I haven't been able to make much progress these last couple of weeks due to school projects and exams, however there have been a few bug fixes and performance improvements. Thank you to everyone who reported bugs and sent patches (and suggestions)!

I expect to release alpha2 in the next few days, after some newer functionality is implemented.

Interestingly, Patrick Verner has been busy adding support for zfs-fuse in his Parted Magic LiveCD/USB project, which is now officially the first Linux distribution supporting ZFS!

Seems very cool, so if you want to test zfs-fuse but don't feel like compiling it yourself, give it a shot ;)

Oh, and I've created a zfs-fuse discussion group, following the suggestion of Miguel Filipe :)

By the way - if you encounter any unexpected problem using zfs-fuse, please report a bug or post a message to the zfs-fuse discussion group, otherwise I can't fix it..

No way to submit bug without creating account? So I'll post here:

zpool import don't work, because is uses non-linux default:

cannot open '/dev/dsk': No such file or directory

Running zpool import -d /dev works;

Suggestion: search for devices in /dev, not in /dev/dsk.

Thanks for great work!

Fixed in 0.4.x and trunk.

Thanks for reporting.

Wouldnt call parted magic a distribution.

So what is going to be the first linux distro to include zfs ?

Great job you're doing :-)

Is it feasible to use this for semi-important data right now? I don't care about performance, just data integrity and forwards compatability with later versions.

I'm wondering because i've just built a fileserver and trying to decide on filesystem. If i'd go for something else i'd have to migrate the data later :-)

Well, the current version should never cause data loss (I can't give you any guarantees, of course). The disk format is also stable, so you shouldn't have problems with forward compatibility.

The main problem right now is very high memory usage. It's not possible to control it yet, see bug #9838.

If you decide to use zfs-fuse for semi-important data, I advise you to use the mercurial version as of today, which should be pretty stable.

In the next couple of days I'll introduce a change (the multithreaded event loop) which could lead to some instability, so watch out for that.

Still quite slow to the single disk/partition pool:
# dd if=/dev/zero of=TYHJA bs=1024k count=500
500+0 records in
500+0 records out
524288000 bytes (524 MB) copied, 96.6561 seconds, 5.4 MB/s

While to the ext3 software-raid1 disk it's 17MB/s.
