[jira] [Commented] (VCL-905) VMware code should ignore files under
.snapshot directories
[ https://issues.apache.org/jira/browse/VCL-905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14743835#comment-14743835 ]
ASF subversion and git services commented on VCL-905:
-----------------------------------------------------
Commit 1703001 from [~arkurth] in branch 'vcl/trunk'
[ https://svn.apache.org/r1703001 ]
VCL-905
Added VMware.pm::find_datastore_files. It calls the OS module's find_files and prunes files under .snapshot directories. Changed calls in VMware.pm and vSphere_SDK.pm from find_files to find_datastore_files.
Other
Updated vSphere_SDK.pm::get_registered_vms to detect "Unknown" VMs and not include them in the return array. This was causing many warning messages in vcld.log.

> Some Netapp and other storage units may automatically create copies of the contents of a volume on a schedule. For Netapp units, snapshot copies are stored under a _.snapshot_ directory on the volume. This directory may be accessible from the VM host. It is possible to configure the volume so that this directory is not displayed on hosts, however, this is not the default.
> Problems occur if the _.snapshot_ directory is accessible on the VM host because the VCL code may attempt to alter the files contained in it. As an example, if the code attempts to delete a VM for which a copy of its working directory was saved in a Netapp snapshot:
