Hi Ray, it's not safe to remove archive, in release 2.7 ignite will be able to do this: https://issues.apache.org/jira/browse/IGNITE-7912
... Delete unused archived wal segments on each node: control.sh [--host HOST_OR_IP] [--port PORT] [--user USER] [--password PASSWORD] [--ping-interval PING_INTERVAL] [--ping-timeout PING_TIMEOUT] --wal delete [consistentId1,consistentId2,....,consistentIdN] [--force] ... you can try this feature in the nightly build: https://ignite.apache.org/download.cgi#nightly-builds this might be required to enable experimental commands: export IGNITE_ENABLE_EXPERIMENTAL_COMMAND=true if you need this feature in a more stable build, you can try to get a build from GridGain with this feature. Thanks, Mike. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
