different from the source cluster.

Data stream error: ibrcfrworker returned error 12 (RERR_STREAMIO), which
can be expected in retention-enabled environments (WORM) when CRR cannot modify a
retained file on the target cluster.
To avoid these errors, set the auto-commit period to a higher value (the minimum value is five
minutes and the maximum value is one year).
Attempts to edit retained files can create empty files
It you attempt to edit a WORM file in the retained state, applications such as the vi editor will be
unable to edit the file, but can leave empty temp files on the file system.
Applications such as vi can appear to update WORM files
If you use an application such as vi to edit a WORM file that is not in the retained state, the file
will be modified, and it will be retained with the default retention period. This is the expected
behavior. The file modification occurs because the editor edits a temporary copy of the file, tries
to rename it to the real file, and when that fails, deletes the original file and then does the rename,
which succeeds (because unretained WORM files are allowed to be deleted).
Cannot enable data retention on a file system with a bad segment
Data retention must be set on all segments of a file system to ensure that all files can be managed
properly. File systems with bad segments cannot be enabled for data retention. If a file system has
a bad segment, evacuate or remove the segment first, and then enable the file system.
