Error #1: assuming someone else's experience will have anything at all to do with yours. When doing things like this, you need to just test it yourself with your data and see what happens. And as I always preach, "testing" doesn't stop at "I built it and it works!" Experiment with failure modes, look at how you move data to a new machine when you need to, etc. Your performance will depend greatly on your hw and your data. Error #2: When you create a single file system that big, you are usually Doing it Wrong (or at least, sub-optimally). You really should be "chunking" your data into more manageable chunks if at all possible. Some of the benefits to "chunking" your data: * If you can RO "full" file systems, your fsck time drops to zero for those. * You buy storage when you need it instead of in advance. Since storage almost always gets bigger and cheaper, delaying storage purchase makes a lot of sense. * Even with modern hw, a gigabyte of data takes a while to move. A terabyte takes a long time to move. * Someday, you will need to upgrade/replace the hardware. Chunking your data gives lots of options here, which might be the difference in doing a hw replacement/upgrade in a routine hw maintenance window vs. spending a very long weekend down. * When something bad happens, you may spend a lot less time recreating your data.
