edison su commented on CLOUDSTACK-5429: --------------------------------------- It's the default behavior on RHEL: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/sect-gracefully-shut-down-guests-libvirt.html One can change the behavior to shutdown vm, instead of suspend vm, during host shutdown, by modify libvirt-guests, but I think it should be configured by admin, not in cloudstack. > KVM - Primary store down/Network Failure - Hosts attempt to reboot becasue of > primary store being down hangs. > ------------------------------------------------------------------------------------------------------------- > > Key: CLOUDSTACK-5429 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5429 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Management Server > Affects Versions: 4.3.0 > Environment: Build from 4.3 > Reporter: Sangeetha Hariharan > Assignee: edison su > Priority: Critical > Fix For: 4.4.0 > > Attachments: kvm-networkshutdown.png, kvmhostreboot.png, psdown.rar > > > KVM - Primary store down - Hosts attempt to reboot becasue of primary store > being down hangs. > Set up: > Advanced zone with KVM (RHEL 6.3) hosts. > Steps to reproduce the problem: > 1. Deploy few Vms in each of the hosts with 10 GB ROOT volume size , so we > start with 10 Vms. > 2. Create snaposhot for ROOT volumes. > 3. When snapshot is still in progress , Make the primary storage unavailable > for 10 mts. > This results in the KVM hosts to reboot. > But reboot of KVM host is not successful. > It is stuck at trying to unmount nfs mount points. -- This message was sent by Atlassian JIRA (v6.2#6252)
