Comments and/or Workarounds


A failed snapshot may not be deleted when a policy creates two snapshots for multiple volumes in a volume group

This issue is seen only when two snapshots are being created and the first snapshot succeeds whereas the second one fails. The issue is not seen when:
  - multiple snapshots are being created and the first one fails
  - only a single snapshot is created.
CSC-3327 Snapshots or Cloud Snapshots/Clones created for multiple volumes which are a part of a volume group on Web UI are serialized

When snapshots are created for multiple volumes part of a volume group, the snapshots will be created on a per volume basis in sequence.

If the snapshot operation is interrupted, dangling snapshots are left behind in the appliance. The customers won't be able to delete the cloud configurations as the volumes will be 'In Use' by the Web UI. Please contact StorSimple to resolve this issue.

Please also note that the snapshots taken from Web UI Data Protection (in case of volume group with multiple volumes) are not a point in time backup. The backups taken by DPC policies are instead a point in time.

CSC-3277, CSC-3285 Under repeated controller failovers, the appliance can become inaccessible When the controllers are pulled out or reset without an opportunity to shut down or restart gracefully, there is a very rare opportunity that the appliance data would not be properly saved before the failover and the appliance intentionally shuts down waiting for user intervention to prevent accessing incorrect data. Please contact StorSimple support to address such issue in the most appropriate manner.
CSC-3282 Appliance failover is observed when the data read from the cloud is incorrect due to transient network issues This known issue is being actively investigated in conjunction with the cloud providers. The StorSimple system is able to detect and recover from such a situation by performing a failover and never returns any incorrect data to the iSCSI initiator.
CSC-3265 In rare instances, on resetting the active controller, a reboot may happen during the appliance failover Following a 1.2.1  2.0.1 upgrade, in very sporadic instances, the StorSimple software may shut down when attempting to access snapshot related metadata. 
CSC-3253 In rare instances, on resetting the active controller, the Host I/Os may get aborted In some high load scenarios, host I/Os are aborted because the appliance takes more than 20 seconds before completing the operation. The issue subsides after the load reduces.
Workaround: A reduction in host load, and/or a failover of the controller is recommended.
CSC- 3299 The user is able to verify and save an invalid project ID while creating Google Cloud Credentials The Web UI cannot presently identify an invalid project ID at the time of creating Cloud Credentials. However, user will not be able to save a Cloud Configuration that will use these incorrect credentials.
Workaround: Ensure that you are using a valid project ID matching the Google Storage Account that is used for login.
CSC- 3297 Cloud inaccessibility alert is raised for Google Cloud Configuration When more than one set of Cloud Credentials is being used for the same project ID, user is going to see 'Cloud inaccessibility' alerts.
Workaround: Ensure that you are using only one set of Cloud Credential for any given project ID.
