Hi Roman,
If it affects only a subset of nodes and it's always the same ones, it
could be a "problem" with your data model : maybe some (too) wide rows on
theses nodes.
If one of your row is too wide, the deserialisation of the columns index
of this row can take a lot of resources (disk, RAM, an
Hi Christian,
The problem you mention (violation of constency) is a true one. If I have
understood correctly, it is resolved in cassandra 2.1 (see
CASSANDRA-2434).

Hello,
The problem is described here :

The recommended way to avoit it is to use jna.

Hi Nicolas,
What does nodetool ring says ? (Ask every node)
Have you checked that the list of seeds in every yaml is correct ?
What version of cassandra are you using ?

Hi,
To verify that the repair was successful, you can look for this kind of
messages in the log :
INFO [AntiEntropyStage:1] 2012-05-19 00:57:52,351 AntiEntropyService.java
(line 762) [repair #e46a0a90-a13c-11e1--596f3d333ab7] UsersCF is fully
synced (3 remaining column family to sync for t
files should eventually get to that
size.
Anyone else ?
Cheers

Hi,
We are using a 9 nodes cassandra cluster, and each node is currently
handling about 40GB of data.
Our CFs were created using LevedCompactionStrategy, with the default
options (size of SSTables = 5MB).
So the number of SSTables was going quite large, which led to problems

Hi,
It is not enough to run the repair in one node, except if the node contain
all the data (ex : 3 node cluster with RF=3).
In the general case, the best is to launch the repair in every node, with
the "-rp" option (use -rp to repair only the first range returned by the
partitioner)
