Subject: [PATCH 252/255] glusterd: do not mark skip_locking as true for
|
|
|
14f8ab |
geo-rep operations
|
|
|
14f8ab |
|
|
|
14f8ab |
We need to send the commit req to peers in case of geo-rep
|
|
|
14f8ab |
operations even though it is a no volname operation. In commit
|
|
|
14f8ab |
phase peers try to set the txn_opinfo which will fail because
|
|
|
14f8ab |
it is a no volname operation where we don't require a commit
|
|
|
14f8ab |
phase. We mark skip_locking as true for no volname operations,
|
|
|
14f8ab |
but we have to give an exception to geo-rep operations, so that
|
|
|
14f8ab |
they can set txn_opinfo in commit phase.
