Hi, I'm trying a fresh install on a x86_64 (Supermicro X7dbe, 2xIntel Xeon X5450, 8 GB, 3WARE 9650SE-8LPML, 3 disks in RAID 5). The format takes quite long (2,7 TB), that seems to be normal, but then the first boot will not take place, instead the system loops. Any hints? The message follows: Regards Michael
Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init!

Hi, I'd like to add this to my problem: I tried to mount the system in rescue mode, but mount fails, the syslog says: <4>GFS2: Unrecognized block device or mount point /dev/sda2 <4>GFS2: gfs2 mount does not exist
Further top the syslog says <5>sda : very big device. try to use READ CAPACITY(16).
Any hints?
TIA Michael

Try again using a volume that is less than 2TB in size and see if it makes a difference?

In addition. I remember that my server had same problem with over 2TB logical volumes. Installation successfully is point, but can not boot it. Maybe old 3ware driver can't treat over 2TB volumes. go with nate's talk.

Just found in the 3ware manual: "Even though the Linux 2.6 kernel supports partitions larger than 2 TB, the installers for SuSE and Redhat do not. Turn auto-carving on to prevent the installation from failing." Well, it's actually not the installer, but anyways, I'll give it a try and then give you a feedback! I don't really need partitions > 2TB. Regards Michael

That's exactly how I just solved the issue - in the 3ware BIOS I defined a bootable device of 50GB for the base system and the rest was carved by auto-carving into chunks of 1024 GB. Works like a charm! Thanks for your hints! cu Michael

Hi,
You can use over 2TB partition at install from 5.1. But! only "/boot partition" must be made on smaller 2TB partition. This is maybe grub issue.
if use CentOS 5.0 try this way. 1.make 20GB partition at 3ware. 2.make 2680GB partition at 3ware. 3.install CentOS 5.2 on 20GB partition, ignore 2680GB partition. 4.after install, make 2680GB partition using "parted". 5.format and mount 2680GB partition.

sorry 3.install CentOS 5.0 on 20GB partition, ignore 2680GB partition.
