Disk upgrade

Disk upgrade

[Bill Davidsen]

I'm running out of room in a box to add drives, so I want to go to 
larger drives. Unfortunately I have but one bay left. What I would like 
to do is put in a single drive, create a raid-10f2 array with a missing 
device, and copying all of the data off the existing arrays onto the 
raid-10 array, then diddling the boot so I can get up off the new drive, 
removing the old drives, adding another new drive and adding that to the 
array, along with a spare, perhaps.

Any particular problems with that plan? It leaves the existing drives 
intact, and critical data is backup via rsync on both a removable device 
and to network storage.

Cases are cheap.  Buy a new case with plenty of bays and cooling:
http://www.newegg.com/Product/Product.aspx?Item=N82E16811147154
8 x 3.5" internal bays w/drive rails, 3 x 5.25" external bays, excellent
cooling, $80 USD, reuse your current PSU and internals, grab a new PSU
if needed to handle all the drives.

If you start running out of 3.5" internal bays start adding these to
your 5.25" bays:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817994095

With current 2.5" drives you can get up to 12TB raw in the 3 5.25" bays
on top of the 24TB raw available with the 8 3.5" bays, 36TB total.
