Description Martijn ten Heuvel 2020-03-24 15:56:25 UTC

Description of problem:
When installer fails for whatever reason, in my case the iscsi gave some issues, /var/tmp/installvm* is not cleaned. This means that with a couple reruns, /var/tmp will be full:

[root@rhv1 tmp]# ls -als | grep local
4 drwxrwxr-x.  2 vdsm kvm  4096 Mar 24 15:53 localvm_25EXd
4 drwxrwxr-x.  4 vdsm kvm  4096 Mar 24 15:22 localvmVvspJr
[root@rhv1 tmp]# du -sh local*
4.0K	localvm_25EXd
4.5G	localvmVvspJr

Version-Release number of selected component (if applicable):
4.3.8

How reproducible:
Easy

Steps to Reproduce:
1. Setup rhvh node
2. Run installer from cockpit.
3. Stop at storage.

Actual results:
Disk full.

Expected results:
Reuse of resources. Now, omnipotency does not exist; also meaning redeployment is actually a full redeploy.

let's check why /var/tmp got filled. If bootstrap VM content was created there the code should be smart enough to know what to do with the content there.

Comment 2 Asaf Rachmani 2020-08-19 14:20:28 UTC

ovirt-hosted-engine-cleanup tool cleans /var/tmp/localvm*.
Can we run the cleanup tool from cockpit when clicking "Yes" in "Exit Wizard" only after "Prepare VM" stage?
