Magento 2 Solved: cluster_block_exception

error: cluster_block_exception [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has read-only-allow-delete block] .

This error means you do not have enough disk space to store or update data. The flood storage watermark is 95% default, so when it exceeds, the above error is shown and it puts the Elasticsearch into read-only mode. So you need to free up disk space or enlarge it.

Steps to Solve Reindex issue with Elasticsearch: run below cmd

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

php bin/magento indexer:reindex

Magento 2 Add Attribute Name To Configurable Select Option 'Choose a option..'

Configurable products display 'Choose an option...'. with Attribute option label like 'Color Choose an option...'


You also need to change that text in below file,

vendor/magento/module-configurable-product/view/frontend/web/js/configurable.js
In this file, you need to find _fillSelect method and see "chooseText" value.

element.options[0].innerHTML = this.options.spConfig.chooseText

Replace with below code


var attribute_lable = this.options.spConfig.attributes[element.id.replace(/[a-z]*/, '')]['label']; element.options[0].innerHTML = attribute_lable +' ' + this.options.spConfig.chooseText;
