* PUMP: perform opendir on pump xlator instead of its childPranith K2011-06-161-4/+2
| | | | | | | | | | | | | | | | | | | | | | When replace-brick is performed, there is a high probability for the directories on the source brick to not have any pending entry xattrs. So for proper self-heal we need the force merge to kick in. If the opendir is performed on pump xlator directory is examined and if the entries on its children do not match then force merge is triggered, so missing entries will be created on the sink. Pending xattrs are set from source to sink on the files present on source in this process. So when the lookup happens the self-heal is triggered. Before this fix, the code is working because the self-heal source is decided based on what file is biggest in size which is a wrong and removed.
