3.1.2 Automatic recovery for secondary MDS failures

If the secondary MDS process fails, operation is not affected. The secondary MDS is automatically started again as the secondary MDS in preparation for a failure of the primary MDS process. In this case, the following process is performed:

1) Restarting the failed MDS

The MDS is restarted as a secondary MDS.

In a file system in which three or more MDS node are set, if the secondary MDS does not work after the specified time, a secondary MDS can be activated from another MDS node to continue operations.

2) Making the restarted secondary MDS effective

The AC performs the processing necessary for recognizing the restarted secondary MDS.
