bq. In all my solr servers I have 40% free space Well, clearly that's not enough if you're getting this error: "No space left on device"
Solr/Lucene need _at least_ as much free space as the indexes occupy. In some circumstances it can require more. It sounds like you're having an issue with full replications all happening at the same time and effectively at least doubling your index space requirements. I'd fix that problem first, the other messages likely will go away. Either get bigger disks, make your indexes smaller or move some of the replicas to a new machine.
