As owner of dark green car I can say, do not buy this color, it is bloody stealth car. No one see you on the road. Have to drive with light on all the time. I guess only grey is worse that it.

ICINGA/NAGIOS? you can even feed data already collected by Prometheus to it if you want.

Ahh age of switching PSUs and led lights. 20 years ago you will notice it in an instant.

A4-6210 with build in GPU has TDP of 15W. There is no point to optimize anything it is seeping power already. may be try to use tlp to limit max charge level of the battery ( i’m not sure is you laptop is supported). You can play with governors too, but I personaly will not bother. You obviously need multiuser.target but not GUI.

With raid 10 - i would not risk it . With RAID6 ( obviously not on BTRFS) it is fair game if you have solid return policy for drives which are DOA. Go for SAS drives, they are cheaper (but generally hotter and nosier). And look for old-new-stock on specialized sites, no one in enterprise needs say 8tb drives, so they selling them cheap at times.

Get drive, connect , run long smart self-test ( for 18tb it is probably take a day). If it passed you are reasonably sure that it will not die soon. And keep running these test regularly, as soon as they start failing, replace.

Bump root cert to 10 years and use intermediate with shorter lifetime. root cert should be stored and processed off net.

It would be useful to know laptop spec. In general, do not bother power consumption should be lower enough as it is.

to stop guessing what HDD to replace when one failed. VM can’t see actual HDDs as SMART is not getting forwarded.

I guess HE is still providing free IPv6 via IPv4 tunnels.

Biggest problem will be BW and latency to your lab from the Internet. I would use dedicated hardware and subnet for it. Security wise, if you can make your site 100% static it will help a lot with security. I’m personally set on AWS S3 + CloudFlare combo with static site generator running in my lab. Yes it is not really “self hosted” but worries free solution for me.

both works. Just do not forgot to assign fake serial numbers if you are passing disks. IMHO passing disk will be more performant, or may be just pass HBA controller if other disks are on different controller.

Just imaging how much pollution this bikes on road generates, it would be way better if they continue driving.

ZFS or BTRF mirror will know which side is at fault due to checksums. I’m more concern about simultaneous falures of two disks. Rebuilding of a RAID puts lots of pressure on remaining disks, so probability that remaining one dies too is much higher. with RAID6 3 disks need to die to lost date, which is less likely but not impossible.

I would not trust these kind of dives in the mirror. IMHO RAID6 is the only way.

LE only certify your domain name, you may want to put more (like company name) to cert and it is where classic certs providers come to help.

ZFS ZIL will not help in this case.

Usually it can be solved by talking to hotel stuff. you are paying for that service and can expect it be suitable for any legal use.

trouts are for Englishman. Aussie prefer whales.

Nope. You do not need physical access for it, just root access. and you HW is compromised with only means to recover it is SPI flashing of CPU.

They are definitely not giving a f^&* over radiation belts. Polaris dawn and now this one. But we need know orbit details to be sure.
