Subject restoring from snapshot - missing data
Date Sun, 20 May 2012 18:25:27 GMT
I am testing backup and restore.
I created the restore using parallel ssh on all 3 nodes.
I created a new 3 ring setup and used the snapshot to test recover.
Snapshot from every original node went to one of the new nodes.
When I compare the content of the data dir it seems that all files from the
original cluster exist on the backup cluster.
*But* when I do some cqlsh queries it seems as though about 1/3 of my data
is missing.

Any idea what could be the issue?
I thought that snapshot flushes all in-memory writes to disk, so it can't
be that some data was not on the original snapshot.

Help is much appreciated,
