Hi,
I'm migrating a webserver(apache+php) from RHEL to solaris. During the
stress testing comparison, I found under the same session number of client

After some investigation, zfs root lock emerges as a major doubtful point.
Firstly, t
I have a USB disk with opensolaris200906 installed.
I'm using it to test OS on the different boxes.
Recently(B109, B110, B111) I run into a weird problem from time

Hi Folks,
I'm trying to backup my /export folder to an USB disk by zfs send/receive.
But zfs receive try to mount the dataset to a mountpoint which is already

Hi list,
for windows we use ghost to backup system and recovery.
can we do similar thing for solaris by ZFS?
I want to create a image and install to another machine,
So that the personal configuration will not be lost.

Hi all,
I'm new to zfs.

So I want to upgrade kernel by my own image.
Following the cap-eye-install, I got a tar ball and extract it under "/".
I also added a entry in /rpool/boot/grub/menu.lst to boot my own kernel.
