Hi team, here's a new case.
Problem Symptom
A user attempts to expand the capacity, but after two hours, the expansion times out due to certain reasons.
Then, the user attempts to delete the storage pool, but the operation fails.
Problem Diagnosis
After two hours, the expansion timed out, as shown in the following figure.

If the capacity expansion cannot be completed in two hours, a failure is reported, as shown in the preceding figure. When you attempt to delete the storage pool to restore data, the following error is displayed:

Run the following commands on the active node where the EDS is located:

The preceding figure indicates that the storage pool is successfully deleted.
Causes
If a capacity expansion task times out due to other reasons (such as inherent problems), it will be automatically re-executed periodically until it is successful. The capacity expansion process and storage pool deletion process are mutually exclusive. If a storage pool deletion task is delivered when the failed capacity expansion task is being re-executed, the deletion task fails due to timeout.
Solution
Check whether the capacity expansion process is being executed. If yes, wait until the capacity expansion process completes and go to 2. (The recommended check interval is 5 minutes. If the capacity expansion process does not complete in 30 minutes, contact technical support engineers.)
If the capacity expansion process is being executed, information similar to the following figure is displayed. That is, status of FLOW_SCALE_OUT and FLOW_CLS_SCALE_OUT is Running.

If the capacity expansion process is not being executed, information similar to the following figure is displayed:

Delete the storage pool again on DeviceManager or by running the following commands on the CLI:
cd /opt/dsware/client/bin
./dswareTool.sh --op deleteStoragePool -id 0 -force 1

Check whether the commands are executed successfully.
If yes, no further action is required.
If no, go to 3.
Contact technical support engineers.
