If you're running Xsan 1.0 or 1.1 with any fibre channel storage, only the first two storage pools may contain metadata. The third or later storage pools should be set to User Data Only.
If the third or later storage pool is configured for any setting other than User Data Only, your controllers may fail over. If this is the case, follow these steps to resolve the issue:
- Unmount the Xsan volume from all clients.
- Stop the Xsan volume.
- Set all storage pools (except for the first two) to be used for User Data Only.
Warning: Changing a storage pool's use will cause the volume to be reinitialized, erasing all data on the volume.
- Click Save.
- Restart the Xsan volume.
