I think you're right.

eio is I/O error. Reported by the file handle cache that means you're 
seeing errors accessing the disk.

But when you say "sudden crash of my entire cluster" - do you mean a 
disk failure on one node caused failures on other nodes? That would be 
bad! Or were your nodes sharing a disk somehow?
