zpool list shows raw capacity, zfs list shows usable space. Compare the
output of the two. If zfs list is correct you've actually succeeded.

Failing to create a RAIDZ

Dear Members of the Group,
I bought a full tower case with 8 SATA mobo recently. So far I attached 3
HDD with 3 TB each and an SSD to have Ubuntu Server on (sdd). I installed
zfs-fuse and created my first ZFS pool
sudo zpool create data raidz sda sdb sdc
and after
sudo zpool list
I get

Whoever controls the domain, update your DNS records to make the CNAME of
zfs-fuse.net point to SANGO.RUDD-O.COM
Thanks.

Re: [zfs-fuse] Failed zpool after power removed from disk

Actually, a few days, but only now did I have a process down where it would
go any amount of time without failing in some way.
Right, just ZFS in general. Just trying to find those pockets of people
that know anything about ZFS.
Thanks.

So in short you have been trying to reimport your pool for a few hours now,
and it's still "running" (in state sleeping).
And it's not zfs-fuse specific, rather zfs specific.

Well nothing much to say here, I know some people on the sun forum have
been helpful in the past to recover some data from some zfs pools, but it's

Failed zpool after power removed from disk

I run NexentaStor and had some problems. If I told you everything that has
happened, I'd be typing for an hour. The short of it... when pulling a
dead drive to RMA, I bumped the power on another, losing the array. I have
spent a couple days trying to bring it back, but no luck thus far.
Suspecting controller issues, I moved all of the disks to another

Re: [zfs-fuse] PrivateTmp and unable to mount?

Yep it seems fedora specific, something called privateTmp.

True enough, but it doesn't sound like your mirror was perfectly intact
once you shredded one of the disks. A few misplaced bits in just the right
place will kill any filesystem, and you were doing this because one of your
drives was giving you enough trouble that you were going to RMA it. If you

I maybe have my data back. There is some c source code out there for
something called labelfix. There is an updated write function out there
from a post in 2011. I changed my write function to this. I built this
source into zpool_main.c in zpool and ran it. It returned with no input.
After this zpool import -FfVD was able to see my pool and zpool import -f

It's dying in zpool_read_label(). It reads 3 labels and then on the 4th
label it stops at this code

if (pread64(fd, label, sizeof (vdev_label_t),
label_offset(size, l)) != sizeof (vdev_label_t))
continue;

I ran a few things:

Just the line "uberblock[0]", or does it actually print the array?
(sorry for asking again, but you aren't very precise in your posts.)

There is room for 128 Uberblocks in each label, if I remember
correctly. So it should look like this (example from an old testpool

There are some more checks. As Emmanuel already suggested:

zdb -lu /dev/disk/by-id/wwn-0x5000c500 10b1613d

This prints uberblock[0] after each of the 4 labels as done previously

This fails

Passing right by it isn't unusual. That strace just reports on the
open calls done by zpool import, and these are quick, including
reading a few kb of data to look for the vdev tree.
