https://bugzilla.redhat.com/show_bug.cgi?id=511276 --- Comment #2 from Mark Hlawatschek <[email protected]> 2009-07-14 11:48:12 EDT --- The open-sharedroot feature is about setting up and managing a sharedroot cluster. I.e. multiple nodes share the same root filesystem. When a single root filesystem is concurrently used for multiple nodes the following topics have to be considered: 1. A shared or cluster filesystem is needed. I agree, we basically do not need python scripts to mount the shared filesystem inside the initrd. In our approach, some configuration items can be defined inside the cluster configuration itself. E.g. network configuration for the cluster/storage interconnect. To be able to query the cluster configuration in a general way (abstraction layer), the comoonics-cluster-py package is needed. In the NFS sharedroot case the whole redhat cluster stack is not needed. Nevertheless the comoonics-cluster-py is used to query a basic configuration file. Another abstracted implementation is going to be ldap queries. 2. The shared root filesystem has to provide host dependent parts for every cluster node. E.g. /etc/sysconfig/network needs to be host dependent. Context dependent symbolic links (cdsl) are provided using --bind mounts. I.e. # mount --bind /cluster/cdsl/[nodeid] /cdsl.local To be able to do this, the id of the current node has to be queried. Also, utilities for managing the cdsls are needed. We provide two utils com-mkcdslinfrastructure and com-mkcdsl for the cdsl management (comoonics-cdsl-py). The cluster query (nodeid) and the cdsl management are implemented in those python packages. -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Fedora-package-review mailing list [email protected] http://www.redhat.com/mailman/listinfo/fedora-package-review
