[library] Zabbix provision fails, os group allocated on more than one disc

[Shaun OMeara]

Output of api/version:

{"ostf_sha": "9863db951a6e159f4fa6e6861c8331e1af069cf8", "auth_required": false, "api": "1.0", "nailgun_sha": "4f6463133145d4d65eeb7d51aedf4641a93c04e0", "production": "docker", "fuelmain_sha": "090d046cf7261fe5ed4305c7c6b615c03761cb8d", "astute_sha": "18a6861ecf96e20ead17782ef4ea8d62e7449c14", "feature_groups": ["experimental"], "release": "5.1", "fuellib_sha": "fc4824e17489ceaa1854d3e3ab2336dafa8e8710"}

Operating System : Ubuntu
Reference Architecture: HA
Network model: Neutron+GRE

Result:
1. Install fails looking for repo, attempts to use Ubuntu public Repo not Fuel master repo
2. Install request local username and password
3. Install requests guided partitioning

Reproduce:

Assigned the Zabbix profile to a node left all other settings default.

Workaround:
Attach to node console:
1. Allow node direct access to the Ubuntu Repositories
2. Assign a username and password
3. Select partitioning manually

Impact:
Fuel waits indefinitely for Zabbix server install to complete the Ubuntu install

Error on provisioning stage

The problem is in default allocation

[Dima Shulyak (dshulyak)]

The problem here is that we are choosing default allocation strategy for zabbix as os - all.
Which results in broken provisioning on ubuntu.
We need to introudce additiona vg in nailgun, probably /var, and allocate only min to os.

    Use mysql-server-wsrep package for zabbix

    The issue with mysql-server - it doesnot do mysql
    install when /var/lib/mysql is present
    it is fixed in mysql-server-wsrep

    Change allocation strategy for zabbix-server

    If user will use zabbix-server on node with more than one
    hard disk, and ubuntu os, it will lead to errors on provsion
    stage for the server

    Mounting /var partition on ubuntu will lead to errors
    cause there is no os volume group on ubuntu

    - add /var/lib/mysql partition, will grow most of all,
      because zabbix is using mysql for storing stats
    - change os vg to use min allocator
