It has been decomissioned and switched off some time last year, but still crops up in the logs. Recently I managed to revive the old hardware, connect it to Lustre. The MDS recognized the node. Then I umounted, which worked without a problem. Nevertheless, the NID keeps reappearing in the logs. Any way to make the MDSes understand that this box is gone for good? Perhaps install a new one with the old IP?
