[ezhische]

Trying to change subnets for redis host. terraform plan show:

Terraform will perform the following actions:

yandex_mdb_redis_cluster.redis will be updated in-place

~ resource "yandex_mdb_redis_cluster" "redis" {
id = "c9qln1edmn48p3psa7la"
name = "crm-lt-redis"
# (14 unchanged attributes hidden)

  ~ host {
      ~ subnet_id        = "e9bl3mtomfkchvvlam21" -> "e9bcrrfrtum07h5s2b0n"
        # (5 unchanged attributes hidden)
    }
  ~ host {
      ~ subnet_id        = "e2l6jf5vinoq3qbgnoub" -> "e2ldem29n22nhi863hbe"
        # (5 unchanged attributes hidden)
    }
  ~ host {
      ~ subnet_id        = "fl8pbukuau8eslhkkf3s" -> "fl8aek9hlk198v5vbdbd"
        # (5 unchanged attributes hidden)
    }
  ~ host {
      ~ subnet_id        = "e9bl3mtomfkchvvlam21" -> "e9bcrrfrtum07h5s2b0n"
        # (5 unchanged attributes hidden)
    }
  ~ host {
      ~ subnet_id        = "e2l6jf5vinoq3qbgnoub" -> "e2ldem29n22nhi863hbe"
        # (5 unchanged attributes hidden)
    }
  ~ host {
      ~ subnet_id        = "fl8pbukuau8eslhkkf3s" -> "fl8aek9hlk198v5vbdbd"
        # (5 unchanged attributes hidden)
    }

    # (4 unchanged blocks hidden)
}

Hello! Thank you for reporting the issue. It's not currently possible to change the subnet_id for host. However, the plan is indeed displayed incorrectly, and we will try to fix this soon.
