This > search is not necessary when attaching a volume in Allocated state, due to > volume files don't exist on datastore. > On large datastores, this search can cause volume attachness to be really > slow, as we can see in this log lines: > {code} > 13-mgmt.log:2016-11-02 10:16:33,136 INFO [vmware.mo.DatastoreMO] > (DirectAgent-931:ctx-5687d68e uscrlpdcsesx240.ads.autodesk.com, > job-8675314/job-8675315, cmd: CreateObjectCommand) Searching file > 9ce7731fd38b4045afbb7ce9754abbc1.vmdk in [b5ebda046d613e079b5874b169cd848f] > 13-mgmt.log:2016-11-02 10:19:42,567 WARN > [storage.resource.VmwareStorageLayoutHelper] (DirectAgent-931:ctx-5687d68e > uscrlpdcsesx240.ads.autodesk.com, job-8675314/job-8675315, cmd: > CreateObjectCommand) Unable to locate VMDK file: > 9ce7731fd38b4045afbb7ce9754abbc1.vmdk > 13-mgmt.log:2016-11-02 10:19:42,719 INFO [vmware.mo.DatastoreMO] > (DirectAgent-931:ctx-5687d68e uscrlpdcsesx240.ads.autodesk.com, > job-8675314/job-8675315, cmd: CreateObjectCommand) Search file > 9ce7731fd38b4045afbb7ce9754abbc1-flat.vmdk on > [b5ebda046d613e079b5874b169cd848f] > … > 13-mgmt.log:2016-11-02 10:19:44,399 INFO [vmware.mo.DatastoreMO] > (DirectAgent-931:ctx-5687d68e uscrlpdcsesx240.ads.autodesk.com, > job-8675314/job-8675315, cmd: CreateObjectCommand) Searching file > 9ce7731fd38b4045afbb7ce9754abbc1-flat.vmdk in > [b5ebda046d613e079b5874b169cd848f] > 13-mgmt.log:2016-11-02 10:22:07,581 WARN > [storage.resource.VmwareStorageLayoutHelper] (DirectAgent-931:ctx-5687d68e > uscrlpdcsesx240.ads.autodesk.com, job-8675314/job-8675315, cmd: > CreateObjectCommand) Unable to locate VMDK file: > 9ce7731fd38b4045afbb7ce9754abbc1-flat.vmdk > 13-mgmt.log:2016-11-02 10:22:07,731 INFO [vmware.mo.DatastoreMO] > (DirectAgent-931:ctx-5687d68e uscrlpdcsesx240.ads.autodesk.com, > job-8675314/job-8675315, cmd: CreateObjectCommand) Search file > 9ce7731fd38b4045afbb7ce9754abbc1-delta.vmdk on > [b5ebda046d613e079b5874b169cd848f] > 13-mgmt.log:2016-11-02 10:22:09,745 INFO [vmware.mo.DatastoreMO] > (DirectAgent-931:ctx-5687d68e uscrlpdcsesx240.ads.autodesk.com, > job-8675314/job-8675315, cmd: CreateObjectCommand) Searching file > 9ce7731fd38b4045afbb7ce9754abbc1-delta.vmdk in > [b5ebda046d613e079b5874b169cd848f] > 13-mgmt.log:2016-11-02 10:25:06,362 WARN > [storage.resource.VmwareStorageLayoutHelper] (DirectAgent-931:ctx-5687d68e > uscrlpdcsesx240.ads.autodesk.com, job-8675314/job-8675315, cmd: > CreateObjectCommand) Unable to locate VMDK file: > 9ce7731fd38b4045afbb7ce9754abbc1-delta.vmdk > {code} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
