Doc Type: Enhancement
Doc Text:
It was decided to rewrite 'Host Deploy' from scratch as there were to many issues being reported about this component. These included: - Too many bootstrap sequences (standard, node, registration). - No pluggable (cluster). - VDSM-bootstrap is part of VDSM package, however it is back-end tool. - No manual invocation method. - Logging is insufficient, example - SSH timeout issues. The new changes are: - Host Deploy as standalone package. - Lower cost of maintenance. - Lower cost of integration. - Flexible pluggable design. - Two sequences: * Host deploy * Ovirt-node upgrade. - Ovirt-node registration has no ovirt logic, just 'I'm here' notification. - Establish a bidirectional channel between back-end and host. * No iterative commands nor file transfers. - Manual invocation support. - Better timeout management. - Better logging. - Share code with engine-setup.

Description Alon Bar-Lev 2012-11-11 17:34:30 EST
CURRENT ISSUES (nut shell)

* Too many bootstrap sequences (standard, node, registration).
* Too much complexity, can break at a lot of places, hard to adapt new features.
* No pluggable (cluster).
* vdsm-bootstrap part of vdsm package, however it is back-end tool, hard to maintain the dependency and support multiple back-end versions.
* No manual invocation method.
* Logging is insufficient, example: stderr data absent from logs on host, but appear on back-end side.
* SSH timeout issues.
