Please help me to understand it!
My first guess is that vol2 contains LUNs with reserved space and that there is not enough space in the volume to create a new snapshot and still keep the reserved space.

Path: The full path of the LUN, for example /vol/luns/lunOne. You can rename a LUN (path of the LUN can be changed) but the new path must be in the same volume as the original one | |||
Status: Status of the LUN. |
| ||
LUN Protocol Type: Select the multiprotocol type for the LUN. |
| ||
Description: An optional description of the LUN. | |||
Size: The size of the LUN. The current exact size is 859047985152 bytes. | |||
Units: A multiplier for the LUN size. | |||
Space Reserved: Indicates whether this LUN is space reserved. |
| ||
Serial Number: LUN serial number. |
| ||
LUN Share Share option for LUN. By default, when a LUN is created, such access is turned off. Note that choosing write is the same as choosing all. |
space reserved is on ! The picture is not right!
there are no differences... or?
I suggest opening a case with Netapp on this.
