Re: [zfs-discuss] ZFS Tutorial at LISA09
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 Sproulespr...@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.

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.
