Hello, I've a SolrCloud of four instances on Amazon and the EBS volumes that contain the data on everynode is going to be full, unfortunately Amazon doesn't support expanding the EBS. So, I'll attach larger EBS volumes to move the index to.
I can stop the updates on the index, but I'm afraid to use "cp" command to copy the files that are "on merge" operation. The copy operation may take several hours. How can I move the data directory without stopping the instance? Thanks, Mahmoud
