Hi all,
I've a little problem with software cluster provided by CentOS 6.2 (cman, rgmanager & cie), VM cluster services and global cluster resources.
Here is my system arch:
--------------- ------------------ |clusternode1 |--+---| GFS2:vmimages1 | --------------- | | | | | VM img 1 | | | VM img 2 | | | VM img 3 | + | ... | | ------------------ | | | --------------- | ------------------ |clusternode2 |--+---| GFS2:vmimages2 | --------------- | | | | | VM img X | | | VM img Y | | | VM img Z | | | ... | | ------------------ | --------------- | |clusternode3 |--+--- ... --------------- | ... |
All my cluster nodes are connected to a SAN which houses some GFS2 fs for VM images files.
I've defined global cluster resources for my GFS2 filesystems where my vm images files are stored. Now i want to add this resources to vm services to makes the cluster aware of VM dependency to the fs which store it image file (to avoid node to try to start VM if it don't have required filesystem or stop VM when it lost the filesystem). When i add global resources to a "normal" cluster service, it works, but it don't when i try to add global resources to a VM service.
I'm the onlyone with this type of configuration ?
Someone know if it's a bug or it's not supported ? I don't find anything about it in cluster documentation/man pages/<cluster commands> --help
Have a nice day.
Regards.
