Thanks for the info on the yukon driver. I realize too many variables makes
things impossible to determine, but I had made these hardware changes awhile
back, and they seemed to work fine at the time. Since they aren't now, even
in the older OpenSolaris (i've tried 2009.06 and 2008.11 now), the p

The only reason I thought this news would be of interest is that the
discussions had some interesting comments. Basically, there is a significant
outcry because zfs was going away. I saw NextentaOS and EON mentioned several
times as the path to go.

Oh well. I built LZO, and can't seem to link it in the lzop build, despite
correctly setting the FLAGS variables they say in the INSTALL file. I'd
love to provide an lzop comparison, but can't get it. I give up ... Also,
can't build python-lzo. Also would be sweet, but hey.

Hi,
i have go a problem with a zfs pool which wont resilver correctly.
The pool consists of two two-way mirrors.
One of the disks reportet checksum errors and fell out of the pool.
I replaced the faulty harddisk and switched it to available via cfgadm.
The resilver started immediately but gave

Not really. Check out the zfs send and receive commands in
the ZFS Administration Guide:

My reading of write code of ZFS (zfs_write in zfs_vnops.c), is that all the

yes, ZFS does guarantee the sequential consistency, even when there are

Where exactly do you get zstreamdump?
I found a link to zstreamdump.c ... but is that it? Shouldn't it be part of
a source tarball or something?
Does it matter what OS? Every reference I see for zstreamdump is about
opensolaris. But I'm running solaris.
