I'm formatting a filesystem on a new 2TB disk. It will be used to store
video, so it will just contain a relatively few large files (200KB to 10GB).
So, worst case, i need 10000 inodes.
First I used the option "-i 100000", this resulted in 20 million inodes in
the filesystem.
Next I used the option "-N 30000", this resulted in 238,000 inodes.
Is the math broken in e2fsck, or am I doing something stupid?
There is a lower limit to how far you can go.
Using -N 30000 should have got you there.
The last time I messed with it (5+ years ago) the limit was 4MB/inode
and when you gave it an N value lower than that, you got the 4MB/inode
value.
It sounds like the limit is now 8MB/inode as that would give you about
238k inodes on around 2TB...
Thanks! I can live with it. Just wanted to know if I was getting senile
or what.
