I like to perform little experiments. Its my nature. Maybe I always wanted to be a scientist and dropped out of the masters program level to go get a real job with Pratt & Whitney and played with interesting materials in turbo fan jet engine blades. And I like to perform little experiments but can't stick PHd after my name. Oh well.
So I wondered to myself .. just how small a footprint can SXCR have? I know that Eric Bootilier did some interesting work with the reduced core install cluster and I was thinking of starting there and then ripping out packages until the system fell over or became just barely useable. Phase one of this experiment would be .. to start wit ha Solaris 8 system just for comparison and strip it totally bare. I did that by first creating a jumpstart server and then simply booting the system over and over and installing the core packages and then ripping out nearly everything that was left. To do that I need to have a jumpstart server and my trusty SXCR box here seems fine for the task. The Solaris 8 "add_install_client" however does not like ZFS at all and thus I had to setup everything out of my root slice. That seemed to work and I ended up with : # uname -a SunOS isis 5.8 Generic_108528-29 sun4u sparc sun4u # pkginfo system SUNWadmr System & Network Administration Root system SUNWcar Core Architecture, (Root) system SUNWcsd Core Solaris Devices system SUNWcsl Core Solaris, (Shared Libs) system SUNWcsr Core Solaris, (Root) system SUNWcsu Core Solaris, (Usr) system SUNWesu Extended System Utilities system SUNWhmd SunSwift SBus Adapter Drivers system SUNWkey Keyboard configuration tables system SUNWkvm Core Architecture, (Kvm) system SUNWlibms Sun WorkShop Bundled shared libm system SUNWpd PCI Drivers system SUNWrmodu Realmode Modules, (Usr) system SUNWswmt Install and Patch Utilities I could probably rip out a few more from that but the system really gets to be useless in a hurry. At the moment it works just fine and can even mount a remote NFS filesystem. With Solaris Express Community Release ( b35 ) on the other hand I can actuall insert each of the CDROMs and then run the setup_install_server scripts and they actuall copy everything needed into my ZFS filesystem. Great. # ls cdrom0 sol_11_sparc # cd sol_11_sparc # ls s0 s1 s2 s3 s4 s5 s6 # cd s0 # ls Copyright Solaris_11 JDS-THIRDPARTYLICENSEREADME # cd Solaris_11/Tools # ./setup_install_server /export/zfs_0/jumpstart/s10/SXCRb35 Verifying target directory... Calculating the required disk space for the Solaris_11 product Calculating space required for the installation boot image Copying the CD image to disk... Copying Install Boot Image hierarchy... Install Server setup complete repeat with other CDROMs .. easy. Then I go and look to see what I got for a result : # cd /export/zfs_0/jumpstart/s10/SXCRb35 # ls -lap total 707 drwxr-xr-x 4 root root 14 Apr 12 02:52 ./ drwxr-xr-x 3 root root 3 Apr 12 00:46 ../ -r--r--r-- 1 root root 87 Mar 2 18:33 .cdtoc drwxr-xr-x 5 root root 7 Apr 12 02:52 .install/ lrwxrwxrwx 1 root root 33 Apr 12 00:53 .install_config -> ./Solaris_11/Misc/.install_config/ -r--r--r-- 1 root root 472 Apr 12 01:16 .slicemapfile -r--r--r-- 1 root root 17 Mar 2 18:33 .volume.inf -r--r--r-- 1 root root 19 Apr 12 01:58 .volume.inf.2 -r--r--r-- 1 root root 19 Apr 12 02:12 .volume.inf.3 -r--r--r-- 1 root root 19 Apr 12 02:52 .volume.inf.4 -r--r--r-- 1 root root 6851 Mar 2 18:33 Copyright -r--r--r-- 1 root root 459760 Mar 2 18:33 JDS-THIRDPARTYLICENSEREADME drwxr-xr-x 8 root root 8 Apr 12 02:50 Solaris_11/ -rwxr-xr-x 1 root root 257 Apr 12 02:52 installer I then put in an entry in /etc/ethers and /etc/hosts and began the process : Firstly .. am I running NFS here at all ? No. # svcs -x network/nfs/server svc:/network/nfs/server:default (NFS server) State: disabled since Wed Apr 12 07:46:30 2006 Reason: Temporarily disabled by an administrator. See: http://sun.com/msg/SMF-8000-1S See: nfsd(1M) See: /var/svc/log/network-nfs-server:default.log Impact: This service is not running. I check the /etc/dfs/dfstab and there is nothign there. Good. What is the status of my ZFS filesystem ? # zfs get -o property,value,source all zfs_0 PROPERTY VALUE SOURCE type filesystem - creation Tue Apr 4 17:06 2006 - used 21.5G - available 788G - referenced 21.5G - compressratio 1.10x - mounted yes - quota none default reservation none default recordsize 128K default mountpoint /export/zfs_0 local sharenfs no local checksum on default compression on local atime on default devices on default exec on default setuid on default readonly off default zoned off default snapdir visible default aclmode groupmask default aclinherit secure default Looks good too. # pwd /export/zfs_0/jumpstart/s10/SXCRb35/Solaris_11/Tools # ./add_install_client isis sun4u /export/zfs_0 is already shared. However, the zfs file system /export/zfs_0 must be shared read-only with root access. Use the "zfs set" command to set the sharenfs property for file system /export/zfs_0 as follows: Use ro and either anon=0 or root=isis for /export/zfs_0. This must be fixed and /export/zfs_0 shared before isis can boot. making /tftpboot enabling network/nfs/server service updating /etc/bootparams copying boot file to /tftpboot/inetboot.SUN4U.Solaris_11-1 What the heck is that "/export/zfs_0 is already shared." ?? No its not. So I setup the share manually in /etc/dfs/dfstab thus : # vi /etc/dfs/dfstab "/etc/dfs/dfstab" 1 lines, 97 characters share -F nfs -o ro=isis,root=isis -d "jumpstart" /export/zfs_0/jumpstart/s10/SXCRb35 # svcadm enable network/nfs/server Then my system can finally boot via "boot net" Executing last command: boot net -s Boot device: /[EMAIL PROTECTED],0/[EMAIL PROTECTED],1/[EMAIL PROTECTED],1 File and args: -s SunOS Release 5.11 Version snv_35 64-bit Copyright 1983-2006 Sun Microsystems, Inc.

Maybe even 2GB disks. -- Dennis Clarke _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
