Steps required for increasing disk size in EC2 instance with minimal downtime

[RAJAMOHAN <garajamohan@xxxxxxxxx>]

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.

xvdf    202:80   0  700G  0 disk  
└─md127   9:127  0  5.5T  0 raid0 /opt/postgres
