This results in the OST going to "partial connect: state when the MDT tried to use the bad nids and also the mount being put into the replay log, so that the partial attach never goes away. It survives a reboot, lustre_rmmod and remount of the MGT and MDT.It gets replayed.</p> <p>The MGS should check all the failover nids (even a simple lctl ping) before accepting the mount, Allowing it to be accepted causes too many problems downstream.</p> LU-8405
