Hi
In the beginning of setting up linux raid-systems on our (linux)
machines at work, I ask, if there are any limitations, too.
As far as I remember, linux is able to serve 16TB at the moment (maybe I
am wrong); there of course differences between intel- and alpha-linux,
because intel-linux is 32bit system (belongs to memory etc.).
One of the simplest way to find out what has happened is to make a
mke2fs /dev/sda6 without any options.
Making a filesystem on our 32GB-stripes take about 15 to 20 minutes (SMP
machine with 2*PII 400 and U2W SCSI); in comparison your 400 GB-Stripe
will be formatted within roundabout 3 to 3 1/2 hours.
Greetings, Dietmar
p.s: I think writing superblocks and filesystem accounting information
takes most of the formatting-time; does it?
