doveadm(nfsnobody) Error

[横山航平]

Please tell me about maillog Error.

I get the following error in maillog：

－－－
dovecot: doveadm(nfsnobody): Error: sync: User init failed
dovecot: doveadm(nfsnobody): Error: User initialization failed: Namespace
'': mkdir(/var/lib/nfs/Maildir) failed: Permission denied
(euid=65534(nfsnobody) egid=65534(nfsnobody) missing +w perm: /var/lib/nfs,
dir owned by 0:0 mode=0755)

I am using Dsync and the configuration is below：

－－－
service replicator {
  process_min_avail = 1
}

dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u
plugin {
  mail_replica = remote:root@XXX
}

service aggregator {
  fifo_listener replication-notify-fifo {
    mode = 0777
  }
  unix_listener replication-notify {
    mode = 0777
  }
}

service replicator {
  unix_listener replicator-doveadm {
    mode = 0600
  }
}

replication_max_conns = 10

plugin {
  # When saving a new mail via IMAP or delivering a mail via LDA/LMTP,
  # wait for the mail to be synced to the remote site. If it doesn't finish
  # in 2 seconds, return success anyway.
  # replication_sync_timeout = 2s
}

Is the Dsync setting bad?
please tell me.
