Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Cause: Since /var is not layered, any new files that exist both on the new image and the running system are not copied from the image. Consequence: Packages that ship files under /var are not updated correctly. Fix: If an updated file exists on both the new image and the running system, the original file will be saved as ".imgbak" and the new file will be copied over. Result: Both original and new files exist under /var.	Story Points:	---

Comment 1 RHV bug bot 2018-11-28 06:57:35 UTC

QE can reproduce this issue.

Test version:
# imgbase layout
rhvh-4.1-0.20180425.0
 +- rhvh-4.1-0.20180425.0+1
rhvh-4.2.7.3-0.20181026.0
 +- rhvh-4.2.7.3-0.20181026.0+1

Test steps:
1. Install redhat-virtualization-host-4.1-20180426.0
2. Check for the contents of virt profile /var/lib/glusterd/groups/virt
3. Upgrade rhvh to 4.2.7 rhvh-4.2.7.3-0.20181026.0
4. Check for the contents of virt profile /var/lib/glusterd/groups/virt
5. Clean install rhvh-4.2.7.3-0.20181026.0
6. Check for the contents of virt profile /var/lib/glusterd/groups/virt


Test results:
1. After step 4, the contents of virt profile is same as step 2:
# cat /var/lib/glusterd/groups/virt
performance.quick-read=off
performance.read-ahead=off
performance.io-cache=off
performance.low-prio-threads=32
network.remote-dio=enable
cluster.eager-lock=enable
cluster.quorum-type=auto
cluster.server-quorum-type=server
cluster.data-self-heal-algorithm=full
cluster.locking-scheme=granular
cluster.shd-max-threads=8
cluster.shd-wait-qlength=10000
features.shard=on
user.cifs=off

2. After step 6, the contents of virt profile is not same as step 4:
# cat /var/lib/glusterd/groups/virt
performance.quick-read=off
performance.read-ahead=off
performance.io-cache=off
performance.low-prio-threads=32
network.remote-dio=enable
cluster.eager-lock=enable
cluster.quorum-type=auto
cluster.server-quorum-type=server
cluster.data-self-heal-algorithm=full
cluster.locking-scheme=granular
cluster.shd-max-threads=8
cluster.shd-wait-qlength=10000
features.shard=on
user.cifs=off
cluster.choose-local=off
client.event-threads=4
server.event-threads=4
performance.client-io-threads=on

Comment 3 Huijuan Zhao 2018-11-29 08:50:12 UTC

This bug is fixed in redhat-virtualization-host-4.2-20181128.0

Test version:
# imgbase layout
rhvh-4.1-0.20180425.0
 +- rhvh-4.1-0.20180425.0+1
rhvh-4.2.8.0-0.20181127.0
 +- rhvh-4.2.8.0-0.20181127.0+1

Test steps:
Same as comment 1

Test results:
1. After step4, the contents of virt profile is different as step 2
2. After step6, the contents of virt profile is same as step 4
So new virt profile has the new content.


So this bug is fixed in rhvh-4.2.8.0-0.20181127.0, will verify this bug once the status move to ON_QA.
