Snapshot - No space left on device -

RGRAETZNRC — Thu, 05 Jun 2025 07:29:55 GMT

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.

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.

I suggest opening a case with Netapp on this.
