IWStack outage

Post by Admin » Tue Oct 11, 2016 2:40 am

We are aware of the problems with the IWStack infrastructure.
The cause seems to be a cascade failure and, for now, we do not know what is the reason for it. The problem is ongoing, we will keep updates here.

The service is restored, however, we are still investigating the causes. An aparent slowdown of the network might have caused the issue, but there are no clues on why it happened yet.

It appears that there were multiple problems, among them a network and a caching one. The network problem has been fixed, the cache is bypassed for now.
The service is restored, but we experience a bit of io problems due to the lack of caching.

At this time the service works.
We had some cache issues affecting the storage.
If you experience FS corruption, please shutdown the vm and do a FS check at restart just to make sure. We do not see data corruption, but it is likely the cache delay might have created some small problems.
