Sysadmin Mega Thread

It’s for their built in CI/CD pipeline. A runner can be configured to use docker, so what I am assuming is they could theoretically also use podman.

should be… i did notice the restart option names changed coming from docker to podman, but otherwise I just replaced docker with podman in the command

As long as you mount /var/run/docker.sock, probably.


There’s also this guide I found from a quick google:

Putting them threads to work :mechanical_arm:

Server is doing F@H in a virtual machine allocated 8 cores, and the rest is doing a H264 encode.

That heatsink is doing a good job keeping this beast cool. The fans are currently at 38%.

Question for those familiar with flash memory. I cooked the SLOG and cache SSDs on my zpool this week. They’re down to 50MB/s sequential write. Can someone recommend a high-endurance replacement either 240 or 480GB? Ideally, I’d like to see somewhere around 1GB/s sequential. I also have no idea what I’m willing to pay since I don’t really know exactly what I’m getting myself into… I know this isn’t really the ideal amount of info, the issue is that I’m pretty out of the game lately.

what were the old slog/cache devices?

how old were they?

I use an optane 905p… its been a few months since I last checked the smartmon data… but its over a year old now…

I second optane for endurance and speed

SATA, SAS, M.2, or addin card?

970 evos 250GB each

2ish years?

either m.2 or PCIe. Preferably PCIe.

Almost 17000 hours
available spare 100%
1.5 billion write commands

Hmmm, that’s impressive. But damn, I wasn’t hoping to spend that much…

I guess high-wear-level flash is expensive though. :confused:

I saw a few of the 100gb dc4801x u.2s around…
(I believe theres a m.2 version of it also)
Under 300

But rated for higher endurance

I’ve been told you don’t want the M.2 Optane drives. They overheat too easily especially under heavy write load.

Can anyone recommend FOSS software for Linux that works as a software repository?

I was considering using apache with .htaccess, but I think there’s a better way.

It would be nice if it had built in tools for client account management. That way different clients could have different accounts / keys.

Ultimately, I’d like to put software on these repositories and have servers fetch software from them using automation.

I hope that description is helpful.

3.5 hours later, demo environment has been rebuilt.

Things that went wrong:

  • vault wouldn’t unseal from snapshot. Had to rebuild multiple times.
  • certain secrets didn’t carry over
  • prometheus is a bitch
  • zookeeper is terribly designed.
  • kafka is the slowest program I’ve ever experienced.

Deploying a new environment usually takes 1.5 hours.

Optane?

Edit: beaten by a lot. But yeah optane spec/etc screams “slog device” to me.

Is this like linux packages, deb, rpms, etc? Random stuff that is just downloaded and run manually in a script? Windows software?

In Linux/Raspian is there anyway to encrypt a mounted external HDD that already has data on it? All I’m finding is that I have to nuke whats already on the drive, then encrypt and put data back on it.

That would be correct AFAIK.
