Logan B commented on CLOUDSTACK-6938:
-------------------------------------
Understandable, though a bug that makes existing features unusable seems like
it should be fixed sooner rather than later. Since I would doubt 4.5 will
release before September I think something this simple should be looked at.
I'm attempting to come up with a patch, test it, and submit it for review, but
having never done any real development before I don't know if I can get it in
and approved before an RC build.
> Cannot create template from snapshot when using S3 storage
> ----------------------------------------------------------
>
> Key: CLOUDSTACK-6938
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6938
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Snapshot
> Affects Versions: 4.4.0
> Environment: KVM + S3 Secondary Storage
> Reporter: Logan B
> Priority: Critical
> Fix For: 4.4.0
>
>
> When trying to create a template from a snapshot with S3 secondary storage,
> the command immediately fails with a NullPointerException.
> This appears to only happen when there is a pre-existing snapshot folder in
> the NFS staging store. This indicates that there is something wrong with the
> copy command (e.g., it's using 'mkdir' instead of 'mkdir -p').
> The issue can be worked around by deleting the existing snapshot folder on
> the staging store every time you want to create a new template. This is
> obviously not viable for end users.
> This issue should be fixed before 4.4 ships because it should be a stupid
> simple thing to correct, but completely breaks restoring snapshots for end
> users. Waiting for 4.5 would be far too long for an issue like this.
