Can the gcache.page files save to a different location. Currently they are in the datadir but i would like to store them in another mount.

Thanks. How to auto purge those files? My datadir filled up with the files and my cluster failed. I am moving the gcache.page to another directory. The 5 node cluster was in sync.

Shutdown MySQL, delete them, change the variable, start mysql. They are just cache files and transactions will be fetched if the local node does not have them.

I deleted the `galera.cache` file which allowed the nodes to join the cluster.

Is there a way to have them auto purge or limit how many I keep? They are filling up HD space fast, which will lock up my system again.
