The error is not propagated to the UI when https request fails due to disk space exhaustion

[Sasikiran]

When I try to upload an image which is of100GB through Horizon with https communication on apache2, then I am getting the following error.

"Secure connection Failed. The connection to the server was reset while the
page was loading."

Instead of resetting the connection, it should throw a proper exception handling message.

[Marcos Lobo (marcos-fermin-lobo)]

Is this happening only with httpS?

[Sasikiran (sasikiran-vaddi)]

If it is not https, then it is throwing below error in UI

Danger: There was an error submitting the form. Please try again.

but if it is hptts, then it gives
Resetting the connection, it should throw a proper exception handling message.

I suspect that the real problem here is [Fri Mar 27 06:23:59 2015] [error] IOError: [Errno 28] No space left on device
Once there are no space left on controller node, all kinds of weird things could happen.

The problem with controller node space exhaustion when uploading Glance image is being solved at bug 1403129.

[Sasikiran (sasikiran-vaddi)]

Yes I agree with you Timur

But from horizon the connection is getting lost because of CSRF token. Due to this we cannot navigate to other tabs.
Forbidden (CSRF token missing or incorrect.): /admin/images/create/

Even if it throws a error, there should be a way to handle and throw it on the dashboard UI, so that user can use the dashboard without any interruption.

[Timur Sufiev (tsufiev-x)]

Sasikiran, yes, it actually may be a different bug. Yet IMO we can hardly make any guarantee of work if there is no space at Controller node.

I've edited the summary and removed Duplicate status.
