Netapp volumes by default are created with snapshots turned on; if the volume is being used for backups (for example), the snapshots just use up space.
Here’s how to delete them:
df vm_dev # see space usage for vm_dev volume snap sched vm_dev # see the current snapshot schedule snap sched vm_dev 0 0 0 # zero out the current schedule vol options vm_dev nosnap on # disable snapshots (not required, but "belts and braces") snap delete -a vm_dev # delete all old snapshots
On a multi terabyte volume, the actual deletion can take a while – don’t expect the space to return immediately.
See Netapp’s “Data Protection Online Backup and Recovery Guide” for more details.comments powered by Disqus
