Bug 1455693

Created attachment 1282374 [details]
Pool creation failure

Description of problem:

When importing a cluster you must select a single Monitor node, this monitor node must be running the Calamari-server. The cluster imports but does not utilize other monitor nodes that contain calamari-server for resilience, if you turn off the monitor node (simulating failure of device) the RHSCON can no longer perform common operations.


Version-Release number of selected component (if applicable):
calamari-server-1.5.5-1.el7cp.x86_64
python-cephfs-10.2.5-37.el7cp.x86_64
ceph-selinux-10.2.5-37.el7cp.x86_64
libcephfs1-10.2.5-37.el7cp.x86_64
ceph-base-10.2.5-37.el7cp.x86_64
ceph-mon-10.2.5-37.el7cp.x86_64
ceph-common-10.2.5-37.el7cp.x86_64
rhscon-core-0.0.45-1.el7scon.x86_64
rhscon-ceph-0.0.43-1.el7scon.x86_64
rhscon-core-selinux-0.0.45-1.el7scon.noarch
rhscon-ui-0.0.60-1.el7scon.noarch


How reproducible:
Every time

Steps to Reproduce:
1. Import cluster from RHSCON
2. Turn off monitor node used during import
3. Attempt to create a pool

Actual results:
Failure to create pool

Expected results:
Pool should be create

Additional info:
The import process detects all monitor nodes, these monitor nodes should all be listed as possible calamari-server servers, it appears that the monitor node used to import the cluster is hard coded as the only calamari-server. If a monitor node is down then the RHSCON should simply use one of the other additional monitor nodes.
