You will have severe memory problems under load with this many OSTs. Is there a reason not to make larger OSTs (up to 8TB is supported). > However, MGS doesn't seem to be working properly. > After mount.lustre /dev/VolGroup00/mdt /mnt/mdt/, checking > /proc/fs/lustre/mds/user-MDT0000/recovery_status > returns "status: INACTIVE". This is not harmful, it just means recovery was never run on this OST, and that is normal if it was shut down cleanly.
