They "lean on ZFS" for DAS.

Seriously. You tell me. What does that have to do with your rant on ZFS? It could have as well been an LSI controller doing RAID6. Or mdadm. Doesn't matter.

That's the evolved solution they came up with.

The "networked storage is broken" pitch actually comes in with the EMC/NetApp interim solution as well. I don't buy it either, but it's a joke to claim the problem was ZFS on the Zones when the Targets weren't running ZFS.

You're awfully prickly, but I didn't suggest it came down to "Enterprise" NAS vs DAS. I actually think networked storage is here to stay (and that's a good thing).

I have my doubts we'll see a stable, inexpensive (or free) Distributed or Clustered file-system ready to replace traditional solutions anytime soon. I'm happy to see people try though.

You clearly have an axe to grind with ZFS though. In my experience it's been by far more stable than any available Linux FS I've used. Pull the power again and again, replace and resilver all you want. Manage terabytes and don't worry about corruption. I wouldn't trust ext3/4fs for anything I couldn't stand to lose...

PS: http://en.wikipedia.org/wiki/Direct-attached_storage

"People who know storage". I don't see iSCSI on that list. Nor FCoE. DAS (at least according to Wikipedia) explicitly rules out switching. Which is how I've always viewed it.

You're really not getting it, are you? I never said ZFS was the problem, as you seem to think. I'm just saying it's not the solution either. It's a crappy solution, failing to protect against host failures and creating myriad problems in provisioning around the fact that each VM's storage is stranded on one node until it's explicitly copied somewhere else. And if you don't think there are decent distributed filesystems out there, you're just not keeping up with the field and shouldn't be commenting on it.

I don't think I am getting it no. You don't think ZFS is the problem?

So you aren't calling ZFS a "crappy solution"? Just the DAS usage?

What is your gripe exactly then? The overblown critique of networked storage? Well we agree on that at least then. I think.

Honestly, with all the "read the fucking article", it's-not-DAS, oh-it-is, CloudFS is way moar better than ZFS, I never said ZFS sucked, "Bryan ZFS Cantrill is a jackass" you've left me absolutely bewildered at what your intended point (if any) actually is?

For the record, my only comment on (free) distributed filesystems (that aren't vendor-locked and actually unusable to me) is that I wouldn't personally trust them with my data. Not until they have the features I need, and then are running out in the wild, widley deployed for a couple years so I'm not a guinea pig.

I'll even throw you a bone: Even just last year ZFS was having major melt-downs when a new inadequately vetted feature was added. A few years ago it wasn't uncommon to face corruption when trying to do fairly routine things managing disks. Bugs can and do happen.

Maybe CloudFS, or Gluster is ready for prime-time, housing terabytes of data reliably and never making a misstep. I just don't think it's smart to bet your business on it. Not at least without a plan B since moving data around isn't an option when you're down and have terabytes you need to get back online.
