I find it baffling that RaidZ(2,3) was designed to split a record-size block
into N (N=# of member devices) pieces and send the uselessly tiny requests to
spinning rust when we know the massive delays entailed in head seeks and
rotational delay. The ZFS-mirror and load-balanced configuration do

Hi,
I'm "smbsharing" ZFS filesystems.
I know how to restrict access to it to some hosts (and users), but did
not find any way to forbid the smb protocol being advertised on a
specific interface (or the other way around, specify the ones I agree with).
Is there any other way than setting up a firew
I have used these cards several UIO capable Supermicro systems and Opensolaris,
with the Supermicro storage chassis and up to 30 stata 1Tb disks.
With IT mode firmware (non-raid) they are excellent. They usually have the
"hardware assisted" raid firmware by default.
The card is designed for the

I had to use the labelfix hack (and I had to recompile it at that) on 1/2 of an
old zpool. I made this change:
/* zio_checksum(ZIO_CHECKSUM_LABEL, &zc, buf, size); */
zio_checksum_table[ZIO_CHECKSUM_LABEL].ci_func[0](buf, size, &zc);
and I'm assuming [0] is the correct endiannes
Thanks for the response Marion. I'm glad that I"m not the only one. :)

Well it appears that the pci-x version of the card might or might not work with

Last night I was trying to setup nfs to share a pool. It was working fine until
I started to have trouble writing. I did a zpool status to see if everything
was ok, and I got this.

Well, I still don't understand Apple. Apple likes to get a grant for an
