Dropped (or truncated) Table (or keyspace) and Disk Space is not Reclaimed
|
|
==========================================================================
|
|
|
|
This troubleshooting guide describes what to do when ScyllaDB keeps using disk space after a table or keyspaces are dropped or truncated.
|
|
|
|
Problem
|
|
^^^^^^^
|
|
|
|
When performing a ``DROP`` or ``TRUNCATE`` operation on a table or keyspace, disk usage is not seen to be reduced.
|
|
Usually this is verified by using an external utility like the ``du`` Linux command.
|
|
This is caused by the fact that by default, ScyllaDB creates a snapshot of every dropped table. Space won't be reclaimed until the snapshot is dropped.
|
|
|
|
Solution
|
|
^^^^^^^^
|
|
1. Locate ``/var/lib/scylla/data/<your_keyspace>/<your_table>``. Inside that directory you will see a ``snapshots`` subdirectory with your dropped data. Follow the procedure to use nodetool to :doc:`remove the snapshot </operating-scylla/procedures/backup-restore/delete-snapshot>`.
|
|
2. If you are deleting an entire keyspace, repeat the procedure above for every table inside the keyspace.
|
|
3. This behavior is controlled by the ``auto_snapshot`` flag in ``/etc/scylla/scylla.yaml``, which set to true by default. To stop taking snapshots on deletion, set that flag to false and restart all your scylla nodes.
|
|
|
|
.. note:: Alternatively you can use the ``rm`` Linux utility to remove the files. If you do, keep in mind that the ``rm`` Linux utility is not aware if some snapshots are still associated with existing keyspaces, but nodetool is.
