Hey All, I have two hard drives in my system: sda=40 Gig and sdb=70 Gig. The following partitioning scheme works fine: zerombr yes clearpart --all part /boot --size 16 part swap --size 1024 part / --size 250 part /usr --size 2000 part /var --size 2000 --grow part /usr/local --size 2000 part /home --size 2000 part /data --size 70000 --grow ##(this is the 2nd 70 gig hard drive) I wanted to place a smaller size along with the grow switch in for the 2nd hard drive in case not every system has that large of a drive. If I use anything smaller than 67,000 for the size (I've tried 5 different sizes ranging from 2,000 to 60,000), I get a kernel panic when I reboot. Here are the last few lines I see when I reboot. Partition Check: ##info for sda SCSI device sdb: 143374741 512-byte hdwr sectors(73408MB) sdb: sdb1 sdb2 < sdb5 > Kernel Panic VFS Unable to mount root fs on 08:0a If I use 70,000 for the size and the system reboots successfully, the Partition Check during startup looks a bit different. Partition Check: ##info for sda SCSI device sdb: 143374741 512-byte hdwr sectors(73408MB) sdb: sdb1 Does that mean anything to anybody? I don't see any errors on the virtual consoles during kickstart. And when I do a "df -h" at the shell prompt during kickstart, it seems like the 2nd hard drive never fills up all the space. For instance, if I said "part /data --size 20,000 --grow" the available space is about 57Gig and if I do "--size 2,000" the available space is 31Gig. I know multiple grow commands don't work well but I assumed that meant multiple grow commands on one drive. Is that what my problem is? I am using Redhat 7.1. Any thoughts or advice would be appreciated!! Regards, Rebecca
