[vox-tech] Large File Server - File System?

[Brian Lavender]

I second the LVM thing. I haven't done any benchmarks, but the added
flexibility will make life a whole lot easier. If you had a 1 TB
storage, and then you were making it 8 TB, with LVM, you can do it
without your users ever knowing. Well, except for the fact that they
will stop running out of space.

Well, there was a change in the command structure. It has been a few
months since I took a running system from 1 TB to 2 TB. But, it was
easy. New disk in, rebooted it, add the disk to the logical volume
group. Then, I just extended the partition size live. I don't know too
much about number of inodes and the block size, so I guess that is where
the tuning comes in.
