      Technically: ZFS at the time lacked the required feature set.

  • 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
  • ZFS pe Mac

  • ...27 more annotations...
  • Ten years ago this month, I started my professional career at Sun Microsystems
  • unique environment
  • I knew we were building something special
  • local filesystems were considered a solved problem
  • pursue that dream
  • discarding those that impeded innovation
  • it was clear that ZFS would drastically alter the filesystem landscape
  • open our eyes to the power of open source
  • “Tonic” was the code name for what would become OpenSolaris
  • led me to Delphix
  • sliced through the constraints
  • into our engineering culture
  • illumos (and its predecessor OpenSolaris) are relatively niche
  • ZFS is decidedly not
  • crossed technical and business boundaries beyond what the original ZFS team ever dreamed of
  • capture that potential and build something we are all proud to be a part of
  • building something bigger and better than anything that could ever be built within the closed walls of Oracle
  • OpenZFS is
  • a name to what we have already been doing
  • magnitude of features and improvements that can be made within our loose knit community
  • accomplish so much more
  • opportunity to build the most innovative and successful filesystem in history
  • raise awareness of the quality, utility, and availability
  • open communication
  • consistent reliability, functionality, and performance of all distributions
  • Every technology company today owes its existence in some part to open source
  • create, embrace, and evolve open source communities that build platforms for the greater benefit of the industry

shared by Graham Perrin on 09 Oct 13 - No Cached
  • August 16, 2013
  • L2ARC in memory overhead should be reduced
  • new features in Open (Illumos) ZFS. Some of the performance improvements
  • ...13 more annotations...
  • equivalents in Solaris 11 for some time
  • arc doesn't always need to make a copy
  • SUNBT6913905 IMPLEMENT ATA TRIM, SCSI WRITE SAME / UNMAP , THIN RECLAMATION
  • ZFS I/O priority inversion
  • Dedup of null blocks could use special treatment
  • What's New in OpenZFS
  • ARC metadata limit can have serious adverse effect on dedup performance
  • arc_meta_limit modernization
  • encryption, up-to 1MB recordsize, RAID-Z/mirror hybrid allocator, it does support 4k sector
  • good to see though that both Illumos and Oracle are innovating
  • LZ4 support in Illumos which is not in Solaris 11
  • they do not actively share code
  • competition might be good

  • 2013. szeptember 18
  • Kérdés hogy miután (ha jól tudom) az Oracle visszazárta a Solarisban lévő ZFS kódját, mennyire marad kompatibilis a kettő. Tehát pl. Solaris 11 alatt létrehozott ZFS mennyire olvsható/írható egy ZFS on Linux-al, vagy FreeBSD alól.

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 …"
