Did I imagine it when I typed RAID1 in my previous e-mail? I meant to
make it clear that this was feasible using NO RAID, or using RAID1.
Generally, when you have a data storage system that you want to add
extra disks to on an adhoc basis (the subject of this conversation) you
probably want something more economic than RAID1 volumes.
But yes - I'm glad you agree with me that it is possible using RAID1...
just not so useful in the general case :-)
