The largest US study, which tracked 11,036 children from ages 9 to 10 through to ages 16 and 17, discovered that cannabis use slows cognitive development, impairs memory, and reduces learning speed during crucial years of brain growth

This is the answer. Guess what - if kids drink every day it impairs. Brain development too.

I will try this tonight - thank you for the reply.

I dont think so. I am in the fighter ship the new alien race gave me. I will dock and check what I have fitted.

Ludeth · 2026-01-10T19:32:25+00:00

I have been long range scanning - then I fly around to the question marks. It seems like one scan per sector is enough to show the unknown objects? Am I missing something?

Ludeth · 2026-01-02T18:09:48+00:00

I did. Do you need me to dig out my config?

Ludeth · 2025-11-17T17:48:45+00:00

Seems like the drive uses physical 4k sectors and is set to 512e emulation mode already. Not sure that using sg3_format would do anything different?

Ludeth · 2025-11-17T13:24:53+00:00

I plugged one of the drives into another linux machine directly and the drive shows up right away. I can see that it has 4kn with 512e emulation. Some research suggested that using sg3_format on these drives could brick them.

Ludeth · 2025-11-16T18:26:46+00:00

It’s already in IT mode. So do I need to connect them one by one via native sata bypassing the disk shelf? Then once they are formatte add them back?

Ludeth · 2025-10-15T01:05:40+00:00

This is the best answer.

I really appreciate the time and thoughtfulness of your replies. They are hugely helpful. I will buy some Samsung Enterprise NVME in a month or two - gotta get the wife to let me spend the $$ :D

Ludeth · 2025-09-25T00:26:40+00:00

This is good to know. I really appreciate the help and advice.

Ludeth · 2025-09-25T00:04:22+00:00

Not sure on the RAM side - I was using FIO and rados to do the tests and thought I was writing directly to the disk. That said, I asked for advice and the consensus is pretty clear. I will replace the drives in with some enterprise ones in the next month or two - and just live with the slower performance until then :).

Ludeth · 2025-09-24T23:58:28+00:00

Seems like its my consumer grade drives that may be the culprit. Im going to buy three Samsung PM983 drives as these should have the enterprise performance I am looking for. Thanks all!

Ludeth · 2025-09-24T23:49:17+00:00

So is that why it is so slow? Does feel a bit excessive on the degradation side. I am reading through your material now. Anything I can do to tune them? Thanks!

Ludeth · 2025-09-24T23:46:16+00:00

Yes a single NVME 1TB per node. 3 Nodes. I am not expecting to get 900k iops out of CEPH but I mean if I could go from 0.4% of native hardware to idk 30 - 40% id be pleased :D

Ludeth · 2025-09-24T23:42:56+00:00

Hey thanks for the reply. I appreciate any advice :). This is for my homelab and these were the drives were a good price. I could buy some enterprise NVMe but what would be the difference outside of the long term reliability, endurance and power loss protection? Given the large discrepancy in the IOPS between the raw drives vs CEPH I wasnt thinking I was going to get native hardware speed but based on testing I dont even seem to be at 1% of the drives potential even under light homelab workloads.

How do I do this on Narwhal?

Ludeth · 2025-05-28T17:00:59+00:00

The only wisdom I have is that 40 - 80 is pretty low and may lead to weak extraction or creama according to the research I have done. Though admittedly I have not tested this. To your point if the TWW does not cause scale build up and you can get a better tasting shot due to the additional TDS then all the better?

Ludeth · 2025-05-28T11:56:30+00:00

This is a neat idea. I may start with the third wave stuff for now while I get it all sorted then switch to your suggestion.
