Hi again Isha,

ok, from what i can see there seems to be a lot modules
in the 2.6.9-1.667smp kernel you are using.
The initrd for the boot-image is created dynamically
during "qrm-boot-image create ..". It always reserves
some free space on the initrd for eventually additional
tools being added later (e.g. for iscsi).
The check for the final initrd size is done in the qrm-boot-image
script itself -> it checks for > 32mb because this is the maximal
ramdisk size configured in the nodes pxe-config files
( [your-base-dir]/qrm/tftpboot/pxelinux.cfg/[mac-address]  or default )

In your case this check detects "just a few bytes" more than allowed.
For now i would recommend to you to edit the qrm-boot-image script,
find the line :

    QRM_INITRD_SIZE=$(( QRM_INITRD_SIZE + 16000 ))

and comment it out to

    #QRM_INITRD_SIZE=$(( QRM_INITRD_SIZE + 16000 ))

This should make the the size-check return fine and will not cause
and problems (i think) because the resulting initrd size will
still be less than the 32mb.

btw: the next release will have a fix for that.
The number of modules copied to the intird was decreased.

Many thanks for your feedback !
Will re-check especially against the fedora core 4 distribution.

all the best,

Matt

Hi Isha,

the openQRM installation creates a default boot-image
from the kernel running on the server. This boot-image
is then used to remote-boot linux-clients by pxe.
Such booted nodes will automatically have the openQRM
client software running by a special boot-services mechanism.

In case you got an error message for the default-boot-image
creation could you please run :

  [your-basedir]/qrm/bin/qrm-boot-image create -k `uname -r` -b qrm -y qrm

and send the output ?

There is also the option to add the openQRM client software
to local booted (linux-) nodes. It is called "easy-migration"
and you can find the related programs in :
   [your-base-dir]/qrm/bin/easymigration/easymigration.tgz
Untar this on a local booted system and run the script
in /usr/qrm/bin/easymigration/qrm-configure-node-monitor.
This will add the openQRM client software to the system
and register the node in the server.

hope it helps,

Matt

Hi all


I have installed OpenQRM on Fedora core 4 distribution. But while installin=
g
OpenQRM recieved error mesage about image size too large and unable to
create boot image. But from /usr/qrm/etc/init.d I am able to start QRM
server by running ./qrm-server start. As a result I am able to add windows
clients and QRM webpage displays the same.


Problem : I didn't find any client software for unix ( linux / solaris etc =
)
clients . Does anybody know how to add unix clients to OpenQRM server ?

Thanks in Advance
Isha
