ovirtManageDisk.py

Tool for managing disks for oVirt/RHEV from the command line. Provides the ability to create, attach/detach, delete both internal (pool) disks and direct attach (lun) disks to VMs. Requires ovirtFunctions.py so keep them in the same directory

Before running, you must create a ~/.ovirtparams file in your home directory which contains the connection information for your Manager instance. A sample .ovirtparams file can be found in the repo. You can add multiple connection sections to the file if connecting to multiple different Managers.

Usage

usage: ovirtManageDisk.py [-h] [-r RHEVM] {attach,create,detach,delete} ...

Create, attach, delete RHEV disks

    attach              Attach existing disk to a VM.
    detach              Detach existing disk from a VM.

                        Specify RHEV Manager to connect to

Examples

create 5GB disk and attach to rgtest

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py create -n rgtest -d test_disk -s 5
Will create new disk test_disk with size 5368709120
Created disk: test_disk with size 5368709120

Deactivate but dont detach newly create test_disk from rgtest

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py detach -w -d test_disk -n rgtest
Deactivating disk: test_disk

Detach test_disk from rgtest

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py detach  -d test_disk -n rgtest                             
Disk is already deactivated
Detaching disk test_disk from rgtest

Attach but dont activate test_disk to rgtest

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py attach -w -d test_disk -n rgtest                           
Attaching test_disk to rgtest

Activate test_disk

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py attach -d test_disk -n rgtest                              
Disk test_disk is already attached
Activating disk: test_disk

Deactivate and detach test_disk from rgtest

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py detach -d test_disk -n rgtest                              
Deactivating disk: test_disk
Detaching disk test_disk from rgtest

Permanently delete test_disk

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py delete -d test_disk                                         
Will destroy disk test_disk with size 5368709120. Are you sure? (Y/[N])
y
Disk test_disk deleted

Create direct attach disk and attach to rgtest

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py create -n rgtest -d test_lun -l 3600a098038303053453f463045727459

Detach direct attach disk, note other than creation all commands on internal disks and direct attach disks are the same

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py detach -n rgtest -d test_lun
Deactivating disk: test_lun
Detaching disk test_lun from rgtest

Delete test_lun without prompting for confirmation

[rgroten@rg-rhevm ~] $ ovirtManageDisk.py delete -d test_lun -y
Assuming Yes since -y used...
Disk test_lun deleted

ovirtTestConn.py

Simple python script connects to oVirt/RHEV Manager to check if it's available. Can make it automatically restart the manager service or add in another action like notify admin team.

ovirt-backup-db.sh

This script will backup your oVirt/RHEV Manager database and copy it to a standby host, then cleanup any old backups stored on the standby. Run from cron. As of RHEV/oVirt 3.6 this script can be replaced with a built-in monitor on storage domains.

ovirt-check-storage-pools.sh

Script to alert users if a storage pool fills up beyond a certain threshold. Threshold percentage can be specified in ovirt-check-storage-pools.inf file.
