Transferring from NFS mounts can miss data if agent host is not configured as NFS root host Print


Summary

Transferring data from an NFS mount can miss data and/or remove data if a synchonizing transfer is being used. 

Discussion

When transferring data from NFS mounts, it is very important that the transfer agent host be in the list of both 'read/write' hosts AND 'root hosts'. That is, hosts that can access the NFS export with root permissions.

The reason behind setting the 'root user' list is is that permissions on files can be removed from even the root user across NFS. This can cause data to be missed in the case of a new replication or, if the host is removed from the root list after an initial replication, data deletion can occur if the synchronize option is enabled.
