But for 24 hour interval, Web UI does not working. (cannot connect)

the console can logn, but command does not work.

How to solve this problem

ontapsim::> vserver nfs show

Error: show failed: database sequential_identifier_byname is not open

```

I believe the problem here is that your root volume has filled up as it usually does in the simulator. I just had a look at the deployment instructions for the 9.7 sim and I see they've removed this bit. Go have a look at page 40 & 41 of the 9.5 guide here and perform those instructions. You'll probably have to reboot as well.

Thank you for your help.

Around page 40 and 41, two instruction exists. both instruction should be executed?

Disabling root snapshots
Expanding the root volume size

I change svm0_root from 20MB to 800MB. by using volume size expantion by using page 41 of Simulator 9.5 document .

I also disable snapshots for root volume (vol0).

The reason for chaning size is the ontap simulator freezes again.

Is there any error messages in the console? Can you send a screen shot?

Yes, perform both procedures, p40 & p41.

Thank you for your comment, I expand the vol0.

Yesterday's error screen shot is follows.

After I met following error, I do disabling root snapshot and expanding the root volume size.

Previously the vol0 size is 800MB, currently I update to 1.50GB.

Also svm0_root is 20MB previously, so changed to 800MB.

Current volume sizes are follows
