Raplace String to FixedString(N). it can work. You can try it like:

CREATE TABLE IF NOT EXISTS metrics.samples_local ON CLUSTER [cluster name]
(
  date Date DEFAULT toDate(0),
  name String,
  tags Array(FixedString(N)),
  val Float64,
  ts DateTime,
  updated DateTime DEFAULT now()
)ENGINE = GraphiteMergeTree(date, (name, tags, ts), 8192, 'graphite_rollup');```
