Suggested November 2023 What Does Zfs Mean For The Macintosh Platform?
Sun’s CEO Jonathan Schwartz dropped a bombshell on the computer world this week when he announced that ZFS would be the filesystem that Leopard uses. Now the mac community is probably divided into two camps on this one:
ZFS? sounds nice? Open source? good. Sun makes quality products. I’m not sure how this is going to affect me but if Apple chooses it, it must be good for me.
Holy 5H1T! That is amazing! OMFG! I mean I didn’t expect this for a few years. Now gather thoughts…few questions…
So if you are in the first group let me please suggest some reading then you can come back once we are all on the same page:
Now that we are in the second group we need to discuss a few things:
Jonathn Schwartz said that “ZFS would be the filesystem for Leopard”. This could mean a lot of things Remember, Solaris was only able to boot from ZFS in 2006, 2 years after the format was built and is still not the default format.
It could be a file system that works in Leopard like FAT32 or This has already been demonstrated on Beta builds so not big news, however very exciting for the XRAID and XSAN crowd. How Apple decides to implement it in Diskutil or another RAID type GUI application will also be interesting to see
It could be the Boot Partition which would make lots of fun things possible, like native Time Machine and really easy ways for users to add storage. I think this would be a field day for Apple’s Marketing team. Show adding 4 hard drives to a MAC and them showing up as one big volume, then showing the 4 drives on a PC. Would even allow the mac mini pro.
Some crazy combination where the OS lies on a HFS+ partition (On solid state RAM Drive or traditional Hard Drive) and the rest of the store (Applications, Library, Users) Lies on the ZFS Partition. this is obviously an interesting long shot.
Most likely, Jonatan Schwartz misspoke when he stated that it would be THE Disk format of Leopard will be ZFS and it will likely be A format that is supported, as you can already see in Leopard. It is good news, however, that it is on Apple and Sun’s radar and it is only a matter of time before it can be put into production.
Now for the downside. ZFS is a complicated file system. One that is new and foreign to a lot of companies. If you are running ZFS with a couple of hard drives on your Mac Pro, and you have a serious disk failure on one of the disks, you are unlikely to be able to whip out your Diskwarrior CD and solve the problem. It took Diskwarrior a year to work on Intel Machines, how long will it take to catch up to a new file system – after 20 years of HFS and HFS+?
The idea (in theory at least) is that ZFS can be set up to miror drives or RAID drives and will do this transparantly to the average user. Of course I’ll let someone else to be the first to roll this out to their users.
Another interesting area that the ZFS file system will allow the MAcintosh to create a sea change will be in the home theater arena. Currently, when you run out of space (and with higher quality music, more megapixel cameras and HD videos coming out , you will) you have to add another hard drive to your machine. This can range from plugging in an external USB Drive to going under the hood and installing some more SATA drives to your rig. Then you have to format your drive and add it to the list. Then you have to remeber which drive you put everything on…
Let’s see Windows do that!
