hello i want to ask about sst percona cluster
previously i tried site to site using percona cluster version 8.4 with fresh installation, and it worked, then i tried to provide data from mysql standalone that had been backed up using xtrabackup on one of the site nodes.xtrabackup runs normally until the re-bootstrap process of node 1 on site A, then I try to join node 3 which is on site 3, it fails with the following statement:
innobackup.backup.log in node 1
