Errors: MasterNotDiscoveredException, IndexMissingException


(aditya.kulkarni) #1

Hi,

Documents stored previously (worked smoothly for last few days)
Json document is of following format:
"user": "123",
"file_name": "gftgf",
"file_extension": "xls",
"path":"temp"
Installation is on Ubuntu with service wrapper.

Now today, I executed queries:
test@Aditya ~
$ curl -XPOST 'http://localhost:9200/storage/fileinformation/_search?pretty=true' -
d '
{
"query": { "match_all": {} }
}'
{
"error" : "IndexMissingException[[fbdata] missing]",
"status" : 404
}

$ curl -XPOST 'http://localhost:9200/storage/fileinformation/' -d '
{
"user": "123",
"file_name": "gftgf",
"file_extension": "xls",
"path":"temp"
}'

{"error":"MasterNotDiscoveredException[]","status":500}
test@Aditya ~
$

When I checked for data folder, it is present with storage sub folder and index in it.

Cluster Settings

cluster:
name: datastore

Gateway Settings

gateway:
recover_after_nodes: 1
recover_after_time: 5m
expected_nodes: 2

Please note, although it mentions expected_nodes as 2, in reality for test setup I have only one.

Q1: As I can see files present, please advise, how do I get this back in action/make them usable with current instance.

Q2: I will also appreciate, any advise on what should be alternatives for avoiding this problem in real deployment senarios.

Best Regards,
Aditya

Small typo in settings, cluster name is data and not datastore (Got that copied while writing here from local setup where I am trying to reproduce problem with another machine :frowning: )
Apologies!

Are you using just a single node for this and get the mentioned exceptions? Can you gist the cluster state in this case?

Hey Shay,

It is not cluster, it is single machine. As mentioned, it is test setup.

Best Regards,
Aditya


(Shay Banon) #5

Sure, can you gist the cluster state response?

Here it is:

$ curl -XGET 'http://localhost:9200/_cluster/state'
{"error":"MasterNotDiscoveredException[]","status":500}


(Shay Banon) #7

CAn you gist the log of that node? You might need to restart it.

Okay something changed now with restart today & no changes from my side (had tried this after Shay's suggestion, but had no luck)

ES is back: Steps taken
Cleaned data directory and replaced with backup from Mar-18

Still wondering what may have gone wrong. Till this problem is reproduced, i guess keeping backup of data everyday or X hours is safe bet.

Just for a note, for this kind of use case where in installation is on dedicated server with index is simplefs or mmapfs, additional option of saving backup to s3 should be enabled. This shall help in need for taking backups manually or using external tools.

Best Regards,
Aditya


(Shay Banon) #11

Did you remove the gateway configuration by any chance? The recore_after and expected parameters?

Nope. Those were same as mentioned before. that's what makes it more interesting problem.

Trying crazy to reproduce same problem on another machine in different network. If I get to reproduce it, i shall get back to you.

One thing that i observed is that when installed with service wrapper to run in service mode (ubuntu 10.04LTS), it do not start autmatically if network is down (unplugged rj45) and started later.
