  • HFS+ să nu fie o idee foarte bună
  • două ramuri ale ZFS-ului
  • cea oficială, dezvoltată de Oracle
  • și cea deschisă, dezvoltată de OpenZFS
  • Oracle a continuat să lucreze la ZFS, însă noile funcții sunt disponibile doar pentru Solaris
  • snapshoturilor native
  • și dacă nu ați avut probleme până acum cu el, nu înseamnă că în viitor veți fi scutit
  • securitatea datelor, continuați să citiți.
  • Un inconvenient ar fi faptul că încă nu poate fi accesibil pe Windows
  • Windows vor trebui să folosească un Linux/BSD într-o mașină virtuală
  • avem nevoie de trei lucruri
  • cred că Time Machine din OS X a fost o facilitate introdusă cu gândul la ZFS
  • ZEVO, o inițiativă privată
  • Dacă țineți la datele voastre
  • MacZFS
  • Proiectul oferă ZFS v28, compatibilă cu ultima variantă liberă oferită de Oracle
  • fiți mereu cu un ochi pe versiunea folosită
  • versiunea sistemului de fișiere și nu a sculelor software folosite pentru a-l administra
  • dezvoltarea mac-zfs va fi integrată de acum cu OpenZFS
  • ignorăm MacZFS și să trecem direct la OpenZFS
  • Într-un episod viitor, voi detalia cum putem să și folosim facilitățile ZFS-ului
  • OpenZFS Înainte să continuăm, dacă aveți instalat MacZFS, va trebui să scăpăm de el.
  • ușor accesibil
  • Xcode
  • Xcode Command Line Tools
  • Homebrew
  • Probabil veți dori ca sistemul să încarce de fiecare dată kext-urile de fiecare dată după reboot. La mine acest lucru a dus la un kernel panic
  • probabil din cauză că folosesc hacktintosh
  • Ca un rezumat, de fiecare dată când veți dori să aduceți la zi uneltele OpenZFS de pe github

      2013-09-28 in IRC for OpenZFS: "… not very confortable using a 'well-developed alpha' for storing my data …" "… alpha & beta are technical terms …" "… https://github.com/zfs-osx describes what's there as alpha, experimental …" "… since february, lol …" "… I have not tested ZFS-OSX enough to say whether it's alpha or beta. Moreover it's for the developers to decide. … alpha is a suitably cautious description whilst testing is not as widespread as we'd like …" "… .zfs directories are not present yet, it is technically alpha in that sense … connotation not denotation, and the connotation of alpha for those not very familiar with the technical definitions is very negative. …" "… better to use neither the term alpha nor the term beta than to use the term alpha, alpha is simply terrible diction in this context" "it's true that 'alpha' and 'data storage' don't go to well together, but better to be safe than sorry …" "… brand perception of the term "alpha" by the public is "garbage' …" "… OK so maybe avoid both phrases (mention neither "alpha" nor "beta") but I'll occasionally argue that a well-presented and well-supported alpha should not cause terror. …" "… a chat app that is alpha is one thing, a filsystem implementation that is alpha is a whole other thing …" "… if I would have seen the 'alpha' word there, I wouldn't have made the jump to OpenZFS, I'd probably be using the old MacZFS, at most … alpha may be attractive for developers, but it scares general public, like me …"

  • Atomares Schreiben" bei ZFS bedeutet, dass der Schreibvorgang einer Datei entweder ganz oder gar nicht stattfindet. Wenn du also den Stecker ziehst, hast du entweder den alten oder den neuen Zustand, aber keinen inkonsistenten Datenmüll.
  • Die 5GB RAM für 1 TB ZFS Speicher sind durchaus realistisch
  • Würde bedeuten das ein normaler Mac zwischen 8-16 GB RAM haben müsste, besser 16 GB.
  • ZFS zusätzlich zum eigenen Code erst einmal nur ca. 64kB je gemountetem FS um zu funktionieren und z.B. mindestens 64 MB für Log-Devices. Der Rest wird halt per default bis auf 1GB komplett als Cache verwendet und kann limitiert werden wenn es nötig ist, oder wird vom System bei Bedarf freigegeben.
  • Man KANN alle Features von ZFS nutzen MUSS man aber nicht.
