Ontap simulator 9.6 vol0 full

NickRedstar — Wed, 04 Jun 2025 11:10:39 GMT

I installed ontap 9.6 simulator and my vol0 ran out of space. I disabled all the snapshots on aggregate and volumes and still did not help.

-Node cluster1-02 is in an unhealthy state

-aggregates for cluster1-02 are showing in unknown state

-Resizing does not work of the vol0

-rebooted the node multiple times

Hi,

You haven't mentioned if you tried deleting the vol0 snapshots. Disabling will prevent further snaps, but if there are already existing then you can get rid of them.

cdot-01> snap delete -a vol0
Are you sure you want to delete all snapshots for volume vol0? y

Assuming you gained space after deleting snaps.

cdot-01> df -hg vol0

If it has?

Then, re-size it before rebooting.

cdot-01> vol size vol0 +1g

I Usually keep min 2g for vol0, always take a vmware snap before using it.

Let us know.

Thanks!

thanks, i deleted the snapshots on vol0.It looks like that it took some time for the simulator to recognize that snapshots were deleleted. I left my simulator running over night and rebooted it in the morning. Finally the node 2 started working again. I logged in to ONTAP system manager and Aggregate0 was showing full , so i added extra disks in order to increase space.

Overall your steps are correct in resolving this vol0 being full issue. Thanks for your help.

The issue that you faced is very common with the simulators

To avoid this in future you can also disable the snapshots on the root vol using the command from node shell

Cluster1-01> snap sched vol0 0 0 0

Cluster1-01> snap sched vol0

Volume vol0: 0 0 0

Once you do this you wont have to worry about the root vol being full due to snapshots.
