[jira] [Commented] (VCL-693) VCL Cluster Reinstall Fails
[ https://issues.apache.org/jira/browse/VCL-693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13669413#comment-13669413 ]
Nathaniel Sherry commented on VCL-693:
--------------------------------------
After applying the following patch:
"add the following line to the beginning of the reload_image subroutine in new.pm:
delete_computerloadlog_reservation($reservation_id, '!begin');
Just above the 'my $node_status;' line. Then restart the vcld service."
As per request, I checked vcld.log when reinstalling a cluster, after the request state flipped to "reserved", and did see the warning:

> VCL Cluster Reinstall Fails
> ---------------------------
>
> Key: VCL-693
> URL: https://issues.apache.org/jira/browse/VCL-693
> Project: VCL
> Issue Type: Bug
> Components: vcld (backend)
> Affects Versions: 2.3.1
> Environment: CentOS, libvirt/kvm
> Reporter: Nathaniel Sherry
> Labels: cluster, vcld
>
> It seems that when I reinstall a cluster from the "Current Reservations" page, the post_reserve scripts don't get run on the child nodes. I think the issue is that vcld isn't spawning a child process for the child nodes when invoking reserved.pm after finishing new.pm during the reinstallation. The comptuer state of the child is also left at "Reloading".
> This results in the "Connect" button never reappearing.
