Check a Directory
Check that an OpenIO namespace has been fully deployed. This checks the directory of services.
| meta0 | Check that meta0 services are registered on zookeeper. |
| meta1 | Check that meta1 services are reachable. |
| dir | Check that prefixes are reachable and are the same as prefixes on meta0, and check if meta1 services are registered on meta0. |
| rdir | Check that all rawx services have associated rdir and check that rdir are up. |
Preparation
You can check if services are UP using openio cluster list
Launch check
Run oio-check-directory <NAMESPACE> <ACTION>. ACTION is a value among meta0, meta1, dir, rdir.
For example you can check meta1 on the namespace named OPENIO with:
$ oio-check-directory OPENIO meta1
The result can be:
07/09/2018 03:11:03 Catalog: Loaded 21 services 07/09/2018 03:11:03 Catalog: Loaded 21 services 07/09/2018 03:11:03 All the META1 are alive 07/09/2018 03:11:03 All the META1 have a positive score
You can use the option --catalog to check if services present in conscience are the same as services in catalog.
Each line of catalog represents a service and must be formatted like Type IP PORT.
You can generate a catalog using openio cluster list -c Type -c Addr -f value | tr ':' ' '
