Snapshot - No space left on device -

[#1]

Hello,

i have a problem...and i dont understand why!

Here we are...

We have a fas2050 with vmwares on it.

When i try to Snapshot this appears:

de-ham-san1> snap create vol2 test
Snapshot operation failed: No space left on device.

BUT

de-ham-san1> snap create vol1 test
de-ham-san1>

Works great.

de-ham-san1> df -A -g

I dont see the problem!

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.	online
LUN Protocol Type: Select the multiprotocol type for the LUN.	VMware
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.	BytesWords (double bytes)512 byte blocksKB (KiloBytes)MB (MegaBytes)GB (GigaBytes)TB (TeraBytes)
Space Reserved: Indicates whether this LUN is space reserved.	Space Reserved
Serial Number: LUN serial number.	P3T9doNunXK3
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.	nonereadwriteall

space reserved is on ! The picture is not right!

there are no differences... or?

I suggest opening a case with Netapp on this.
