Brian: Yes, I have looked thru the lists but I could not really get this question answered. tune2fs is a ext2/3 setting, and I though each file I create on a Lustre filesystem an inode gets created on the MDS and the OST as an object.
But, I don't understand how there is that much of a space discrepancy. Also, how does striping account for in inodes? Lets say I stipe a file on 4 OSTs, I suppose 5 (1 for MDS, 4 for OSTs) inodes are occupied, correct? Sorry for a newbie question. TIA On Tue, Aug 19, 2008 at 4:30 PM, Brian J.
