Обсуждение: Steps required for increasing disk size in EC2 instance with minimal downtime
Hello all,
We have configured RAID 0 setup, with 8 EBS volumes of size 700G. We combined those volumes under a single mount point for the data directory. Archives are configured to be stored on different EC2 instances.Currently disk utilisation of data directory crossed 90%. We need to increase the disk with less downtime.
Can anyone please share with me the steps to increase the disk size in EC2 instances with minimal downtime.
