I run into similar problem few weeks ago . You need to run : tunefs.lustre --writeconf /dev/.............
On MDT/MGS after unmounting it , maybbe there is another way to do that without unmounting MDT/MGS but im not sure .

I am trying to learn how to replace a defective OST with a new one. Assuming the old OST can not be salvaged. I have a test cluster that I am working on. I deactivated the volume on the MGS using: lctl conf_param content-OST0002-osc.osc.active=0 I unlinked all of the bad files by finding the ones on the bad volume. I formatted a fresh OST using the index number of the bad device: mkfs.lustre --reformat --fsname content --ost [EMAIL PROTECTED] --param="failover.mode=failout" --index=02 /dev/md6 Then I tried to mount the freshly formatted OST into the cluster. Unfortunately, I end up with an error: mount.lustre: mount /dev/md6 at /lustre_raw_ost_one failed: Address already in use The target service's index is already in use. (/dev/md6) How can I re-use the index number to prevent always having a “dead” point in my cluster?
