I'm having issues trying to add a disk to a Linear RAID. I'm using mdadm 2.5.4 and kernel 2.6.18. I can create a two disk linear RAID as follows: mdadm -C /dev/md0 --level=linear -n2 /dev/sata1 /dev/sata2 and all is well. I then attempt to add a third disk: mdadm --grow /dev/md0 --add /dev/sata3 for example, but only get: mdadm: Cannot add new disk to this array The new disk gets a superblock created on it matching the other two disks, but the bind_rdev_to_array call in add_new_disk (in md.c) is returning -ENOSPC. rdev->size is 160836416 (the size of the disk I'm trying to add) and mddev->size is 0. I'd appreciate any insight into what I'm doing wrong. Thanks.
