zfs discuss - May 2007 - setup_install_server, cpio and zfs : fix needed ?

As I saw the same issue with the previous release, I''m going to post
that
one here and not on the U4 Beta forum.

I''m trying to create a miniroot image for wanboot from the S10u4 media
(same
issue occured with S10u3 media) on a zfs filesystem on a U3 server.

SunOS jumps8002 5.10 Generic_125100-05 sun4u sparc SUNW,Sun-Fire-V240

lofiadm -a /Jumpstart/OS/Solaris10/Beta/0707/sol-10-u4-beta-sparc-dvd.iso
mkdir /tmp/a
mount -F hsfs /dev/lofi/1 /tmp/a

zfs create tank/sol10u4b

cd /tmp/a/Solaris_10/Tools
./setup_install_server -w /tank/sol10u4b/wanboot /tank/sol10u4b/install
Verifying target directory...
Calculating the required disk space for the Solaris_10 product
Calculating space required for the installation boot image
Copying the CD image to disk...
Copying Install Boot Image hierarchy...
Starting WAN boot Image build
Calculating space required for WAN boot Image
Copying WAN boot Image hierarchy...


If checking in parallel, I can see a cpio running but not doing a lot... 30
mins without activity yet...

jumps8002:/tank/sol10u4b #truss -wall -eall -f -p 27628
27628/1:        psargs: cpio -pdum /tank/sol10u4b/wanboot/interim_dir

Is that script a little bit incompatible with zfs in its current form ?

You will probably find that that there is also a find process that is
walking its way through the DVD to generate a list a files for cpio.

Have the same problem on a thumper with u3: creating a boot image there takes
about 41 min, on a U40 with b55b 2.5 min.

+ /boot/solaris/bin/root_archive packmedia $DST $SCRATCH

ON both system $SCRATCH is local UFS. $DST is ZFS on the thumper,
the same directory NFS mounted on the U40.

  21537 /bin/ksh /boot/solaris/bin/root_archive packmedia
/home/elkner/tmp/miniroot/Sol
    21576 newfs /dev/rlofi/1
      21577 sh -c mkfs -F ufs /dev/rlofi/1 385800 600 1 8192 1024 16 10 120 2048
t 0 -1 8 1
        21578 mkfs -F ufs /dev/rlofi/1 385800 600 1 8192 1024 16
10 120 2048 t 0 -1 8 1 n

Here mkfs seems to take the most time even so prstat says, load 0.02
and less (mkfs is doing nothing) ...

jel.

How about:

ptree 25751
pstack 27628
pfiles 27628

I wonder if you are having troubles with the lofi driver on top of
zfs.  If you have enough RAM, try copying the iso file to /tmp, lofi
mount it from there, then try again.

27628:  cpio -pdum /tank/sol10u4b/wanboot/interim_dir

pfiles 27628 hangs forever....

I will give a try to the iso in /tmp on a system with more memory....
