EXT3 Mounting problem with USB drive.

I have a 1 TB external USB drive that is formated for EXT3. When I mount the partition, it mounts and is usable, but it mounts as EXT2. The message is:
"EXT2-fs warning (device sd(8,1)): ext2_read_super: mounting ext3 filesystem as ext2"

I've read other posts suggesting that it is a kernel issue without support for EXT3, but that is compiled in and my root EXT3 system mounts fine.

kernel 2.4.28-gentoo-r5

Thanks

AFAIK the ext3 limit for 2.4 kernels is 1TB, so if your partition is slightly over that size, it might be what your problem is.

You could try a 2.6 kernel (supports up to 4TB on ext3), or use 2 partitions on your device. Another filesystem e.g. xfs/jfs might work too.

Nope, I thought for sure that would be the issue, but I tried creating a 5G partition and formating in EXT3, but it generates the same error when I mount it.

Maybe a limitation of going through the USB/SCSI layer. I'd still suggest trying a 2.6 kernel or different FS.

Well Reiser seems to work ok, so I guess I'll use that. Takes a lot longer to mount though for some reason.
