It seems that in the initrd stage the node cannot get the modules.tgz file from the openQRM-servers tftboot/boot dir. -> the initrd only contains network-card modules. When the node boots it loads this nic-modules, brings up the network and then downloads its modules.tgz file from the openQRM/tftp server via tftp accoring to the kernel-version. In you setup it seems that the download of the modules.tgz fails for some reason. -> you need to have a look earlier in the initrd stage why the download of the modules.tgz fails. If this works ok the node will have "all" available modules before the local_deploy starts. If this does not work the node will not be able to load any additional modules. -> Could you please re-check the boot-image for this local-deploy node and its kernel version ? Also could you please check on the node in error stage what you have in /lib/modules ? > Modprobe:could not parse mpdules.dep ............. > Mountin 192.168.4.2:/home/fs_images/RH_app22 by nfs Target directory > doesn't exist ---->>(I created the directory there before) > Mount:nfsmount faild:Bad file descriptors Mount:mounting > 192.168.4.2:/home/fs_images/ on /mnt failed:no such directory > ERROR: Error grabiing image from server..... > Unable to mount storage volume...... > Starting rcS > Press Enter to activate console > ----------------------------------------------- > I replaced the linuxrc and qrm-local-disk files but still same error. > ????? > did you replaced the linuxrc within the initrd of the boot-image for the node ? -> replacing it in /opt/qrm/etc/templates/linuxrc is not enough. you need to : cd /opt/qrm/tftpboot/boot mv initrd-qrm.img initrd-qrm.img.gz gunzip initrd-qrm.img.gz mount -o loop initrd-qrm.img /mnt vi /mnt/linuxrc (make your changes here) umount /mnt gzip initrd-qrm.img mv initrd-qrm.img.gz initrd-qrm.img Then pls try again. btw: i put the openQRM-user mailing list cc. ;) all those troubles + hints may be interesting for other users too. thanks. > --parvaneh > many thanks + have a great day, Matt > -----Original Message----- > From: Matt Rechenburg [mailto:ma...@ql...] > Sent: Thursday, May 17, 2007 5:13 AM > To: PARVANEH > Cc: 'Mahesh Kunjal'; 'Ofir Reichenberg' > Subject: Re: Local-deploy issue onSCSI > > Hi Parvaneh, > > PARVANEH wrote: > >> >> Hi Matt, >> >> I wanted to grab the image from a 'Dell Poweredge 1750 with Ultra320 >> SCSI hard drive' . >> Still have problem with mounting and can not grab the image.(same MSG >> as SATA hard issue) Although at the same time mounting works on IDE >> hard on another server. >> So if the mounting has problem, why it works on another server with >> IDE hard? >> >> Just wanted to be sure that if local-deploy works with all kind of >> SCSI hard or just specific ones or ...??? >> >> > > ok, the scsi disks are detected in the intird stage (->linuxrc) by > "hwsetup". > It seems that hwsetup is not aware of your scsi-controller. > > I would recommend to check which kernel modules are needed to initialize the > scsi controller + disk.
