Description of problem: Moving one storage domain to maintenance makes the entire data center unusable. The SPM contention moves from one host to another and it never succeeds as the following traceback can be found in vdsm.log: Thread-708::ERROR::2013-10-17 17:13:23,196::task::850::TaskManager.Task::(_setError) Task=`04c8d8de-c8fe-4ecf-9651-c837278de8c3`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 857, in _run return fn(*args, **kargs) File "/usr/share/vdsm/logUtils.py", line 45, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/storage/hsm.py", line 2562, in getStoragePoolInfo if domInfo[sdUUID]['isoprefix']: KeyError: 'isoprefix' Version-Release number of selected component (if applicable): is19 How reproducible: 100% Steps to Reproduce: 1. put one of the domain in maintenance Actual results: The entire storage pool remains in the contending state (unusable) and the SPM moves from one host to another.
