Hi all,

can someone please provide a link about how to size the disk or how to set the rotation in order to avoid the disk of running full?

Current state:

The index set shows:  
**Total:** 57 indices, 127,538,709 documents\*\*, 40.3GiB\*\*

but the disk shows about **150 GB used.**

So the index set data does not match the real used disk space!?

he @shadesofgraylogger

did you have replicas configured? how many shards did you have? what elasticsearch version did you have?

Hi all,

I`m not sure about the elasticsearch version, but my question is a general one. How can I calculate the total disk space for all my indexes? Should be an easy question , isn`t it ?
