Assuming I have a hardware RAID device that appears as a single 1.5TB drive, can I use it for UFS1 on -STABLE? The FAQ is saying: "For ffs filesystems, the maximum theoretical limit is 8 terabytes (2G blocks), or 16TB for the default block size of 8K. In practice, there is a soft limit of 1 terabyte, but with modifications filesystems with 4 terabytes are possible (and exist)." Does anyone know what the modifications are, and if they are considered stable enough for production use? -- Dan Pelleg
