snip Snapshots are significantly faster as well. My average transfer speed went from about 15MB/sec to over 40MB/sec. I imagine that 40MB/sec is now a limitation of the CPU, as I can see SSH maxing out a single core on the quad cores. Maybe SSH can be made multi-threaded next? :) i for

[zfs-discuss] Cloning a ZFS compact flash card

2009-06-28 Thread Cau Ba
I need some help please. I am currently using a compact flash as the boot drive (ZFS) on a thumper. I want to create a clone of it to a file and restore it to a new CF card on another thumper. Unfortunately, an exact make, model and size of the CF has a few less cylinders so a straight dd of

Can't you just boot from an OpenSolaris CD, create a ZFS pool on the new device, and just do a ZFS send/receive directly to it? So long as there's enough space for the data, a send/receive won't care at all that the systems are different sizes. I don't know what you need to do to a pool to

[zfs-discuss] Useful Emulex tunable for i386

2009-06-28 Thread Bob Friesenhahn
The Emulex fiber channel device driver supports a max-xfer-size tunable (via /kernel/drv/emlxs.conf) which only applies to i386. This tunable specifies the scatter gather list buffer size. By default, this value is set to 339968 for Solaris 10. Today I experimented with doubling this value
