Sun Solaris, OpenSolaris Sun Microsystems has delayed the release of two major features the company has trumpeted as reasons to try its latest version of the Solaris operating system. Eric Schrock, a Solaris kernel programmer, said on his blog in April that he's "completely redesigning the ZFS commands from the ground up" after finding some deficiencies.

ZFS and Sun

<Sharman>You're new to Sun, aren't you?

Yes and no. I've done QA work on Sun boxes, and
we've got about half a million dollars worth of
Sun hardware from about 4 years ago, but I'm not
privvy to the inner workings of Sun management and
tech support.

I have, however, followed the evolution of Linux JFS'es
fairly closely (to within the limits of my understanding),
and I do understand that there are some severely contradictory requirements (speed versus reliability, large vs small files, etc) that must be juggled very carefully.

The fact that Sun made significant errors in developing ZFS is not astounding - it could easily happen to a team of highly skilled engineers, and I'm sure Hans Reiser had his
share of bitter revelations too.

The problem is simply a matter of hype - you push an unready product too hard and you have to accept that people will come down on you like a ton of bricks if you badly fail to meet their expectations of when it will be ready.
