means the modification time is different and is being updated to the sender’s value

(requires --times). An alternate value of T means that the time will be set to the transfer
time (without --times).

–

means the permissions are different and are being updated to the sender’s value

(requires --permissions).

–

means the owner is different and is being updated to the sender’s value (requires

--owner and super-user privileges).

–

means the group is different and is being updated to the sender’s value (requires

--group and the authority to set the group).

–

means the atime is different and is being updated to the sender’s value.

–

means the CIFS ACL is different and is being updated to the sender’s value.

–

means the POSIX extended attributes are different and are being updated to the

sender’s values.

Another possible output for %i is - when deleting the files, the "%i" represents the string
"*deleting" for each item that is being removed.

Troubleshooting remote replication

Continuous remote replication fails when a private network is used

Continuous remote replication will fail if the configured cluster interface and the corresponding
cluster Virtual Interface (VIF) for the Fusion Manager are in a private network on either the source
or target cluster. By default, continuous remote replication uses the cluster interface and the Cluster
VIF (the ibrixinit -C and -v options, respectively) for communication between the source
cluster and the target cluster. To work around potential continuous remote replication communication
errors, it is important that the ibrixinit -C and -v arguments correspond to a public interface
and a public cluster VIF, respectively. If necessary, the ibrix_crr_nic command can be used
to change the server assignments (the server/NICs pairs that handle remote replication requests).

Truncating a file during replication

If a file is truncated while it is being replicated, the file is replicated successfully, but a Domain
scan failure message is displayed. Also, an error message is logged in the ibrcfrworker.log
file. The text of the message is similar to the following:

rsync: read errors mapping "/mnt/ibrix/filter/tasks/5/ifs1/test.dat": No data available (61)

rsync: read errors mapping "/ifs1/test.dat": No data available (61)

You can ignore these error messages. The file was replicated successfully.
