Hi,
Today we rebooted a node in our cluster for maintenance and after that
one of the keyspaces went missing. This is what we did leading up to
this:
nodetool drain -h localhost
reboot
restart cassandra
There was an error during startup:
ERROR [MutationStage:109] 2012-08-08 14:05:56,443 RowMutationVerbHandler.java
(line 61) Error in row mutation
org.apache.cassandra.db.UnknownColumnFamilyException: Couldn't find cfId=1014
(then we found keyspace twitter is missing)
The sstables are still there so I tried to re-create the keyspace:
cassandra-cli -h localhost
[default@unknown] create keyspace twitter with placement_strategy =
'org.apache.cassandra.locator.SimpleStrategy' and strategy_options =
{replication_factor:3} ;
b890b65a-40a6-3fc5-838d-34d58368cb64
Waiting for schema agreement...
... schemas agree across the cluster
NotFoundException()
default@unknown] use twitter;
Keyspace 'twitter' not found.
So we can't create the keyspace. The cassandra version is 1.1.0.
What is the proper way to deal with this?
Thanks for your help.
