Are you trying to mount the ext4 partition using Grub? If so, mkfs.ext4 probably created 256-byte inodes, but the version of Grub that come with CentOS can only recognize 128-byte inodes. Recreate the ext4 partition using 128-byte inodes (use the -I option), or upgrade Grub to a non-CentOS version. -- Yves Bellefeuille <yan@xxxxxxxx> "Au Bellefeuille estas malkompetenta juristo au li estas malhonesta; kaj ech tertium datur: ambau malvirtoj en unu homo." -- Heroldo Komunikas, n-ro 447. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
