[HPDD-discuss] How to create multiple oi.16

Hello I got a quite old now Lustre filesystem, formatted with Lustre 2.1 and upgraded to 2.5.3 now. It has an only one OI index file: oi.16 This file is very big -rw-r--r-- 1 root root 82G Feb 10 2012 oi.16 Filesystem has 90 M files currently. - I'm pretty sure this file should not be so big regarding the number of inodes we got. Is there a way to fix this? - Is there a way to upgrade the filesystem to several OI files like Lustre is creating now for a recent Lustre version? Thanks Aurélien
