Description Paul Cuzner 2015-01-15 01:29:54 UTC
Description of problem:
for hyperconverged there isn't a tool available that preps the server for use as a hyperconverged node. Tasks would include
- network configuration
- storage configuration
  - raid card detect
  - detect ssd and hdd
  - raid set build - interface to raid card utils/api
  - dmcache configuration (writethrough)
  - lv creation from raidset
  - association of lv's to cache lv's
  - creation of filesystem
  - mount via fstab
  - create glusterfs volume
  - optimise volume for virt store
  - optimise glusterd
    - base-port 49217
    - rpc-auth-allow-insecure on
  - apply additional volume tuning
    - network.ping-timeout 10
    - cluster.quorum-type auto
    - cluster.server-quorum-type server
    - server.allow-insecure on
- firewall configuration
- nfsmount.conf changed to "Lock=False"

Such a tool could also provide the mechanism for prepping new nodes into an existing cluster.

Perhaps this could be something similar to the rhev-h configuration tool?

not sure I understand what ovirt component actually requires this tool

> not sure I understand what ovirt component actually requires this tool

:) To be honest I don't know where this requirement sits. ovirt or rhev? The bottom line is for a converged solution there is a prep phase for the server that needs to occur prior to the gluster config and hosted-engine install.

I raised this so we track this requirement.

not sure I understand, why don't you just install this package prepare whatever you need. then deploy host?
