Always run filesystem tools on the device holding the filesystem, rather than some random component ;) and similartly > [root@FileServer ~]# resize2fs /dev/md0 resize2fs /dev/LVMRAID/LV0 HTH David -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
