Description

I'm wondering how mkfs.lustre handles --mkfsopts parameters.
We have at least -i -I -N options.
-i <bytes-per-inode>
-I <inode-size>
-N <total number of inodes>
1. How mkfs.lustre behaves if multiple options specified simultaniously , for example: mkfs.lustre --mkfsoptions='-i 131072 -N 1073741824 -I 2048'

2.If mkfs.lustre still handles paramtere when option and value are not space-delimited, for example: --mkfsoptions='-i131072 -N1073741824 -I2048'

Using -N is preferred over -i. Using "-I" is independent of the other options, unless it results in an invalid filesystem (eg. -i < -I, or -I x -N > device size).

I don't think it matters if there is a space between the argument and the value or not.
