I posted this to linux-ha, but maybe this is better place?
I am trying to find easy-to-use distribution and/or tool for managing
cluster with:
- 2 hosts
- drbd replication between hosts
- HA for virtual machines & drbd
But can't find anything that really fits my requirements, so I created a
script...
Now I have Scientific Linux 6 x86_64 installed in 2 identical machines
with this configuration:
- Gigabit ethernet between hosts
- KVM virtualization
- Pacemaker/Corosync, configured with DRBD-MC
- LVM volume group, named "vg01" with free space for VM's
- public key authentication, so I can run commands in both hosts
When I run my script with "create" parameter, it will do the following:
- Ask name for new virtual machine (GUI with zenity :) )
- Ask disk size for VM
- Create logical volume in both hosts
- setup DRBD replication for volumes
- Create new VM and configure it to use /dev/drbd? as harddisk
- Open Virtual Machine Manager so user can modify settings for VM
- Configure cluster to take care of drbd & VM
And with "delete" parameter it will remove cluster , VM, drbd and lvm
configs for selected VM.
I hope someone with programming skills can try and improve this ( a lot
:-) )

Asking people on a mailing list to open a zip file attachment is not
going to get very far. Can you set this up on github or the like?
