Adding a single 250Gb 5400RPM Maxtor disk to the 5-disk RAID5 took just over 30 hours. For future disks, we'll be adding them in multiples - if we can get pvresize working, of course. The box can take 12 disks. We're willing to take the time penalty, and in return get more space, as this box is a rsync server. The servers rsync to this box quickly overnight, then it backs up to the tape library in the early morning/during the day. This is a (relatively)cheap backup solution, and as such, doesn't need the on-line resiliancy of the file or database servers. For the file/IMAP/Oracle servers with their Sun SCSI FC raid box, we're running several raids as needs grow and aggregating them with the metadisk software.
