ZFS for Linux

Gullible Jones · 2005-11-02 20:19:18

Now that ZFS has been released, will the Linux kernel devs attempt to add support for it? It looks like one heck of a filesystem.

Cam · 2005-11-02 22:24:44

Link?

Gullible Jones · 2005-11-02 22:31:37

Hmm... I may have gotten this wrong. Is ZFS going to be open, or not?

rizzix · 2005-11-03 03:24:28

can't we just have hfsplus support by default... that would be good enough..

Gullible Jones · 2005-11-03 11:38:34

Does HFS+ support zettabyte-scale filesystems? Me thinks not.

(Really, what does HFS+ have that XFS, ReiserFS, or JFS doesn't?)

jftaylor21 · 2005-11-03 11:55:41

according to sun's website, "Porting to Linux is currently being investigated."

the capability to use your old macs and iPods as external harddisks..

Gullible Jones · 2005-11-03 23:19:51

Uhh... Can't you just reformat it, if you want to use it as an extra HDD?

rizzix · 2005-11-05 20:30:23

no can't do that with the ipod... (won't read on the mac)

Gullible Jones · 2005-11-05 21:20:35

Then put Yellow Dog Linux on the Mac, or something.

Seems like a whole lot of trouble to be able to read/write to an Mac formatted iPod or HD. My TiBook's logic board is cooked and I need a way to get the data off the hard drive... having HFS+ would be handy.

tomk · 2005-11-22 10:30:33

sesser, rizzix - are you aware that HFS+ support is provided by the kernel? To quote:

<src>/fs/Kconfig wrote:

config HFSPLUS_FS
tristate "Apple Extended HFS file system support"
select NLS
select NLS_UTF8
help
If you say Y here, you will be able to mount extended format
Macintosh-formatted hard drive partitions with full read-write access.

This file system is often called HFS+ and was introduced with
MacOS 8. It includes all Mac specific filesystem data such as
data forks and creator codes, but it also has several UNIX
style features such as file ownership and permissions.

It's not in the Arch kernels, so you'd have to recompile - you'll find it in File systems -> Miscellaneous filesystems -> Apple Extended HFS file system support.

nightfrost · 2005-11-22 13:05:01

why not file a request to add that module? I can't imagine it would to much of a hassle...

sesser · 2005-11-23 07:47:59

Indeed. Shortly after I got home yesterday, I compiled the module into ARCHCK and all is good. I was just making a point to make it part of the default...since about a billion other modules are included with the arch[ck] kernels already.

If you know you have all your music somewhere other than your iPod, you can go to a friend's windows machine, and format the iPod with FAT32 using Apple's iPod formatter thingy. Then it will also be readable on your Mac, linux machine, and Windows machine, all while working with itunes. Happy podding.

Jeebus. The sooner this FS gets ported to Linux, the better. :shock:

nightfrost · 2005-12-05 14:39:09

I wonder what the kernel devs think about it, considering the whole clash with Hans Reiser and his team. I'm sure if this filesystem would be included before reiser4, it would break Hans's heart in pieces.

Also, i wonder how reiser4 and zfs would compare, i.e. reiser4 + the new plugins added in 4.1...

Gullible Jones · 2005-12-05 20:32:23

Reiser4, for all the performance, is just another FS, and judging from what I've seen not that huge a performance over ReiserFS 3.6. ZFS, on the other hand, looks like it could be absolutely revolutionary. Looking at all the features, I don't think it will matter to anyone if it performs half as well as Reiser4.

As for Reiser's flaming, I could care less. He's the one with the not-quite-complete FS, so he can shut up until his code is ready.

Reiser4 is yet another FS? I thought the big fuss amongst the kernel-devs was precisely because reiser4 wasn't yet another fs, but something more/different. But, yeah, you're probably right...

However, I must say I sort of like Reiser's respectless overly paranoid pshychotic defense of his gem. It speaks to my quasi-postmodern fully-detached-from-hyperreality sense of humour...

Gullible Jones · 2005-12-05 20:58:30

Okay, it's not just another FS. It performs a bit better than ReiserFS 3.6 and its mount times are more than twice as long. Oh, and it has a plugin system that the kernel devs hate.

I'll pass, I think.

(Oh, and regarding small file performance: try making your ext3 FS with '-O dir_index -T news'. Voila, pacman is as fast as on ReiserFS.)

I just use JFS. It seems to work just as well for most stuff and it's never failed me. Can't say that about ext3.

Seems to be a no:

OMG. My jaw hit the floor. This is way different from how disk space was handled before.

Too bad Linux won't have ZFS in. I do hope however, that BSD will:

Heck, this made be think about trying out OpenSolaris this summer (if I'll have time).

Wow. Simply.... amazing. It's like LVM, but not. :twisted:
