I've been testing the latest 64-bit e2fsprogs from the git pu branch (kernel.org 2.6.30.5/x86_64) on a 64-bit (~22TB) filesystem for a couple days, since it seems like 32-bit e2fsprogs on a 64-bit filesystem is going to take a while longer. I'm able to create and check a filesystem without any problem. I've also run Andreas' llverfs utility for a few hours and not had any complaints. But, I'm running into another strange issue. Here's what I'm doing: # mkfs.ext4 /dev/md0 # mount /dev/md0 /mnt # mkdir /mnt/1 /mnt/2 /mnt/3 /mnt/4 /mnt/5 # umount /mnt # fsck.ext4 -C0 -fy /dev/md0 ** No errors at all at this point. fsck returns 0. ** # mount /dev/md0 /mnt The last mount command fails, and the kernel log contains: EXT4-fs: ext4_check_descriptors: Checksum for group 0 failed (3412!=9428) EXT4-fs: group descriptors corrupted! If I redo the same steps without the mkdir, or doing fsck.ext4 -fn, the mount works fine. I'm running a full llverfs run just to make sure, but it looks like it will be okay. Has anyone had success with this yet? Any other suggestions? -Justin -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
