Hello All Im new in solaris 10 zfs structure.my machine is ultra-sparc server with 5 scsi hards. data protection for my solaris operating system is important for me,so i want all of my hards participate in one pool and build raidz construction. in solaris 10 installation process,when it shows the zfs configuration(rpool name and size,...) i saw that it takes just one of my hards for building pool,not all of them.but i want to make all of my five hards to raidz structure. should i add other hards to default pool(rpool) after installation? can i have one pool with five hard drives and build raidz on it so that my operating system installed on it and has redundancy and data protection?if yes how?

The best you can do right now is mirroring. During the install, choose more than one hard drive and zfs will create a mirror configuration. Support for raidz and/or striping is for a future project.

Just to add -- this is a boot disk restriction. Solaris 10 supports RAIDZ just fine, but not as a boot disk. Boot disks can only be mirrored. So you could use a couple of disks for a pair of mirrored boot disks, and then create a new RAIDZ zpool from the remaining 3 disks to use for data. -- Andrew Mark J Musante wrote:> The best you can do right now is mirroring.

Hello Allris can i add second hard for building mirror boot disk after installation? or better reinstalling solaris operating system and make mirroring during installation?

Dear All thanks for your guide I dont remember that in the installation process,after selecting zfs file system,it let me to select additional disks or not? can i select another c0txdy for creating mirror? or it must done after installation?

Iman, Yes, you can do either of the following: o Select two disks for creating a mirrored root pool during an initial installation o Attach a second disk after the initial installation, like this: # zpool attach rpool old-disk new-disk In the attach disk scenario, you will also need to add the boot blocks due to an existing bug, like this: sparc# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk new-disk The initial install does this step automatically.

Iman,
Sure, just select both disks during the install, like the screen below.
If you don''t see all the disks on the system during the initial
install,
then either their is an underlying configuration problem or you just
need to scroll down to see all the disks.
Cindy
Select Disks
On this screen you must select the disks for installing Solaris
software. Start by looking at the Suggested Minimum field; this value is
the approximate space needed to install the software you''ve selected.
For ZFS, multiple disks will be configured as mirrors, so the disk you
choose, or the slice within the disk must exceed the Suggested Minimum
value.
NOTE: ** denotes current boot disk
