Created attachment 758066 [details] screenshot of error Description of problem: Resolving missing hook is showing "Internal Engine Error" for the first time. But the file is actually getting removed from the back-end. However, if we perform the action again, it succeeds in the UI as well. Following traceback is seen in the vdsm logs: ---------- Thread-135756::DEBUG::2013-06-06 21:06:05,104::BindingXMLRPC::913::vds::(wrapper) client [10.70.36.85]::call hooksList with () {} flowID [2dddf26b] Thread-135756::DEBUG::2013-06-06 21:06:05,109::BindingXMLRPC::920::vds::(wrapper) return hooksList with {'status': {'message': 'Done', 'code': 0}, 'hooksList': [{'status': 'ENABLED', 'name': '30samba-stop.sh', 'level': 'PRE', 'md5sum': '6589a82125403778c5b23eb60975a49e', 'command': 'stop', 'type': 'text/x-shellscript; charset=us-ascii'}, {'status': 'ENABLED', 'name': '29CTDB-teardown.sh', 'level': 'PRE', 'md5sum': 'c5b3ca8c807d768be881b3c7fd2e4beb', 'command': 'stop', 'type': 'text/x-shellscript; charset=us-ascii'}, {'status': 'ENABLED', 'name': '30samba-start.sh', 'level': 'POST', 'md5sum': '675ee7cf03e125dcacbec3fba523bbfc', 'command': 'start', 'type': 'text/x-shellscript; charset=us-ascii'}, {'status': 'ENABLED', 'name': '29CTDBsetup.sh', 'level': 'POST', 'md5sum': '7eb10305bd3611b04479b90a34fd026b', 'command': 'start', 'type': 'text/x-shellscript; charset=us-ascii'}, {'status': 'ENABLED', 'name': '30samba-set.sh', 'level': 'POST', 'md5sum': 'e1dae56e96326aa8ea26544a3254b748', 'command': 'set', 'type': 'text/x-shellscript; charset=us-ascii'}, {'status': 'ENABLED', 'name': '32binaryhooknew.sh', 'level': 'POST', 'md5sum': '9f38bf50e3d8f709bbd2e9afa0b8b0ee', 'command': 'set', 'type': 'application/x-executable; charset=binary'}, {'status': 'ENABLED', 'name': '33resolvehooktest1.sh', 'level': 'POST', 'md5sum': '1a0b8481099094d97ad35f7668d5ed63', 'command': 'set', 'type': 'text/plain; charset=us-ascii'}]} Thread-135757::DEBUG::2013-06-06 21:06:05,314::BindingXMLRPC::913::vds::(wrapper) client [10.70.36.85]::call hookRemove with ('set', 'POST', '33resolvehooktest1.sh') {} flowID [1643b709] Thread-135757::ERROR::2013-06-06 21:06:05,317::BindingXMLRPC::932::vds::(wrapper) unexpected error Traceback (most recent call last): File "/usr/share/vdsm/BindingXMLRPC.py", line 918, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/gluster/api.py", line 32, in wrapper rv = func(*args, **kwargs) File "/usr/share/vdsm/gluster/api.py", line 251, in hookRemove self.svdsmProxy.glusterHookRemove(glusterCmd, hookLevel, hookName) File "/usr/share/vdsm/supervdsm.py", line 76, in __call__ return callMethod() File "/usr/share/vdsm/supervdsm.py", line 67, in <lambda> **kwargs) File "<string>", line 2, in glusterHookRemove File "/usr/lib64/python2.6/multiprocessing/managers.py", line 740, in _callmethod raise convert_to_error(kind, result) UnboundLocalError: local variable 'e' referenced before assignment ---------------- Version-Release number of selected component (if applicable): Red Hat Storage Console Version: 2.1.0-0.bb2.el6rhs How reproducible: Always Steps to Reproduce: 1. Manually create a hook and make sure it got updated in the UI and conflict message will be seen in the Events 2. In the UI, select that hook and click on "Resolve Conflicts 3. Under "Resolve Actions", select the radio button: "Remove the Missing Hook" and click on OK You will see the error at this point! Actual results: File is actually getting removed from the RHS node, but the following error is seen in the UI: --- Error while executing action Remove Gluster Hook: Internal Engine Error --- However, if you try to perform the same action again, it doesn't show this error in the UI and the action succeeds. Expected results: The Resolve action should be successful at any point of time. Additional info: Screenshot attached. vdsm and engine logs will be attached soon.
