Troubleshooting snapshots
Snapshot reserve is full and the MSA2000 is deleting snapshot volumes
When the snapshot reserve is full, the MSA2000 will delete snapshot volumes on the storage array,
leaving the device entries on the file serving nodes. To correct this situation, take the following
steps:
1. Stop I/O or any applications that are reading or writing to the snapshot file systems.
2. Log on to the active management console.
3. Unmount all snapshot file systems.
4. Delete all snapshot file systems to recover space in the snapshot reserve.
CIFS clients receive an error when creating a snapshot
CIFS clients might see the following error when attempting to create a snapshot:
Make sure you are connected to the network and try again
This error is generated when the snapshot creation takes longer than the CIFS timeout, causing the
CIFS client to determine that the server has failed or the network is disconnected. To avoid this
situation, do not take snapshots during periods of high CIFS activity.
