[CALUG] November 13 Meeting Announcement - ZFS Overview

[Randal T. Rioux]

Note: this email assumes Eric Sproul is on this email distribution. If
not, Chuck, can you forward?

This is awesome, and I might actually be in town for a meeting for the
first time in years!

I *just* converted my lab's collection of pcaps and malware (>20TB -
used for R&D) from HW RAID5's and SW RAID10's (ext4) to all RAIDZ
systems and I love it.

One thing that attracted me is the snapshot capability, and that I can
set gzip-7 at the filesystem level (avg 1.18x compression right now!)
and transfer are actually *faster* with compression on :-)

Caveat: I've only done this on Solaris and FreeBSD.

I realize this will be an introduction, but if I go I'll have some
hardball questions. I beat the crap out of my file servers.

One quick one now if you don't mind before the talk: what is the best
way to schedule a snapshot regimen for 1, 3, 7 and 30 days including
destroying old ones? I see scripts and stuff on the Web, but they all
look different and seem to over complicate things.

Tangent: can you tell us more about OmniOS (online info is scarce) and
whether Circonus is purely commercial (appears so)?

Thanks!
