Hi,
I want to backup an elasticsearch-oss:7.2.0 cluster running in Kubernetes and restore it into a new one elasticsearch:7.2.1 running within ECK
I created a snapshot which looks like to be good (40GB of data)
curl /_snapshot/my_repo/snap1 --> SUCCESS after about 10mn
However, when I restore it into the new cluster, it seems that indices with large datasets are missing:
curl /_snapshot/my_repo/snap1/_restore -d'
{
"ignore_unavailable": true,
"include_global_state": true,
"rename_pattern": "index_(.+)",
"rename_replacement": "restored_index_$1"
}'
Running /_cat/indices on old then new cluster shows that some data are missing:
OLD CLUSTER: green open ind1 aBoy4sS6Tp6_a9Xu3zuuMw 1 1 75 359 1mb 558.8kb
NEW CLUSTER: green open ind1 Dt8NrsYAQRGEfqOa049jPQ 1 1 75 7460 868.5kb 434.2kb
OLD CLUSTER: green open ind2 22IYbVNBSNWmHHKHpoAcmQ 1 1 62592 17113 2gb 773.1mb
NEW CLUSTER: red open ind2 WsbAoc6nSpylZWqnzXvI-A 1 1
Any idea how to debug this ?
Find any error message ?
Am I missing something to run such backup from my old DB to the new one ?
Thanks a lot for your help!
