It looks like I'm going to need to grow in the near future. Any tips for a procedure for this? My current plan: 1. Add a PCI SATA controller (MB had 4 SATA + 4 RAID SATA, it's a Tyan MB with a NFORCE chipset, I'm not sure if I want/can use the RAID SATA ports as plain SATA connections). 2. Add 2 more drives - not necessarily the same size as the existing (they were all 4 the same) 3. Execute "mdadm --grow /dev/md0" -- Daniel
