ZFS snapdir=visible breaks Galera rsync SST replication

    XMLWordPrintable

    Details

      Description

      Using ZFS with the following example config:

      zfs create tank/mysql
      zfs set snapdir=visible tank/mysql
      zfs set mountpoint=/mysql tank/mysql
      

      my.cnf:

      [mysqld]
      datadir=/mysql
       
      [galera]
      wsrep_on=ON
      wsrep_sst_method = rsync
      

      rsync will attempt to sync the .zfs special folder, which breaks rsync (and thus sst replication)

      incoming patch in just a few minutes.
