Also, what is that ideal way of deleting a lot of mappings from ES without running into IO issues?
Delete the full index if you can. It is really really faster than deleting a mapping (means deleting all docs for this type). Basically, it's a rm -rf on each node which is extremly fast and frees your disk space immediatly.

Hi Alex,
I deleted the complete mapping using the REST interface and not used a delete by query. Also, There was no time gap between these mapping deletion and I fired them one after another.
I haven't captured the log after the node failure but on restarting the cluster in foreground, it was printing some log messages regarding trying to recove index_name
I know this is partial information, but still any help would be appreciated.

Thanks,

Hey,
do you have any more information than "the cluster died"? Have you checked your logfile and looked out for the exceptions? What happened on restarting when you increased the log level for more information?
Did you simply delete the index, or did a delete-by-query which is going to cause a lot of IO and may render your system unresponsive (thus leading to dead cluster). Any more information would really help us a lot! Thanks!

Hi,
I had around 70G of data across 40 indices in ES, I delete 36 of these indices using REST api (curl call). after that the 2 node cluster died and I was not able to restart the cluster. I had to delete the data directory.
Is this is a common scenario? Am I missing something or there is any specific way to delete multiple indices in quick succession.
Thanks,
Anand
