Red Hat Bugzilla – Bug 144954
Magma arbitrarily chooses cluster infrastructure if multiple are running
Last modified: 2009-04-16 16:16:07 EDT
Description of problem:
Magma picks the first cluster infrastructure it can connect to when
initializing. If two cluster infrastructures are running, then it
will choose the first from the readdir() operation.
While this is a 100% unsupported use case, it is thought that we may
want to protect against this particular situation.
- List plugins in /etc/cluster/magma.conf with full path. Only try
(2) A bit more complex:
- Assign priorities to magma plugins.
This will be fixed in the following manner, given that this is
(1) Magma will sort the directory entries by name, and try to load
them in alphabetical order (case-sensitive). Thus, gulm.so will be
tried before sm.so. It is not neccesary to weigh one infrastructure
(2) Any file not having the "S_IRUSR" mode bit set will be ignored.
This is useful for testing.
Patches committed to CVS.
