I think I missed the gist of your problem before. Let me know if this
sums it up:
1) You are using NUFA to prioritize the local node access
2) The local node is close to full, but the other nodes are not
3) When writing from that node, a no free disk space error is returned,
even through there is plenty of space on other nodes
