[lustre-discuss] changing inode size on MDT

[Hebenstreit, Michael]

http://wiki.lustre.org/Lustre_Tuning#Number_of_Inodes_for_MDS

and I'd like to use --mkfsoptions='-i 1024' to have more inodes in the MDT. We already run out of inodes on that FS (probably due to an ZFS bug in early IEEL version) - so I'd like to increase #inodes if possible

Are you talking about the inode size, or the “-i” option to mkfs.lustre (which actually controls the ratio of inodes to free space)?
