Problems doing AFT on a cluster

[eche1984]

Hi, people !

I have to transfer several files to a file server on a cluster with 2 nodes and the only way i can do it is using SFTP.

When one node falls down and switch to the other one, i can't do any transmision. The error message is something like the AFT recognize that the server's host key has changed and since this is unknown, it can't assimilate the new one that belongs to the switched node and brakes the communication.

Emphasizing that the FTP service is enabled and may not be enabled, i need you to suggest me how can resolve this kind of problems.

I'll be grateful for any help you can give me.

Regards,
Eche

Normaly a file server in cluster must have the same key.
