Suns's ZFS Demo

[DaBurntToaster]

its snowing inside the video!!

[linagee]

instead of fancy green bars, linux users can run iostat. (maybe there's a way to parse this into fancy green bars with a bit of coding.)

[linagee]

"And this is a feature that is only available in ZFS" <--- and in RAID6...

[sleeplesson]

@linagee Find me a RAID6 that can rebuild that fast with large drives and I'll be impressed. The advantage is that it only needs to rebuild the data that is in the file system instead of every bit on the drive.

[ravndotdk]

Thank you for smashing working hardware. Your destructable behavior made me understand your point. Without it we would all have been clueless..

[blursst]

There's no commitment to any particular RAID hardware, meaning ZFS disk sets can be moved from system to system. As there is no RAID hardware involved, there are reduced costs and it eliminates a point of failure.

COW is pretty damn useful too.

[shid007]

OK... so it's all in one sollution, but I doubt that it would be finished in a minute or two with 2TB drives :) also what's the difference (expcept for being all in one sollution) between this and RAID6?

i bet the green bar program is a sun internal diagnostic, by engineers for engineers

[uandmeboth12]

What the program called with the nice green bars in it... i want to do nearly the same tests for a demo and would like to know the name ofthe program as its not clear on the screen ...

[THEmeggawhat]

would have been way more interesting if he had pulled out a 44 mag and blown a couple off the table.

But ZFS is the bomb.com

data correction, clone, shapshots, auto repair, what more could you want in a fs?

[THEmeggawhat]

why didnt you just unplug them Jim? silly..

[tifius]

That's a nice "desktop" system that has hot-swappable drives ;)

[Sarckz]

01:47 NOOOOO!!!!!!! =(

[Grengis]

nice demo but why did the drives have to die? :(

[viranomainen]

that yellow helmet and safety glasses on head is a little bit overacted as harddrives do not explode. :D

[RenegadeMaster07]

@viranomainen if a metal piece hits your eye, even a tiny shard, it could do serious damage. The drive doesn't need to explode.

Watch WorksafeBC safety videos on youtube to learn why everything is dangerous lol If you'd worked in construction in recent years you'd know this kind of thing is seen as necessity.

[VeggeRegge]

I wonder what can actually be done with Hammer FS since it's not available on any system that can actually be a server OS ! Worthless crap.

[berlinkeks]

Sledge Hammer -"Vertrauen Sie mir, ich weiß was ich tue!" ;-)

[VeggeRegge]

This is only one example of all that it can do.

ZFS is the best FS period. The only other FS that it can be compared is with BTRFS called ButterFS on Linux which is still in developpement and it's a copy of ZFS. Now the two project might be merged by oracle.

ZFS was rewritten with all the latest technology and it can do faster in software than many hardware raid. It also has many protection against data corruption from a defective controller...

Along with many feature, snapshot are superbe.

[killmeh2]

@VeggeRegge

HAMMER >= ZFS >= BTRFS. :P

[viscountalpha]

I would of rather seen a drive corrupted with a large magnet. Why? I want to see corrupted data entering his raid and seeing how his file system response in a realistic form. The bits start flipping or the CRC goes bad or you get some sort of failure of the magnetic coating somewhere or a head crash and things go all to shit.

A drive getting hit with a hammer is not a realistic outcome.

[africanloveturtle]

In early FreeBSD 7 there was a bug with the HT1000 sata controller where like 20% of everything was corrupt. So I had set up this zpool on a different card while we waited for the HT1000 to arrive, after installing it data would get corrupted all over the place and as ZFS tried to fix it more data would get corrupt, it was amazing to watch. when blocks for a file became corrupt on both sides of the mirror zpool status would even say something like "the file /whatever has unrecoverable errors"

[speculatrix]

@viscountalpha that depends where you work ;-)

ZOMFG

[Gruelius]

this guy could do with public speaking classes lol

[treeheadnet]

Correct me if I'm wrong but isn't this "Z2" just RAID 6 in software?

[Gruelius]

yeah zfs "z2" is like raid6 in the sense there are two drives kept for parity but ZFS itself is > software raid.

This guys a noob, could have shown many other better aspects of ZFS versus other filesystems/setups. Im no zfs expert but better error checking capabilities, on the fly volume compression, dynamically expanding columes or whatever its called. Only + i see for mdadm is the ability to add devices to raid5 arrays

I myself have a 6 disk software raid5 array with the linux MDADM driver

[hellopeople4567]

lol, nice swing :)
