I've got similar problem (and it's interesting that it's not covered in Software RAID Howto).
raidhotremove will allow you to remove the failed disk raidhotadd will put the new disk into the array.
If I remember correctly, the array will rebuild itself once the new disk is added.
But do I need to format the harddrive file with fdisk before doing raidhotadd or anything like that ? or can I just plug in a new harddrive directly from the factory to the machine? If I do "fdisk /dev/hde1" and list the partiton (where hde1 is part of md0), I see that the partiton type is "Linux RAID autodetect". So I don't know if "raidhotadd' will take care of this or what (ie. creating and formating partition).
Thanks.

Once you have replaced the disk, you'll need to use fdisk to recreate the partion table & set partion types. Raid partions MUST be set to "Linux Raid Autodetect"
This is freaky, seeing the original post prompted me to check one of our servers and hey presto..... FAILED DRIVE! Don't know how long it's been down so thanks!
