m5qxZm_JqM

the infuriating thing is that according to the books he is a pretty unique mix of ... checking ... ”the only child in a family co-op of five fathers and three mothers“

they could have done almost anything with the character in terms of appearance and chose this sigh

I mean sure but on the other hand the Ukrainians have modern radar so this is a bit surprising still.

I think it went a bit further than just selecting the right paint.

I remember there was a program to enhance the stealth for relatively low flying surveillance aircraft (still mostly propeller aircraft at that time) and one of the most effective measures was painting the underside of the plane White and then illuminating it on purpose with a light that was matched to the sky. The light was usually bluish to match the sky. https://en.wikipedia.org/wiki/Yehudi_lights

The reason why this was not simply done at night was of course that the surveillance equipment needed some light to work :)
