Sounds like a job for "nodetool scrub", which rewrites the SStable rows in the correct order. After the scrub, nodetool repair should succeed.

Is it maybe because I went over the gcgrade period? What you do if you go over that period? Any hint will be valuable, Also I noticed when I run a repair on different node, I see a message like this [2013-05-01 14:30:54,305] Starting repair command #5, repairing 1120 ranges for keyspace struqrealtime I have couple of questions, why I have repair command #5? And why the ranges values changes from one node to another?
