Loosing cache data when persistence is enabled
Dear Team,
We are using apache-ignite-2.7.0 version with 4 worker nodes with 2 servers ( configured 2 nodes in each server) with persistenceEnabled true with zero backups for the cache . When the nodes are restated the data is being lost in few nodes and this behavior is not consistent.
Some times after nodes restart all the data is being restored , after that again if we restart the nodes data lost in few nodes. Some times even after one time restart of the nodes also the data is lost in few nodes.
Kindly provide us the solution why the data is lost even though persistenceEnabled is true and what needs to be done for not to loose data when node restart/node is down

Hi,
The nodes are not getting out of Baseline topology. They are showing offline , after restart of the nodes data is getting deleted from persistence folders(some time data not getting deleted and some times getting deleted). PFA web console

Hi Beela,
could the root cause be that you had changes in your baseline topology when
you saw the data loss? According to my understanding and the answer I got on
my question
http://apache-ignite-users.70518.x6.nabble.com/Ignite-persistence-Data-of-node-is-lost-after-being-excluded-from-baseline-topology-td34675.html
some weeks ago the data of nodes that got excluded from the baseline
topology will be deleted for consistency reasons.
This is just an immediate guess from my side, I did not have a look into
your attachments so far.
Best,
Vincent
