Hello everyone!
I have an ES 6.1.3 installation that works perfectly, but now the disk where the indexes are stored (we can call it 'Disk A' with path '/data-ephemeral') is full and we can't make it larger.
So I've decided to make another slower disk ('Disk B' with path '/data-persistent') and move all the indexes of the 'Disk A' on it to make space available on that disk for the new indexes.
To make a test, as a first step, I've copied the indexes and tested ES. The operations I've made are:
- stopped the ES service;
- run an 'rsync' (rsync -av ) between the two disks;
- changed the 'path.data' parameter in the 'elasticsearch.yml' configuration file to point the new disk;
- started the ES service.
At this point I've noticed that ES was down and the logs was full of errors. Here an extract:

I also notice this kind of error:

Did I miss some operations? Do you have any hint on what's going on?
