Is it possible to create flar image of ZFS root filesystem to install it to other macines? -- This message posted from opensolaris.org

Hi RB, We have a draft of the ZFS/flar image support here: http://opensolaris.org/os/community/zfs/boot/flash/ Make sure you review the Solaris OS requirements. Thanks, Cindy On 09/14/09 11:45, RB wrote:> Is it possible to create flar image of ZFS root filesystem to install it to other macines?
As an alternative, I''ve been taking a snapshot of rpool on the golden system, sending it to a file, and creating a boot environment from the archived snapshot on target systems. After fiddling with the snapshots a little, I then either appropriately anonymize the system or provide it with its identity. When it boots up, it''s ready to go. The only downfall to my method is that I still have to run the full OpenSolaris installer, and I can''t exclude anything in the archive. Essentially, it''s a poor man''s flash archive. -Greg Cindy.Swearingen at Sun.COM wrote:> Hi RB, > > We have a draft of the ZFS/flar image support here: > > http://opensolaris.org/os/community/zfs/boot/flash/ > > Make sure you review the Solaris OS requirements. > > Thanks, > > Cindy > > On 09/14/09 11:45, RB wrote: >> Is it possible to create flar image of ZFS root filesystem to install >> it to other macines? > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > >
Hi Greg, We did a hack on those lines when we installed 100 Ultra 27s that was used during J1, but we automated the process by using AI to install a bootstrap image that had a SMF service that pulled over the zfs sendfile, create a new BE and received the sendfile to the new BE. Work fairly OK, there where a few things that we to run a few scripts to fix, but at large it was smooth.... I really need to get that blog entry done :) /peter Greg Mason wrote:> As an alternative, I''ve been taking a snapshot of rpool on the golden > system, sending it to a file, and creating a boot environment from the > archived snapshot on target systems.

I tired to install the flar image using the method explained in this link
http://opensolaris.org/os/community/zfs/boot/flash/
I installed 119534-15 patch on the box whose flar image was required. Then
created a flar image using
flarcreate -n zfs_flar /flar_dir/zfs_flar.flar
I then installed 124630-26 patch on the miniroot of Solaris 05/09 (update 7)
net install image. This was done by unpacking the miniroot using root_archive,
patching the miniroot using patchadd and then repacking it back.
Profile for the jumpstart :
install_type flash_install
archive_location nfs <ipaddress>:/<flar_dir_path>/zfs_flar.flar
partitioning explicit
But the jumpstart fails with the following error:
Executing SolStart preinstall phase...
Executing begin script "install_begin"...
Begin script install_begin execution completed.
Processing profile
- Opening Flash archive
ERROR: Could not mount <ipaddress>:/<flar_dir_path>/zfs_flar.flar
ERROR: Flash installation failed
Solaris installation program exited.
Any clues what could be wrong?
Thanks.

There''s all kinds of reasons a nfs mount might fail. One think you could is to boot the system from the install image and then escape out of the install after going through all the configuration steps (i.e. the questions about name server, routers, etc.). Then try to do an explicit NFS mount of the flar location (onto /mnt or a temporary mount point created in /tmp). If it fails, that may be the source of your problem. lori
Hi Peter, Do you have any notes on what you did to restore a sendfile to an existing BE? I''m interested in creating a ''golden image'' and restring this into a new BE on a running system as part of a hardening project.
