I mean insert/write data. When data fills memtable, memtable is flushed to disk
as sstable, when new sstable is created, Cassandra will check if compaction is
needed and triggers one.

Enough to write 1 column and run nodetool flush.

Thanks for the reply Viktor, but the whole cluster has been working all the
time and I am sure the cf got writes every second. I still don't see the
huge sstables being split into small ones

To trigger LCS you need to write to this CF and wait when new sstable flushes.
I can’t find any other way to start LCS.

What you mean 'you need write to this CF'? I've changed the schema by using
CQL3 'alter table' statments.

If you want to trigger a conversion to LCS of the on-disk sstables, doing
nodetool compact cf should achieve what you want.
Be warned, if you have a lot of data in the CF, this could potentially take
a while depending on your compaction throttling.
Thanks,

I tried to run 'nodetool compact' (or with keyspace and cfname), seemed not
woking. The command hung there and nothing happened. But I noticed that
there was about more 3+ pending tasks when using 'nodetool
compactionsats'
