Site down

Hi everyone,

Recently an article was posted on LinuxWorld about ZFS-FUSE. See also the Slashdot article.

In case you're wondering why the ZFS-FUSE website is down, it's because I have been without Internet access since Monday. I never thought I'd say this again but I'm using a 33Kb dial-up connection right now (I think this might be slower than this)..

As a consequence, the Mercurial repositories are also down, and I might not receive some of your emails..

On another note, there has been recent reports of corruption in Raid-Z pools, so please backup your data before trying ZFS-FUSE!

Started using zfs through fuse for backup storage and I am constantly impressed by it. Good going - well done!

Achei muito interessante o ZFS, estou interessado sobre este filesystem.
Queria mais informações, saber como utiliza-lo em conjunto com o linux.
Quais são as principais falhas, e tudo mais.
Ta em portugues, mais sei que tu é de portugal, precisa exercitar o portugues.

Maybe with such an important project, someone could sponsor you a better connection to the Internet!

Luca said...

John, I definitely agree.

Let me know if you need it hosted still. Just email me and we can either host it off our T1 or on one of our hosted servers.

I will post a status update next Wednesday (2007-09-12).

That bug has already been fixed in the latest development code - please try the latest mercurial revision (see instructions in the ZFS-FUSE website).

'problem' with removable devices ?
ok, we have 2 usb-hd,sda and sdb,
i plug sda and i create a pool with the command:

zpool create usb1 /dev/disk/by-id/usb-HTC42602_0G7AT00-0:0

now if i export the pool usb1,zfs store ONLY sda instead of the unique id "disk/by-id/usb-HTC42602_0G7AT00-0:0"
(you can et this id whith "udevinfo --query all --name /dev/sda")
the problem is that if i plug other usb disk and than sda and than i try to import the pool usb1, it fail because it try to import 'sda' only and not the entire unique id that i have used to create the pool.
I thin zfs must store the unique id or i think there are problems with removable device.

or am i doing something wrong ? :D

(sorry for my bad english)

"zfs umount -a" try to umount also 'encfs'
mounte partitions.

and obiouvsly "zfs mount" show also encfs mounted partition(s)

To the last 2 anonymous comments - yes, known bug :(

To the disk by-id problem:

I'm not sure if I'm following you. Can you please provide a bug report with step-by-step instructions?

FYI, if you use "zpool import", it will by default scan all the devices in the top-level /dev directory for pools, and so it will use /dev/sda, /dev/sdb, etc..

If you want to import the pool by id, you can use "zpool import -d /dev/disk/by-id"
