Say I have 8 drives:
- Four 1TB
- One 1.5TB
- One 750G
- Three 500G
If I put all of these in a RAIDZ2 pool, how much space should I have? I put them all in a pool, and I ended up with 2.7TB (2.6TiB). Obviously, ZFS is able to use different size drives. But I'm wondering why I don't have more space. What's not being used here?
I also know that this isn't the best configuration for performance. I'm not worried about that, I'm simply storing large files that are infrequently accessed, so performance is not an issue. A write speed test to it showed around 150MB/sec (1200Mbit/sec). That's fine for what I'm doing.
If I take out a 500GB drive and put in a 4TB drive, how much will my available storage go up? What about with a 3TB drive?
I'm just trying to understand how things are allocated so I can plan for buying larger drives.
