[TriLUG] Linux hard drive questions

[Maarten Lippmann]

Thats how I interpreted it too. mhddfs creates a new mount point out
of two or more existing mounts.
So you can access the underlying two partitions or disks through their
original mounts, or through the new virtual mount. If through the new
one, it adds any new files to disk1 and when full to disk2
transparently, making it look like one large disk.
If disk1 dies, there is no loss on disk2.

"Is 't noodlot, dat ick vall', van eere en staet berooft,
Laet vallen, als ick vall', met deze kroone op 't hooft,
Dien scepter in de vuist, dien eersleip van vertrouden,
En zoo veel duizenden als onze zyde houden.
Dat valle streckt tot eer, en onverwelckbren lof:
En liever d' eerste Vorst in eenigh laeger hof,
Dan in 't gezalight licht de tweede, of noch een minder
Zoo troost ick my de kans, en vrees nu leet noch hinder."
