Adrian Fogge Posted October 3, 2007 Author Share Posted October 3, 2007 ZFS is a filesystem that was designed by Sun Microsystems. It's core benefit is that it is a fully versioned filesystem, allowing multiple previous versions of one file to be stored with near zero overhead to the filesystem. This is because the previous versions only store what had changed in the file, allowing the meta-files to be built dynamically from the data on the disk. Additionally, it allows one to build dynamic RAID Arrays by simply adding storage capacity to the "pool". The largest benefit of the filesystem is the way that data is stored and accessed. It will perform checksums on all data to detect file corruption and then automatically rebuild the lost data. It will also automatically reorder data based on patterns in how it is accessed. Additionally, instead of a standard file system table as is used in most file systems for indexing, it uses an actual database entry that can be read strait from the disk into the drive's memory for immediate access to all metadata for all files on the whole partition. Very amazing stuff. Link to comment Share on other sites More sharing options...
foofoorabbit Posted October 3, 2007 Share Posted October 3, 2007 I really want ZFS. If full read/write and boot support comes to 10.5.x, I will dump HFS+ for ZFS on the spot. A lot of people say that ZFS doesn't do much for consumers but is mostly targeted at enterprise servers...but I see right through them...I call {censored}...what they're telling me is {censored}. I want corruption-free data...I want my 3 HDs to act and feel like one big ass 1.5 TB HD ... and I want Time Machine to work using ZFS. That last one is not gonna happen but maybe 10.6 will bring that option. Link to comment Share on other sites More sharing options...
asap18 Posted October 3, 2007 Share Posted October 3, 2007 Hmm... Apple seems to say in the notes it requires GUID. does this mean PPC macs cant use zfs? I think so. Link to comment Share on other sites More sharing options...
Adrian Fogge Posted October 4, 2007 Author Share Posted October 4, 2007 Well, PPCs can read GUID partitions. They just can't boot from them. Link to comment Share on other sites More sharing options...
foofoorabbit Posted October 4, 2007 Share Posted October 4, 2007 Is this a secret way of telling us that it's now possible to boot from a ZFS (GUID) volume? Link to comment Share on other sites More sharing options...
Gooly Posted October 4, 2007 Share Posted October 4, 2007 ZFS is excellent fs which allows the inodes to grow dynamically. Check out for zfs.kext in leopard. Link to comment Share on other sites More sharing options...

mr.manatane Posted October 4, 2007 Share Posted October 4, 2007 A lot of people say that ZFS doesn't do much for consumers but is mostly targeted at enterprise servers...So a lot of people are stupid. Almost all OS technologies for consumers came from the enterprise servers.like say it is working and i switch from HFS+ to ZFS what would i notice? http://opensolaris.org/os/community/zfs/whatis/Hmm...

Synaesthesia Posted October 4, 2007 Share Posted October 4, 2007 We've gone through this before though. ZFS would be so awesome, but then Apple officially annnounced it's not going to be the main OS filesystem. But then, Steve did also say the iPod would "never" get video...

It will also automatically reorder data based on patterns in how it is accessed. ######## lets think about that. Doesnt it mean we wont be able to add or modify a *.kext or a *.plist ? if true [and i dont understand ZFS] that would be a negative benefit, huh?
