You sure? That would be a bug in 2.4.18...
ext2 does not know how to mount a needs-recovery ext3 filesystem. It is flagged as an incompatible feature (4 -> EXT3_FEATURE_INCOMPAT_RECOVER).
If you run journal replay by mounting it with ext3 or running fsck across it, then ext2 can mount it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
