I'm trying to install Fedora 10 86_64 on a 64 bit system with a Dell PERC Raid5 controller. It installs fine, but on bootup it comes back with VolGroup00 not found, other errors, and refuses to boot.

This machine ran FC9_86_64 just fine until we went to bigger disks and tried to reload.

Checking the single DVD from Fedora_86_64 says it tests ok. Tried it twice now. Any hints ?? TIA!

When I installed Fedora 10 I just used the defaults for creating the file system partitions. I didn't check or modify any of the default settings.

FC9 loaded and ran fine on the machine (although eth0 is not activating on boot for some reason..) One of the other Forums sent me a work-around, but I lost it. It's modifications of the boot sequence and timings in FC10, and apparently can be done from the rescue disk process. If I find it again, will post it. For now, staying with FC9.

I figured this out after doing more google searches. Turns out this is a known issue with the scsi initialization not waiting long enough. You have to rebuild initrd with 'mkinitrd' and use the --with=scsi_wait_scan

Boot off the install DVD and go into rescue mode.
Cd the mounted root for the hard drive with new installation. Then do a "chroot" so you are now operating on the installed disk drive.

next run the following command:

mkinitrd -f --with=scsi_wait_scan /boot/initrd-2.6.27.5-117.fc10.x86_64.img 2.6.27.5-117.fc10.x_86_64

This will install a new initrd in /boot.
Now reboot. Should work.

The only issue after this seems to be a bad name resolver library that is causing yum updates to fail because it can't resolve some repository host names. That was fixed by hardcoding some of the mirror sites in /etc/hosts.

... Moving on to other hurdles ...

use 'scsi_mod.scan=sync' as an additional item on the kernel boot string.

You can boot into your OS and do the mkinitrd to fix the issue.

Warning: a yum udpdate afterwards caused my system to require another go at this procedure ... so watch your updates ... it will break things.

By the way ... It's all SCSI type cards ...
for example my system was Sata Drives on a 3ware card.

Thank you very much. It worked for me on a HP Proliant ML150 server.

/sbin/mkinitrd -f --with=raid10 --with=raid456 --with=aacraid --with=scsi_wait_scan /boot/initrd-2.6.27.9-159.fc10.x86_64.img 2.6.27.9-159.fc10.x86_64

Thank you. It works on my IBM xSeries 360 too.
