Hi Dear Percona Support Team,  
When I joined a node to the cluster, it started with an SST process. After that, I noticed the presence of `gcache.page` files when I checked the `datadir`. Below are the relevant  
Actually Database size sync another Databases. Why this file increases?

**configurations:**  
**MYSQL Settings:**  
[mysqld]  
server-id=61  
datadir=/DB/mysql  
socket=/var/run/mysqld/mysqld.sock  
log-error=/var/log/mysqld.log  
pid-file=/var/run/mysqld/mysqld.pid  
log-bin=/LOG/cluster-binlog  
log\_slave\_updates  
expire\_logs\_days=7  
**WsrepConf:**  
[mysqld]  
wsrep\_provider=/usr/lib/galera3/libgalera\_smm.so  
wsrep\_cluster\_address=gcomm://10.100.2.61,10.100.2.62,10.100.2.63  
wsrep\_provider\_options=“gcache.size = 25G”  
binlog\_format=ROW  
default\_storage\_engine=InnoDB  
wsrep\_slave\_threads= 12  
wsrep\_log\_conflicts  
innodb\_autoinc\_lock\_mode=2  
wsrep\_node\_address=10.100.2.61  
wsrep\_cluster\_name=test-cluster  
wsrep\_node\_name=test-cluster-node-1  
pxc\_strict\_mode=PERMISSIVE  
wsrep\_sst\_method=xtrabackup-v2  
wsrep\_sst\_donor=test-cluster-node-3  
wsrep\_sst\_auth=“sstuser:s3cretPass”

Have you read through this blog post? [All You Need to Know About GCache (Galera-Cache)](https://www.percona.com/blog/all-you-need-to-know-about-gcache-galera-cache/)

> gcache will not release the pages until it is safe to do so (until the data has been safely replicated to all the nodes).
