Suggested Answer: BC 🗳️
ENOSPC is a UNIX operating system error that sometimes returns the message Not enough space is available to service your request." The error message occurs because of a shortage of file system space or lack of available media blocks.
You can delete Snapshot copies manually, or automatically by enabling the Snapshot autodelete capability for the volume.
Define and enable a policy for automatically deleting Snapshot copies by using the volume snapshot autodelete modify command.
You can use the snap delete command to delete a Snapshot copy before the preset interval to free disk space or because it is a manual Snapshot copy that is no longer needed but is not going to be automatically deleted.
Note: We get ENOSPC errors because Data ONTAP lets the Snapshot copy grow into the volume space. Every write in WAFL is a write to a new block. If an old block is part of a Snapshot copy, Data ONTAP needs to preserve the old block and the new changed block. This is not a problem specific to NetApp. Every storage vendor who supports a snapshot feature has to deal with it. There are two options when there is no space to accommodate the Snapshot copies:
✑ Delete old Snapshot copies as the Snapshot copies grow to reduce delta
✑ Preserve the older Snapshot copies and generate an error on the active file system
