Hi folks, The e2fsprogs 64-bit branch is available for public testing. This branch adds support for creating, checking, etc. ext4 file systems with more than 2^32 blocks - i.e., more than 16TB on most systems. This is for TESTING ONLY - don't put any data you care about on it! The public git repository is available here: git://git.kernel.org/pub/scm/fs/ext2/val/e2fsprogs.git The branch is "64bit". Known bugs: * compilation of programs using certain libe2p routines may fail (chattr, lsattr) * fsck will fail if directories contain blocks above the 32-bit boundary In general, this is very lightly tested. Please only test against the latest ext4 kernel bits from: git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git Please report bugs to this mailing list and cc'd to me if possible. I am personally testing this using a sparse backing file on XFS, e.g.: # dd if=/dev/zero of=/xfs/testfile bs=4096 seek=5G count=1 # ./misc/mke2fs /xfs/testfile # mount -o loop /xfs/testfile /mnt # dmesg | tail # to make sure it actually mounted as ext4, etc. Unfortunately, you can't use ext4 itself to host the backing file, since it has a limit of 2^32 blocks per file. Thank you in advance! -VAL -- 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
