 Hi Jean,

 Thank you for the quick response. I am not sure how to achieve that.
 Can i set the tokens for a node via cqlsh ?

 I know that i can check the nodetool rings to get the tokens allocated
 to a node.

 I was thinking to basically run sstableloader for each of the snapshots
 and was assuming it will load the complete data properly. Isn't that the
 case.

 Thank you.

Re: Restore cassandra snapshots

Hi Pradeep,

Because you use sstableloader, you don't need to restore de system keyspace.

Your procedure is correct to me.

Re: Restore cassandra snapshots

[Pradeep Chhetri]

Hi Anthony

I did the following steps to restore. Please let me know if I missed
something.

- Took snapshots on the 3 nodes of the existing cluster simultaneously
- copied that snapshots respectively on the 3 nodes of the freshly created
cluster
- ran sstableloader on each of the application table. ( I didn't restore
the system related tables ) on all of three node.

I was assuming that since I ran from all the three snapshots, all the
tokens should be there so thought that this will not cause any data loss.

Do you see that I might have data loss. I am not sure how to verify the
data loss although I did ran count of few table to verify the row count.

Thank you the help.

Re: Restore cassandra snapshots

[Anthony Grasso]

Hi Pradeep,

If you are going to copy N snapshots to N nodes you will need to make sure
you have the System keyspace as part of that snapshot. The System keyspace
that is local to each node, contains the token allocations for that
particular node. This allows the node to work out what data it is
responsible for. Further to that, if you are restoring the System keyspace
from snapshots, make sure that the cluster name of the new cluster is
exactly the same as the cluster which generated the System keyspace
snapshots.

Anthony

Quick questions - 1) I have around 2GB of cassandra snapshot - do you
suggest using sstableloader 2) What do you mean by "restore option" - do
you mean copying snapshot dir directly to the nodes of the new cluster ?

Re: Restore cassandra snapshots

[Jean Carlo]

HI,

Yes of course, you can use sstableloader from every sstable to your new
cluster. Actually this is the common procedure. Just check the log of
cassandra, you shouldn't see any errors of streaming.


However, because the fact you are migrating from on cluster of N nodes to
another of N nodes, I believe you can just copy and paste your data node
per node and make a nodetool refresh. Checking obviously the correct names
of your sstables.
You can check the tokens of your node using nodetool info -T

But I think sstableloader is the easy way :)

Hi,

Be sure that you have the same tokens distribution than your original
cluster. So if you are going to restore from old node 1 to new node 1, make
sure that the new node and the old node have the same tokens.

Re: restore cassandra snapshots on a smaller cluster

[Ben Slater]

It should definitely work if you use sstableloader to load all the files. I
imagine it is possible doing a straight restore (copy sstables) if you
assign the tokens from multiple source nodes to one target node  using the
initial_token parameter in cassandra.yaml.

Cheers
Ben
