EBS Volume Stuck at 72% Since 5+ Hours (Urgent)

After 24 hours the optimization process completed.

Hello,

While the volume is in the optimizing state, your volume performance is in between the source and target configuration specifications. Transitional volume performance will be no less than the source volume performance. If you are downgrading IOPS, transitional volume performance is no less than the target volume performance.

Volume modification changes take effect as follows:

• Size changes usually take a few seconds to complete and take effect after the volume has transitioned to the Optimizing state.
• Performance (IOPS) changes can take from a few minutes to a few hours to complete and are dependent on the configuration change being made.
• In some cases, it can take more than 24 hours for a new configuration to take effect, such as when the volume has not been fully initialized. Typically, a fully used 1-TiB volume takes about 6 hours to migrate to a new performance configuration.
