OK, I will check the logs. |

From the log we can see that there were two lustre file systems mounted on this client node and each lustre filesystem had tens of OSTs at least. During the log time, the client node (lustre client) was restarted five times. Ihara, to understand the issue clearly, could you please introduce more details about the system environment and related operations? Thanks. |
