I will be hosting a ZFS tutorial at the USENIX Large Installation System Administration (LISA09) conference in Baltimore, MD this November. http://www.usenix.org/events/lisa09/ I will need to submit the presentation materials by September 14, 2009. If you were to attend, what subjects should we cover? Remember that the bulk of the audience is expected to be system administrators and we simply won''t have time to do a source code dive. -- richard

Also, the benefits and issues associated with adding SSDs to the mix. Based on the last zfs talk I attended at a LISA, system administrators are largely interested in system administration issues.

I''d also like to hear about how people are maintaining offsite DR copies of critical data with ZFS. Just send/recv, or something a little more "live"?

I won''t be able to attend, but being subscribed to this list and the storage list for a short while, the following topics would come to mind: - ZFS pool layout tips (not possible to grow RaidZ, proper planning, when to not use RaidZ for high IOPS volumes etc.) - how to best handle broken disks/controllers without ZFS hanging or being unable to replace the disk - how to do proper troubleshooting and performance testing (especially trying to isolate if the issue is in ZFS, iSCSI, NFS, CIFS, etc). - how to determine if an SSD for my ZIL or cache is going to improve my throughput That would be my personal wishlist. I hope the presentation will be made public after the event. ;-) Thanks, Marcus On Fri, Aug 21, 2009 at 4:10 PM, Eric Sproul<esproul at omniti.com> wrote:> Bob Friesenhahn wrote: >> An obvious item to cover is the new Flash Archive support as well as the >> changes to Live Upgrade due to zfs boot. ?Also, the benefits and issues >> associated with adding SSDs to the mix. >> >> Based on the last zfs talk I attended at a LISA, system administrators >> are largely interested in system administration issues. > > +1 to those items. ?I''d also like to hear about how people are maintaining > offsite DR copies of critical data with ZFS. ?Just send/recv, or something a > little more "live"? > > Eric > > -- > Eric Sproul > Lead Site Reliability Engineer > OmniTI Computer Consulting, Inc. > Web Applications & Internet Architectures > http://omniti.com > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss >

I realise it''s something that Sun probably consider "fixed by the disk/controller drivers", however many of us are using opensolaris on non-sun hardware, and can''t necessarily test in advance how the system is going to behave when things fail! So any techniques available to mitigate against any entire pool hanging because 1 device is doing something dumb would be very useful. I guess that might move away from "pure zfs" in terms of tute content, but as a sysadmin, it''s the whole system we care about!> That would be my personal wishlist.
