ZFS 10th anniversary

Exactly 10 years ago today, Jeff Bonwick and Matt Ahrens got their first ZFS prototype working in user-land. Jeff had scrapped his previous attempt at reinventing filesystems, working through the established filesystem management and engineering channels at Sun, and this time started with a clean sheet of paper.

Your MDB fell into my DTrace!

Yesterday, several of us from Delphix, Nexenta, Joyent, and elsewhere, convened before the OpenStorage summit as part of an illumos hackathon.  The idea was to get a bunch of illumos coders in a room, brainstorm a bunch of small project ideas, and then break off to go implement them over...

DTrace for Linux

Yesterday (October 4, 2011) Oracle made the surprising announcement that they would be porting some key Solaris features, DTrace and Zones, to Oracle Enterprise Linux.
