[gpfsug-discuss] Independent Inode Space Limit

[Luke Raimbach]

Hi All,

When creating an independent inode space, I see the valid range for the number of inodes is between 1024 and 4294967294.

Is the ~4.2billion upper limit something that can be increased in the future?

I also see that the first 1024 inodes are immediately allocated upon creation. I assume these are allocated to internal data structures and are a copy of a subset of the first 4038 inodes allocated for new file systems? It would be useful to know if these internal structures are fixed for independent filesets and if they are not, what factors determine their layout (for performance purposes).

Many Thanks,
Luke.
