Sysadmin Mega Thread

It’ll be a software repository and could host a variety of different binaries. Basically, it would be nice to do a get request to a URL like

https://software.example.local/security/antivirus.deb

and it will download it.

I could do it with apache and a .htaccess file, but I’d like to see what other options there are.

Yeah, I heard that there’s something coming down the pipeline, so I’m just gonna hold off until I see what’s coming.

I personally use proget for this, specifically for chocolatey packages. It only runs in docker though, and is not FOSS. It does have have users, groups and permissions, although you have to pay to get per repository permissions as the free version just has global permissions.

You also could look at nexus oss.

I’m genuinely surprised ZFS fared so well.

I thought it was going to be way slower, without a SLOG

ZFS 0.7.5

The throughput of a bunch of disks in aggregate is pretty good. SLOG helps reduce latency for sync writes, if you have a very low latency SLOG device and it’s not being overworked. Most of the tests shown are async workloads, and latency isn’t even measured.

Some SSDs for it arrive today. :slight_smile:

An IR card I expect to be able to flash to IT mode comes in a week to replace the full RAID abomination this came with :shushing_face:

18.04 uses 0.7.5 so that’s probably why. 20.04 has 0.8.3

fedora pulls directly from the zfsonlinux repo.

so…
at least I got that going for me.

Let us know how they perform

Waiting for an LSI3008 based raid mezzanine card to come for real testing. I should be able to flash that with IT firmware…

The hardware raid controller is not impressing me the least bit. A raid6 of 6 drives was pathetic:

D512B-2U ➜  ~ sudo dd if=/dev/zero of=/dev/mfid0p3 bs=32m status=progress
  167772160 bytes (168 MB, 160 MiB) transferred 23.668s, 7089 kB/s

Compared to creating a jbod of each disk and creating a raidz2 pool with sync=always:

D512B-2U ➜  ~ sudo dd if=/dev/zero of=/p0/f bs=32m status=progress
  8254390272 bytes (8254 MB, 7872 MiB) transferred 27.099s, 305 MB/s

The JBOD mode doesn’t even expose TRIM. :expressionless:

I should go through and update all the firmware at least, but lol

D512B-2U ➜  ~ sudo mfiutil show adapter
mfi0 Adapter:
    Product Name: LSI MegaRAID SAS PCI Express ROMB
   Serial Number:
        Firmware: 24.7.0-0026
     RAID Levels: JBOD, RAID0, RAID1, RAID5, RAID6, RAID10, RAID50
  Battery Backup: present
           NVRAM: 32K
  Onboard Memory: 1024M
  Minimum Stripe: 64K
  Maximum Stripe: 1M

And yes I am planning to use fio for the real testing. dd is not a benchmark :wink:
