Comprehensive diagram of the ZFS structure

[Bidule0hm]

As someone has asked questions about ZFS structure and as I'm a fan of ASCII art...

Code:

Just to be a pedantic PIA, what about the ZFS dataset that's created automatically and shares the same name as your pool?

Otherwise:

Code:

★░░░░░░░░░░░████░░░░░░░░░░░░░░░░░░░░★
★░░░░░░░░░███░██░░░░░░░░░░░░░░░░░░░░★
★░░░░░░░░░██░░░█░░░░░░░░░░░░░░░░░░░░★
★░░░░░░░░░██░░░██░░░░░░░░░░░░░░░░░░░★
★░░░░░░░░░░██░░░███░░░░░░░░░░░░░░░░░★
★░░░░░░░░░░░██░░░░██░░░░░░░░░░░░░░░░★
★░░░░░░░░░░░██░░░░░███░░░░░░░░░░░░░░★

It's just a dataset and as datasets can be nested it's not a problem.

Thanks :)

ANSI Art. Reminds me of my BBSing days.....years ago.....:)

this rocks....http://monodraw.helftone.com
photoshop for coders & sysadmins!

 

[Bidule0hm]

It's cheating, but anyway I'm sure I'm faster with a text editor than with this software where you move chars with the mouse... And Mac only? no, thanks :P

 

[nightshade00013]

As someone as asked questions about ZFS structure and as I'm a fan of ASCII art...

Very nice, Cyberjock should probably add that into his guide as it will probably help explain to the noobs how it all works visually.

 

[cyberjock]

I already have a visual representation in my guide.

Also a dataset does NOT have to contain a share, nor does a share *have* to go on a dataset. It's a very good idea though.

 

[Bidule0hm]

Totally forgot about that, I'll edit to add zvols and co when I've the time ;)

 

[DrKK]

I might suggest that the "pool" box be vastly larger, just for psychological reasons.

 

[Bidule0hm]

Ok, why not ;)

 

[Bidule0hm]

I edited to make the changes ;)

 

[Fuganater]

This needs to be a sticky.

 

[Bidule0hm]

Thanks ;)

 

[cyberjock]

I'm actually against this being a sticky. Some changes are being made in FreeNAS 10 that will break that ASCII art. In fact, it will be incorrect in 10. Sorry, but I won't go into more detail at this time as things aren't 100% decided on how it will work.

Thanks.

 

[Tywin]

Sorry, but I won't go into more detail at this time

Typical.

Delphic much? :)

 

[Bidule0hm]

Well, I can always add "9.3" in the title and/or make another version for FreeNAS 10 ;)

But I don't understand why it would be different because it's the ZFS structure, not the FreeNAS structure.

Well 10 is not offical yet so that does not matter. This is accurate to the current version. When 10 comes out, by all means unstick it.
