Did a fresh install and got the same problems as before. 4. Poked around in the BIOS to ensure that there were _no_ Fake RAID settings active. 5. Sigh, okay lets try the 3Gb/s channel ... (face palm!) On opening the box I noticed the drives were plugged into the GSATA3 ports. Under a normal viewing angle the 'G' was occluded by the plug mounts and it wasn't until I took a real close look that I noticed this. The positioning of the GSATA3 ports on this board was the same as the normal SATA3 ports on the previous board I used and, I confess, I didn't read the manual carefully enough shame face. Apparently the GSATA3 ports are controlled by a Marvell 88SE9172 chip rather than the Intel Z68 chip. After swapping over to the normal SATA3 ports and rebuilding, updating, installing, everything is fine :-) Thanks to everyone for their helpful comments and advice. Cheers!

My understanding of it is, the inode number is its physical position on the disk. if the first 1TB (2^31 * 512) of the disk has no free space to create an inode for a new directory, then that inode requires 64bits. http://xfs.org/index.php/XFS_FAQ#Q:_What_is_the_inode64_mount_option_for.3F -- john r pierceN 37, W 122 santa cruz ca mid-left coast ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
