Hi Facundo I tried disabling wal archive by setting wal archive and wal path both to same directory <property name="storagePath" value="/opt/ignite/persistence/"/> <property name="walPath" value="/opt/ignite/wal/"/> <property name="walArchivePath" value="/opt/ignite/wal/"/> <property name="walMode" value="FSYNC"/>
But again I faced the same issue, it was running fine for 10 hours and at this time i connected to visor to check number of records and the total records were around 200 million records and after disconnecting from visor, I connected to sql line and ran select count(*) from table; not sure which one caused wal disk to fill completely. I deployed this Ignite cluster with JAVA 11 -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
