Last night's SOSUG
was a roaring success. We had a fairly full room --- about 30 people --- come along to hear Bryan Cantrill
talk about some of the new stuff he's doing with DTrace
. Oh, and a few people were interested in hearing me talk about ZFS
The slideware for the talk is here
if you are interested.
reckoned that I wouldn't be able to give that talk in under an hour, and he was right. (At StorageNetworkingWorld last month I didn't take questions, skipped a few slides and didn't breathe in order to deliver it in 15 minutes. Urk!) It was great being able deliver to a group of people who are the ones going to see a direct benefit to their daily lives if they migrate to ZFS
. I said to one attendee that if he migrated his environment to ZFS
then he'd be able to spend more of his time on the interesting stuff that he wants to do, rather than the tedious storage admin that he has to do at the moment with SVM, VxVM, UFS and VxFS. And when we got to the admin commands example (slides 20-23) everybody was able to see that it was so.
I even got some questions from Brendan Gregg
which sounded like Dorothy Dixers
but which really, really weren't --- and I was able to say "Wait a sec, that's all on the next/second next/... slide" and it was and he was happy
Enough about me... Bryan Cantrill
was the real star of the evening.
He's out here for a few days to present a tutorial and plenary address at AUUG's 2005 Conference
. So of course he's being dragged to customer meetings all over the country while we've got him. He flew from LAX
direct to Brisbane
, did a few meetings there, hopped on a plane to come to Sydney
, came and presented at SOSUG
and then tomorrow afternoon is off to Melbourne
for some more meetings. Then I think on Friday afternoon he gets to fly home.
So anyway, back to his presentation.
Since we had about 50% of the room having actually used DTrace
, he didn't give us the fairly stock/standard presentation. He showed us some RFEs that he's implemented, not all of which have been integrated. Some of them are doozies: new options for sorting the output of aggregations, new keywords and predicates for getting to userland functions, the "-v" option to show stability levels (see attributes(5)
) and a few other things too.
I figure Bryan was somewhat jetlagged because he didn't talk at a million miles an hour.... but I reckon that every single attendee last night went away impressed with not only (cue deep off-screen voice) The Awesome Power Of DTrace but also with Bryan's skill as a presenter.
We had two video cameras going, so once Boyd
gets through with transferring the tapes (5 dats!) to disk and putting all the bits together, I'll post a followup with the link on mediacast
so you can see Bryan in full flight. It's a joy to behold
