Hi Valerie, I tried the patches and while the tools such as mkfs and debugfs seem to work fine, I am still unable to mount a filesystem with block numbers exceeding 32 bits. I am testing on a 2.6.21.1 kernel with the ext4 patches from: ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ext4-patches/2.6.21-ext4-1 The following error shows up on the kernel log: [12145.598822] EXT4-fs error (device dm-2): ext4_check_descriptors: Block bitmap for group 0 not in group (block 18446744069414584320)! [12145.670781] EXT4-fs: group descriptors corrupted! So its failing very early in ext4_check_descriptors(). The hi 32 bits of block_bitmap for the first group seem to be set all to 1s.
