Can this be increased to 100k like netapp? We switched over from netapp to emc and when doing the migration we didn't know that the Subdirectory has a lower limit than Netapp which made our internal application fail. We had to switch back to Netapp.
I am pretty sure it is hard-coded and cannot be changed via parameter.
If you are asking for a product enhancement / feature request than a forum isn’t the right place
in case you are wondering why
each inode in uxfs has a 16-bit field to map a parent directory to its sub-directories
the only thing you could to is to use some symbolic links that point to other dirs instead of real subdirs
