Description of Problem: I recently modified a working kickstart install of mine to include a separate partition for var. The old configuration had a 2048GB software raid1 across 2 scsi drives with the remainder on both disks allocated to another raid1 partition on /other (intentionally omitting swap). After installation in this configuration, with the kickstart raid patch from Bug no. 55310, everything worked as advertised. Upon updating the configuration to include a 1536mb raid1 partition (/) and a 512mb raid1 (/var) partition, then allocating the rest to /other. This leaves me with an unbooting OS. I then tried to manually step through the disk druid (leaving the packages to the kick start installation). EVERYTHING was handled by an identical kickstart file, with me to do the partitioning interactively. Old, working configuration: sda,sdb: 36GB HP SCSI LVD Drives sd[ab]1: 2048GB software RAID sb[ab]2: Grow to fill disk software RAID md0: formatted and mounted on / with ext3 using sd[ab]1 md1: formatted and mounted on /other with ext3 using sd[ab]2 New, non-working configuration: sd[ab]1: 1536GB software RAID sd[ab]2: 512MB software RAID sd[ab]3: Grow to fill disk software RAID md0: formatted and mounted on / with ext3 using sd[ab]1 md1: formatted and mounted on /var with ext3 using sd[ab]2 md2: formatted and mounted on /other with ext3 using sd[ab3] In this configuration, I get "Operating system not found" upon rebooting from the installation. THe first configuration works fine. This is RedHat 7.2 with kickstart and the patch from bug #55310. It is an HP LP1000R dual-capable, but single processor 933MHz PIII and 2GB of ram. It has non-hardware-raid 2xSCSI 36GB HDD's. Version-Release number of selected component (if applicable): RedHat 7.2 with grub 0.90-11 How Reproducible: Steps to Reproduce: 1. See Above 2. 3. Actual Results: OS Not Found Expected Results: Normal Boot Additional Information: Help?
Update: I tried this configuration and it worked: sda,sdb 36GB SCSI LVD sd[ab]1: 2048MB software RAID sd[ab]2: 512MB software RAID sd[ab]3: Grow to fill remaining, software RAID md0: sd[ab]1, ext3, mounted to / md1: sd[ab]2, ext3, mounted to /var md2: sd[ab]3, ext3, mounted to /other The ONLY change is that I used 2048MB for each part of md0 instead of 1536mb partitions.
What SCSI controller? Also, where do the cylinder boundaries lie dependent on the two different partition sizes?
The SCSI Controller is a SYM53C800. I don't know how to answer your question about cylinder boundaries (unless you can tell me how to get that information) except to tell you that the two HDs are identical. They are stock from HP and the server model is an LP1000R.
I have run into the exact same problem again. On an identically configured LP1000R, I get "Operating System not found" after using the same floppy I did to fix the first machine. I am beginning to wonder if it has something to do with both machines being factory fresh until I've tried to install them a couple times. I am attaching the ks.cfg that I used for both installs.
Created attachment 40929 [details] Kickstart file used when bug occured, both times.
Problem appears to be related to bad scsi controllers on the machine. Very strange symptom, as machine acted normal if booted via rescue floppy. Giveaway should have been when the SCSI BIOS never appeared during POST. My apologies for this waste of time.
