Doc's are getting deleted automatically

(kish) #1

Doc in the index are getting deleted automatically from one particular index alone i.e immediately . I am able to see in indices output and very next second it is getting deleted.

One the ES logs i am to see as below when deletion happened.

Problematic index ,
root@cscfhcalloam002> curl -XGET 'localhost:9200/noderegister/_mapping?pretty'

"noderegister" : {
"mappings" : {
"register" : {
"properties" : {
"Address" : {
"type" : "ip"
"NodeName" : {
"type" : "keyword"
"NodeType" : {
"type" : "keyword"
"Uuid" : {
"type" : "keyword"
"noderegister1" : {
"properties" : {
"Address" : {
"type" : "ip"
"NodeName" : {
"type" : "keyword"
"NodeType" : {
"type" : "keyword"
"Uuid" : {
"type" : "keyword"

I am not sure whether this the problem but it might.
First created index is 'register' with type 'register'. later there was some issues so we created other index with name 'noderegister' with type 'noderegister1' and moved all data from 'register' to noderegister and deleted the ole 'register' index and gave alias name 'noderegister' as 'register'.
Above part is perfectly working. And when try to add data it is working but it is getting deleted immediately.

kindly check as huge data is getting deleted.

There is nothing in elasticsearch which does that automatically.

So you have something or someone who is sending those requests to your cluster.

I hope it's not exposed publicly without any protection.

(kish) #3

No, there is no such request coming. We are 100% sure.
And also in indices output also we can see that docs are getting deleted less than 7-10sec.

is there any logs you need or where we can check?

(David Pilato) #4

Try to remove the Network connection. If this is not happening anymore, then my theory is exact.

If it's still happening, run a ps -ef to see what is running locally.

(kish) #5

Could you to explain it? you mean to say external connection? If then it is cluster node with no access to other network elements.
If some process is deleting it then in at least we should be able to see in logs? i dont see any such thing.

(David Pilato) #6

What is the output of

GET /_cat/nodes?v
GET /_cat/plugins?v
GET /_cat/indices?v

(David Pilato) #7

I forgot to ask. Are you running with a old version of elasticsearch and using the now removed TTL feature?

please the details

Any clue/help ?

(David Pilato) #12

Can you trace what are the network connections on each on your 3 nodes on port 9200?

(kish) #13

At present i don't have the setup to share the details, will update once i get the setup.
sorry for Inconvenience
