Expand MongoDB Disk Space

the mongodb pods store data in the /var/openebs/ directory of the node that the pod is running on in order to increase the disk space available to the mongodb pods, you must expand the volume/partition this directory is mounted on and expand the file system the steps to do this vary based on your storage provider and file system type you must resize the volume on each node in the cluster since each mongodb pod contains the full dataset if your storage provider or file system doesn't support online resizing then you must ensure only one node is offline at a time to ensure proper cluster operation cloud service storage resizing provider documentation aws ebs volumes https //docs aws amazon com/awsec2/latest/userguide/requesting ebs volume modifications html azure azure disks https //docs microsoft com/en us/azure/virtual machines/linux/expand disks gcp gcp zonal persistent disks https //cloud google com/compute/docs/disks/add persistent disk#resize pd file system resizing every file system type (ext3, ext4, xfs, etc ) will have different instructions for resizing see the documentation for your file system type for expanding your file system after increasing the size of the volume/partition
