Filesystem 1M-blocks Used Available Use% Mounted on /dev/md0 129013 27322 95137 23% /home I guess I stuffed up with the partitioning (from fdisk): > Disk /dev/hda: 255 heads, 63 sectors, 16709 cylinders > Units = cylinders of 16065 * 512 bytes > > Device Boot Start End Blocks Id System > /dev/hda1 1 16709 134215011 fd Linux raid autodetect This was accepting fdisk's default max size. I realise this is not an fdisk mailing list but I guess you've probably hit this problem when creating large disk arrays. Could anyone please provide a quick hint on what I've stuffed up? kernel: 2.4.18 dpkg (debian woody) says fdisk is: ii util-linux 2.11n-7 Miscellaneous system utilities. the fdisk man page suggests using cfdisk... is this likely to help? it looks like a will have to recreate the raid1 array anyway. :-( matt
