RE: qnx6f max file number
Each inode requires 128 bytes, so 100M inodes is 12.8GB, plus the
indirect blocks. Finding a free inode in a mostly-full system would be
time expensive at that scale. What you are saying is that you expect
your 2TB drive to be filled up with 10KByte average-sized files. Having
said that, I know that the test group here has a 2TB server set up with
10M inodes.
mkqnx6fs uses the hint of -T to guess at the average file size. The
number of inodes are then selected based on that.
The (current, but might change) values are:
Desktop: 1024 byte block, 8 blocks/file
Media: 2048 byte block, 512 blocks/file
Runtime: 1024 byte block, 32blocks/file
