I'm facing again the same issue as this post.

Here my glance api log,

I'm uploading a 30G vmdk disk image. I do not think it is a problem of space in nfs datastore (36% used, available space 370GB).

Here the output of df command:

root@havana-controller:/var/log/glance# df
Filesystem                      1K-blocks      Used Available Use% Mounted on

x.x.x.x:/openstack/glance 597688320 209738624 387949696  36% /var/lib/glance/images

Any hint on possible solutions will be appreciated. Thanks in advance.


I tried copying the 30GB vmdk file on /var/lib/glance/images/ and it perfectly worked:

root@havana-controller:/var/lib/glance/images# ls -ltrh

So I could exclude any issue related on running out of space on the NFS share.

Thanks in advance for any suggestion, Antonio

Just so you are aware you posted your glance mysql public address and password, I have removed that conf file link from your post. Feel free to revert my edit if you so wish.

I do remember this issue from previously. I had asked around at this time. No one that I spoke with had seen this before (when space _wasn't_ the issue).

This issue seems to have the same symptoms, though they talk about running glance behind apache WSGI, which I don't think you are doing. Nevertheless, you might think about trying out that while loop instead. It does talk about being near the last chunk of the file that it fails on, just like you.

My only new suggestion would be trying v2 api for glance and seeing if that resolves it for you.

Also opening up a bug for the issue. If someone can reproduce it, it can get fixed.

The problem happens only with NetApp FAS. The issue were not related for sure with space on nfs share.

Our workaround consists on switching on standard NFS exposed by a linux machine, and the issue does not appear anymore.

As soon as we get a better comprehension of the phenomenon we will post the right solution here.

Thanks for your help!

Ah yes. The NetApp. It has never played well with others in my experience. I would love to see the issue get resolved because as Openstack gets more widely adopted you can be assured you wont be the only one to experince that issue.

I am hitting this as well. Can you check whether restart of glance does help? I think it may be some auth timeout issue. ( ( (
