Our current tmp directory is only 5GB and it’s not able to perform SST backup as the tmp directory gets filled up really quickly.
Setting tmpdir under [mysqld] or [xtrabackup] doesn’t work for me. I have also checked the permissions. It is still using /tmp for the SST.
We are using the following version:
Server version: 5.7.16-10-57-log Percona XtraDB Cluster (GPL), Release rel10, Revision bec0879, WSREP version 27.19, wsrep_27.19
Any ideas please?
