Glance image-upload truncates the image.

[Jaroslav Henner]

This may be a DUP of #1240355 but I am not sure.

I have three hosts which all are connected to the same shared NFS datastore and glance configured to use it. I am uploading an image and then try to download, but download returns empty string and there is an ERROR in the glance/api.log:

2014-08-25 09:11:01.438 2724 ERROR glance.api.common [893f9ace-0176-42b1-947f-21b8875547be cffc8c555ebe44bb97b48baabd92e606 94a68b099a674d55986f4ce15fbb946b - - -] Backend storage for image 46b9b487-9c49-47a4-87aa-a11d0b17b6ff disconnected after writing only 0 bytes

@Arnaud, mind looking at this? I think you know the vmware driver better than anyone else here :D

[Flavio Percoco (flaper87)]

Wait, the description says NFS but it was tagged as vmware. @Jaroslav, what store are you actually using?

[Jaroslav Henner (jhenner)]

vmware (vsphere) backend which has datastore configured as NFS. In other words, glance talks to vsphere, vsphere talks to probably to ESXi and those talk to NFS.

[Flavio Percoco (flaper87)]

Have you tested this with other stores? I think this is a vmware specific bug. Either the driver is broken or the store is mis-configured.

[Jaroslav Henner (jhenner)]

I was trying to reproduce what Tempest does. Tempest was failing when using vmware but not when using file backend, so I do think it is vmware specific.

[Jaroslav Henner (jhenner)]

It seems this has been fixed with
python-glance-store-0.4.0-1.el7ost.noarch

[Flavio Percoco (flaper87)]

This has been fixed already
