That's some disk space there. Didn't even know that the kernel could address that much.

As a block device, Linux can't (last time I heard?).

But the above is free disk space as reported by a filesystem, which is just a 64-bit value. So it depends on the remote side's ability to address that much.

In this case, the NFS server is just on crack.

But if the NFS server did have that much free disk space, there's no reason Linux couldn't address it over a network filesystem.

But if a yottabyte is 2^80, that doesn't fit in 64 bits. Much less 65536 yottabytes, which is 2^96. Which would require a number with 2^97 bits. Even if the FS size got reported as the number of gigabytes, that's still 2^96 / 2^30 = 2^66, which doesn't fit in 64 bits.

Yeah, wtf? Good call. I didn't even think about it.

So, uh .... now I'm really curious what's going on. And that GNU "df" has that suffix known.

If it were 65536YF that would make more sense: "you're fucked"

Heh. I love the fact that the df -h actually has 65536Y. Someone planned ahead when they wrote df apparently!

What's bigger that a yottabyte though? Can I go ahead and coin it as an "assload"-byte> you sir, have 65AB of disk space free...

but even then you can't run the MS ZUNE on it :P

Zune software is compatible with the following operating systems:

Windows XP Service Pack 2
Windows XP Media Center Edition 2005 Update Rollup 2

Windows Vista
Windows Vista is not supported at this time. Check back soon for updates.

Which looks like arse because they (and xbox.com, probably same guys) sniff the browser and only return CSS if it's IE or Firefox, but not Gecko - http://www.geckoisgecko.org/ dammit.

It would be far more impressive if you could find enough data to FILL said 65536 yottabytes (not to mention living long enough to fill them at current network transmission rates) :)

Let say that you can buy 128GB disk for 1$ (LiveJournal needs a lot of disks so you have a big rebate)

Now, look:

One disk is: 128GB=2^7 * 2^30=2^37B

One YB is: 1Y = 2^80

One YB measured in $1 disks: 1Y/128GB=2^80/2^37=2^43=2^3*2^40= 8 Teradisks at $1 disk= 8T$

And you have 65563 times that.
So, congratulations, you are very rich person.

the first three times i looked at it i figured the string of numbers was an LJ formatting error o_O

then i figured it was GFS

then I realized thats like, football stadiums full of servers.

I used to be a kernel hacker at a company called YottaYotta (http://www.yottayotta.com/) that aimed to make yottabyte storage arrays. Apparently the name means drunk in Japanese. :)
