My hardware is Sun V65x servers, (6GB RAM/2xXeon3GHZ/36GB SCSI disk). I have NFS repositories of Centos 3.1, Centos 3.4, Centos 4 & RedHat 9.0 ISO distros set up. I use boot floppies for each o/s with the same kickstart file which is of course altered to point at the desired distro. With Centos 4 I have to use a boot CDROM, of course, rather than floppy disk. I wish to set up servers with either Centos 3.4 or 4 versions rather than RH9. Root disk partition is 24GB btw. The kickstart boot works fine with RH9 & Centos 3.1. However it fails with Centos 3.4 & Centos 4 but in different ways: Centos 3.4 ======== The kickstart proceeds normally, formats the partitions & starts the install. However at 52% of the way through, it aborts, always on the same file: "glibc-kernheaders-nnnn.rpm" The fatal error message is non-specific & suggests that media is defective or disk space inadequate. I have checked the md5 sums of the ISOs & they agree with the download site ones. I have also extracted the "glibc-kernheaders-nnnn.rpm" from the ISO image #1 & compared its' md5 sum with the same module from the /os/ directory on the download site & they also agree. I have also downloaded the ISOs again & they are the same md5s as the first set :-\ Centos4 ======= This install gets to the point at where it would normally try & mount up the CENTOS4 NFS repository which is on the same server as all the other distros (this runs RH9). It then goes into a loop whereby it keeps prompting for the name of the NFS server & the CENTOS directory, where it would normally just mount it & proceed with the installation. Anyone out there with similar experience & a working fix for this issue please ? Les Oswald
