Subject RE: IndexFetcher cannot download index file
Date Tue, 24 Apr 2018 12:52:24 GMT
Forget about it, recovery got a No space left on device but it wasn't
clear until i inspected the real logs.

The logs in de web admin didn't show the disk space exception, even when i expand the log
line. Maybe that could be changed.

> Hello,
> Slightly different questions/problem, what is going on here on 7.2.1? During the recovery,
none of this node's fellow replicas indexes were changed but we still got this error.

got updated and recovery failed again. I can understand the second failure, but not the first.

indexing cycle is started. Do i really need to stop the indexer and let the node finish recovery?
Can we do something about that?

50 GB between those nodes. While recovering, CPU utilization is normal/low.
