Description of problem: I've tried to create 3 cluster in parallel. It seems that this is not possible because 1st and 3rd clusters creation tasks have time-outed because of 2nd cluster creation task. Please look at log in attachment. I think that if it is not possible to create more than 1 cluster in parallel it should be written in documentation AND UI and core should not allow run tasks like this in parallel. I expect that 1st cluster task installed packages on machines, then 2nd cluster got lock and started to install packages on machines. But 1st cluster task time-outed because 2nd cluster task had lock. 3rd cluster task time-outed because 1st cluster or 2nd cluster task had lock. Version-Release number of selected component (if applicable): ceph-ansible-1.0.5-15.el7scon.noarch ceph-installer-1.0.11-1.el7scon.noarch rhscon-ceph-0.0.20-1.el7scon.x86_64 rhscon-core-0.0.21-1.el7scon.x86_64 rhscon-ui-0.0.34-1.el7scon.noarch How reproducible: 100% Steps to Reproduce: 1. start creating of 1st cluster 2. start creating of 2nd cluster 3. start creating of 3rd cluster 4. wait for timeout some of tasks from 1.,2.,3. Actual results: It is not possible to create more than 1 clusters in parallel. Expected results: It will be possible to create more than 1 clusters in parallel OR ( it will be documented that it is not possible to do that AND UI(from more browsers) and core will not allow to start more than 1 task for creating cluster )
Will Document this for the current release
This is a limitation at ceph-installer level where it supports the execution one task at a time and during the course, USM tasks gets timed out. Talk to ceph installer folks and support for this in 2.0 time frame is not on the cards. So we need to document this behavior
Need to make this a doc bug
