    Two (plus) comments:
    1. I doubt that any type of production deployment will seriously consider converting live data from RAID1 into RAID-N.
    1a. ... As such, I doubt that btrfs mixed RAID level will...

    Again, your point may be valid for home desktop w/ 4 drives or a low-end server with 8 drives.
    Building a 100 or 200TB RAID10 setup is simply not practical, let alone the fact that RAID10 is less...

    Sure.
    Let see you build a 200TB RAID 10 setup, and explain to the people who are paying for it, that you are spending twice as much on hardware (actually, more than twice, depending on the actual...

    Interesting. Thanks.
    I would imagine that the performance hit in large clusters (E.g. 16+ cores) will be unusable.
    Than again, assuming that the main use case for this CPU is light/mid-end DPI with...

    Care to share the combined RAID space you have?

    1. RAID1 is *not* faster. In many loads (E.g. large sequential read/write) large RAID5 (and 6) array will run circles around RAID1.
    E.g. On a server w/ 8 x 4TB 7200RPM drives I have two Linux MD...

    Most likely the "shallow" side of DPI (E.g. state-full smart routing, etc).
    With 100 cores, and 200Gbps, each ARM core has to handle 2Gbps of raw traffic, even if I somehow assume that the H/W load...

    Weird. I have software RAID on 10+ servers/workstations (some with 8+ drives RAID6 setups) with at least half of them being used for internal kernel development testing, which usually ends with a...

    systemd was designed as "standard base system" from more-or-less day one.

    From the initial systemd announcement [1]:

    It was not my intention to throw mud at Gentoo.
    It was my intention to suggest that if you expect systemd and PA to work out of the box, Gentoo might not be the ideal solution.

  15. Gentoo is the wrong tool to test either PA or...

    Gentoo is the wrong tool to test either PA or systemd, as Gentoo lacks, in both cases, a dedicated integration team.
    Far worse, many Gentoo users prefer the "clean" approach defaulting to sysv and...

    Forgive me for asking a rather dumb question.
    I'm using PA on more than 20 netbooks, laptops, desktop, and workstations I manage (>40 if you also count VMs). All running Fedora or CentOS 7.

    First, as a general comment, when one tries to throw insults at at another, one should use semi-proper spelling and grammar. Throwing badly phrased insults simply makes you look like a simpleton,...

    Read my lips, SLOWLY, CentOS uses RHEL SRPMS (sources) and recompiles them while trying to maintain binary compatibility. This means, my dear troll, that if RedHat uses GNOME 3, systemd or any other...

    If someone has physical access to your machine, he can install a a cheap *physical* USB key logger on between your keyboard and your computer and he owns your ass.

    Mind you, I do agree that a...

    Quoting myself:



    Am I wrong?
    Sure, PyPy *should* (or may) generate C code that uses safe string types, some-what better house-keeping, but neither one gives an concrete advantage over modern...
