  • What do people use for a shelf-stable backup

    Jump

  • If you need something which can withstand some bitrot on single drive, just use par2. As long is filesystem is readable, you can recover files even if bit of data get corrupted

  • [SOLVED] I've set up docker services behind nginx proxy manager so they're accessible with https, but the http services are still open. How do I close them?

    Jump

  • It means you published 8080. Just stop doing it. nginx can reach that container via internal network (assuming they are on same network). Publishing docker-compose would help.

  • What do people use for a shelf-stable backup

    Jump

  • Just a hdd in usb caddy? IMHO good enough for 4 tier backup.

  • What is everyone using as a HTPC?

    Jump

  • just a normal PC? Streaming should work in a browser.

  • What do you use for notes?

    Jump

  • Just a folder + syncthing. no extra infra is necessary + easy to backup.

  • What access points do you use?

    Jump

  • Get yourself some old cisco 3600 re-flash it with standalone firmware and get enterprise class WAP for cheap.

  • Looking for 1 or multiple HBAs to use with a chassis.

    Jump

  • yes, is what i get reading about that server backplane. NVME part will need another "controller"

  • Looking for 1 or multiple HBAs to use with a chassis.

    Jump

  • what is wrong with old good LSA 2008 based HBAs with SAS-to-Oculink cable? and for NVMe part, adapter is just port format converter, pick any.

  • Simpler alternative to prometheus-alertmanager and/or graphana?

    Jump

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

  • Looking for UPS suggestion

    Jump

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

  • Steps to repurpose old laptop as home server with Debian

    Jump

  • 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.

  • Is it a good idea to purchase refurbished HDDs off Amazon ?

    Jump

  • 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.

  • internal certificate distribution?

    Jump

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

  • Steps to repurpose old laptop as home server with Debian

    Jump

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

  • Anyone running ZFS?

    Jump

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

  • How do you use only ipv6 server?

    Jump

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

  • Do you selfhost your own blog/website?

    Jump

  • 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.

  • Anyone running ZFS?

    Jump

  • 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.

  • What are good harddrives to use with servers

    Jump

  • 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.
