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.
