The only thing I haven't found in zfs yet, is metadata etc info.
The previous 'next best thing' in FS was of course ReiserFS (4). Reiser3
was quite a nice thing, fast, journaled and all that, but Reiser4
promised to bring all those things that we see emerging now, like cross
FS search, any documen

Hi,
In brief, what I am trying to do is to use libzpool to access a zpool -
like ztest does.

Jens,
Someone already added it to the ZFS links page, here:

I just added a link to the links page from the zfs docs page
so it is easier to find.
Thanks,

I had a similar situation between x86 and SPARC, version number. When I
created the pool on the LOWER rev machine, it was seen by the HIGHER rev
machine. This was a USB HDD, not a stick. I can now move the drive
between boxes.

Thanks to everyone for the sanity check - I think
it's a platform issue, but not an endian one.
The stick was originally DOS-formatted, and the zpool was built on the first
fdisk partition. So Sparcs aren't seeing it, but the x86/x64 boxes are.

Couple of week ago I put together an implementation of space maps which
completely eliminates loops and recursion from space map alloc
