Hi Brian, You are very vigilantly with my setup :-) ... You are absolutely right! I am using 2 slices because i am learning/testing Lustre and i don't have enough equipments and hard disks in order to add more OSTs, so i used one disk with 2 partitions to emulate somehow the second OST :-)). Indeed, i agree with you: on production this setup should be avoided. Thanks again. You are a nice guy ;-) Regards, Alx _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
