I’m just this guy, y’know?

In your interwebs, janitorializing things up and keeping the porns online.

  • Mine would be when I had a 48 bay disk array / JBOD fail on me… badly. After a storm, it killed the larger card that allowed for me to get many of the drives into a PCIe 16x slot, and I was relegated down to only getting ~8 disks per box made from spare hardware. A single box I got 16 going. Add to this mix an SSD for mid-line caching.

    These were all running bcache on top of mdraid… One single mount.

    Yes I understand how obnoxiously stupid it was to run RAID6 on a 48 disk volume. It was almost all just stuff I could re-acquire over time, not irreplaceable things.

    I just HAD to solve this one though.

    In come several spare chassis / mobo etc… get a bunch of drives powered and on /dev/ , move to the next.

    A couple spare gigabit switches…

    several gigabit NICs…

    two explicit paths for each machine…

    a bit of iSCSI magic, and one machine now had the physical disks all exposed to it… mdadm --assemble blah blah, bit of UUID chaos…

    It’s surprising that while a bit speed limited (I think I got just around 110MB/sec reads), it was nicely performant for what a huge mess of wires and disks just strewn out around my rack.

    Managed to evacuate all I needed without much issue once I got that going. Now, I try to keep my arrays under 16 drives at a time, or keep a very rigid policy of “I can lose this and don’t care” vs “this box gets RAID10 and/or offsite backups nightly”.

    back up your critical stuff people!


  • Thats a misrepresented story that Rimu was propagating.

    The core issue is that he intentionally went out of the way to try to copy code after directly denying and blocking Mia from submitting PR upstream.

    Why deny the code through GIT/Codeberg, only to copy and paste it (incorrectly as well) and claim it as new features from his team?

    We know the AGPL well enough and don’t care if patches were taken upstream. Lying about it is the issue at core, and slandering folks at the same time.

    These are running ZFS and I have 2 other boxes with similar, most in the 10-12 year range. Spinning drives.

    Good stuff.
