How To Grow EBS Volumes on AWS
erics, Posted June 27th, 2014 at 9:29:02pm
PROCEDURE FOR NON-ROOT FILESYSTEMS:
- Run the df command and record the device path for the mount point you wish to grow.
- Unmount the filesystem to insure consistency.
- Detach the volume from the instance.
- Create a snapshot of the unmounted filesystem.
- Create a volume from the snapshot, specifying a larger size in the new volume form.
- Attach the new volume to the same device path.
- Mount the filesystem.
- For XFS:
sudo xfs_growfs -d /{mount_point} - For EXT[2,3,4]:
sudo resize2fs /dev/xvdN
HOUSEKEEPING WHEN EVERYTHING IS TESTED AND WORKING:
- Delete the snapshot.
- Delete the old volume.
