Hi,<br>
<br>
I'm attempting to download a large file which I have uploaded to<br>
SoftLayer Object Storage using the swift tool. It's downloading only the<br>
manifest and is not downloading the segments. Any tips on figuring out<br>
what is going wrong?<br>

It's entirely possible that the cluster in question lacks static large object support. Maybe they're running an old version of Swift (pre-1.8.0/Grizzly), or maybe they haven't enabled the static large object feature.<br>
<br>
What you'll need to do is probe the cluster to see if static large objects are enabled.<br>
<br>
The easy way is to politely ask the cluster with a GET request to /info. Run `swift stat -v`, then take the "StorageURL" field and change the path to be just "/info". Strip off any path that's already there.<br>
<br>
For example, if the output looks like<br>
<br>
StorageURL: <a href="http://192.168.22.2:8080/v1/AUTH_test" target="_blank">http://192.168.22.2:8080/v1/<u></u>AUTH_test</a><br>
Auth Token: AUTH_<u></u>tk89454677b67348e09eefc1d6fe4d<u></u>fa68<br>
Account: AUTH_test<br>
Containers: 1<br>
[...]<br>
<br>
then you'd simply run<br>
<br>
curl <a href="http://192.168.22.2:8080/info" target="_blank">http://192.168.22.2:8080/info</a><br>
<br>
The response will be a JSON hash, so maybe run it through a JSON pretty-printer, e.g.<br>
<br>
curl <a href="http://192.168.22.2:8080/info" target="_blank">http://192.168.22.2:8080/info</a> | python -mjson.tool<br>
<br>
On my development machine, the response looks something like this (some items removed for brevity):<br>
<br>
{<br>
"container_quotas": {},<br>
"formpost": {},<br>
"slo": { <---- LOOK FOR THIS<br>
"max_manifest_segments": 1000,<br>
"max_manifest_size": 2097152,<br>
"min_segment_size": 71<br>
},<br>
"swift": {<br>
"account_listing_limit": 10000,<br>
"container_listing_limit": 10000,<br>
"max_account_name_length": 256,<br>
"max_container_name_length": 256,<br>
"max_file_size": 5368709122,<br>
"max_meta_count": 90,<br>
"max_meta_name_length": 128,<br>
"max_meta_value_length": 256,<br>
"max_object_name_length": 1024,<br>
"version": "1.12.0.106.ga08e813"<br>
}<br>
}<br>
<br>
If you don't see SLO in there, then you're out of luck. Bug Softlayer and see if they'll turn it on.<br>
<br>
Now, it's also possible that you'll get a 412 response with the body "Bad URL" when you run the curl command above. That will tell you that the cluster is running 1.11.0 or earlier, but it won't tell you anything about SLO support. In that case, try uploading a normal file (cat picture or something) with the header "X-Static-Large-Object: yes". If that succeeds, then SLO is disabled; if SLO is enabled, then the PUT will fail.<br>
