sstablerepairedset

This tool is intended to mark specific SSTables as repaired or unrepaired. It is used to set the repairedAt status on a given set of SSTables. This metadata facilitates incremental repairs. It can take in the path to an individual SSTable or the path to a file containing a list of SSTables paths.

Do not run this command until you have stopped DataStax Enterprise on the node.

Use this tool in the process of migrating an installation to incremental repair.

Usage:

sstablerepairedset [--really-set] [--is-repaired | --is-unrepaired]
[-f sstable-list | sstables]

Tarball and Installer No-Services path:

<installation_location>/resources/cassandra/tools/bin

Procedure

Choose SSTables to mark as repaired.

$ sstablerepairedset --really-set --is-repaired data/data/cycling/cyclist_name-a882dca02aaf11e58c7b8b496c707234/la-1-big-Data.db

Use a file to list the SSTable to mark as unrepaired.

$ /sstablerepairedset --is-unrepaired -f repairSetSSTables.txt

A file like repairSetSSTables.txt would contain a list of SSTable (.db) files, as in the following example:

/data/cycling/cyclist_by_country-82246fc065ff11e5a4c58b496c707234/ma-1-big-Data.db
/data/cycling/cyclist_by_birthday-8248246065ff11e5a4c58b496c707234/ma-1-big-Data.db
/data/cycling/cyclist_by_birthday-8248246065ff11e5a4c58b496c707234/ma-2-big-Data.db
/data/cycling/cyclist_by_age-8201305065ff11e5a4c58b496c707234/ma-1-big-Data.db
/data/cycling/cyclist_by_age-8201305065ff11e5a4c58b496c707234/ma-2-big-Data.db

Use the following command to list all the Data.db files in a keyspace:

find '/home/user/datastax-ddc-3.2.0/data/keyspace1/' -iname "*Data.db*"
