Failed to sync translog java.io.IOException: Input/output error

Elastic Stack Elasticsearch

Hey,

I'm receiving this error quite often ( every 5-10 seconds) from my indices and even marvel index.

From my indices when I bulk index 200-1000 documents from a single machine in a single thread.

And from marvel when the system is idle:

I'm running 1.7.1 and its an EC2 single node with EBS volumes raid0.

How bad is this?

Best regards,

Doesn't look good, can you run a FS check?

thanks for the tip.

I used mdadm raid0 on amazon EBS.
Once I changed the database to use only one EBS volume instead of mdadm it started working properly again.
