Hi team! I often encounter the following error when i insert documents to my index. > elasticsearch.exceptions.AuthorizationException: AuthorizationException(403, 'cluster\_block\_exception', 'blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];') As a temporary workaround i use one of the following, i index successfully some docs, but again after a while i see the same error. ``` PUT _settings {"index": {"blocks": {"read_only_allow_delete": "false"}}} PUT /_settings { "index.blocks.read_only_allow_delete": null} ``` How can i permanently fix it? Searching on the web didn't found a permanent solution to this issue, apart from the workarounds i mention above. I have enough disk space in the Elasticsearch instance and this error occurs even when my index is empty! What is wrong here? Cluster info: ``` { "name" : "rLNxkrB", "cluster_name" : "elasticsearch", "cluster_uuid" : "7GjE59rERPeuOyk1PAzDyQ", "version" : { "number" : "6.6.1", "build_flavor" : "default", "build_type" : "zip", "build_hash" : "1fd8f69", "build_date" : "2019-02-13T17:10:04.160291Z", "build_snapshot" : false, "lucene_version" : "7.6.0", "minimum_wire_compatibility_version" : "5.6.0", "minimum_index_compatibility_version" : "5.0.0" }, "tagline" : "You Know, for Search" } ``` ...and my index settings: ``` { "settings" : { "index" : { "number_of_shards" : 3, "number_of_replicas" : 2 } } ``` ... and disc usage info (my indices that i created are the yellow ones): ``` health status index uuid pri rep docs.count docs.deleted store.size pri.store.size yellow open fertilization O_yvMFedS0SA3qsOd12GwA 3 2 0 0 783b 783b yellow open monitoring mausy_dxTTW1JiB88g7lWA 3 2 0 0 783b 783b green open .reporting-2019.12.01 CMSHgEkDQ_S7kuz4fRI2Dg 1 0 1 0 10.8kb 10.8kb yellow open augmenta_snapshots hqU4hp14SCmR6BtkJCHxyg 3 2 1 0 11.5kb 11.5kb green open .reporting-2019.11.17 T5Q8qUJTTXeECng9bHWczw 1 0 2 0 20.5kb 20.5kb green open .kibana viyg013TT0yanW3qmvTaNA 1 0 32 2 151kb 151kb green open .reporting-2019.12.08 HZ0Fsxd5RBqimiJ_5dwjOw 1 0 6 2 388kb 388kb green open .monitoring-kibana-6-2020.01.12 UqZsn-A9QJyfKUZfRkWfEw 1 0 3226 0 884.6kb 884.6kb green open .monitoring-kibana-6-2020.01.11 aSBTioOrR7e6ejZwruZfaw 1 0 3111 0 886.2kb 886.2kb green open .monitoring-kibana-6-2020.01.13 o0ixyC_nQt2TwsdT0v51CQ 1 0 3602 0 956.9kb 956.9kb green open .monitoring-kibana-6-2020.01.10 VkVVfVwmREGXZcQpKBeHFA 1 0 3408 0 978.6kb 978.6kb green open .monitoring-kibana-6-2020.01.16 F9KLSx4UQAuUTIzXybVG-A 1 0 3825 0 1mb 1mb green open .monitoring-kibana-6-2020.01.14 9t1nOBx_QlWZPpJjRqhgyg 1 0 6304 0 1.5mb 1.5mb green open .monitoring-kibana-6-2020.01.15 RHbxXJJhQE2_Z_3f4VyTxg 1 0 8639 0 2.1mb 2.1mb green open .monitoring-es-6-2020.01.12 GToNe2rpT0-p5wdFyWnzIg 1 0 147730 306 55.9mb 55.9mb green open .monitoring-es-6-2020.01.11 ikJa_VhZS9K419yIq4QIjA 1 0 142595 243 58.5mb 58.5mb green open .monitoring-es-6-2020.01.10 jWRUwxBRRgOjrP8ivNJugg 1 0 161332 672 60.6mb 60.6mb green open .monitoring-es-6-2020.01.16 bdLeDXy9SDmsNCIGfmoemw 1 0 139641 424 63.8mb 63.8mb green open .monitoring-es-6-2020.01.13 TqjMNZcET1CwQRIdLzQuww 1 0 166226 651 67mb 67mb green open .monitoring-es-6-2020.01.14 9_uLKbBuQ5-dvEnsRxoxIg 1 0 243080 812 101.7mb 101.7mb green open .monitoring-es-6-2020.01.15 IXCPlrtgRPCoKBic-yt60Q 1 0 293130 536 130.2mb 130.2mb yellow open npk S1exfiWiThmtc7iCwdD1_Q 3 2 86832 0 182.1mb 182.1mb ``` Conciselly my disk space info: ``` "fs": { "timestamp": 1579175865660, "total": { "total_in_bytes": 10222829568, "free_in_bytes": 569589760, "available_in_bytes": 552812544 ``` Thank you in advance! ---

> [@johnkary](#): > > I have enough disk space in the Elasticsearch instance No, you don't. Here's the disk usage you shared: ```auto "total_in_bytes": 10222829568, "free_in_bytes": 569589760, ``` Your disk is ~95% full, so Elasticsearch is switching to read-only mode to protect itself from the consequences of a completely full disk. The solution is to free up some disk space. ---

@DavidTurner really thank you for the quick response! I thought that 552 Mb as free space were enough but yes, if the threshold for switching to read-only mode is 95%, then it's ok. I 'm gonna increase the virtual disk space in the VM where elasticsearch is installed. But it's weird, it seems that from 10 Gb the 9,5 are full and i don't know from what? From my post here above, all the indexes in my cluster have total size not bigger than 500 Mb. The other? ---

Can you share the output from `GET _cluster/health` and `GET /_stats/translog,store?filter_path=_all.**.size_in_bytes`? ---

Cluster health: ``` { "cluster_name": "elasticsearch", "status": "yellow", "timed_out": false, "number_of_nodes": 1, "number_of_data_nodes": 1, "active_primary_shards": 30, "active_shards": 30, "relocating_shards": 0, "initializing_shards": 0, "unassigned_shards": 24, "delayed_unassigned_shards": 0, "number_of_pending_tasks": 0, "number_of_in_flight_fetch": 0, "task_max_waiting_in_queue_millis": 0, "active_shards_percent_as_number": 55.55555555555556 } ``` ... and the output from the second command: ``` { "_all": { "primaries": { "store": { "size_in_bytes": 764579223 }, "translog": { "size_in_bytes": 630941765 } }, "total": { "store": { "size_in_bytes": 764579223 }, "translog": { "size_in_bytes": 630941765 } } } } ``` **Note** : that i just increased the VM disk space from 10Gb to 30Gb and then i run the command you shared to me. So, these results now are after the disk space increase. ---

Ok, Elasticsearch thinks it's in charge of 764+630MB of data, i.e. just under 1.5GB. The other 8GB of disk usage seems to be nothing to do with Elasticsearch. ---

Fine! Finally i found that the rest 8Gb were logs of the VM instance! I handled it and now i am ok! Thanks again @DavidTurner for your help! ---
